Brief cognitive-behavioral conjoint therapy ,Intimate relationships ,MDMA ,PTSD - Abstract
BACKGROUND: Posttraumatic Stress Disorder (PTSD) impacts both individual and relational functioning. Veteran couples are at increased risk of relationship distress due to military stressors such as deployment, family reintegration, and traumatic stress. Although both Cognitive-Behavioral Conjoint Therapy (CBCT) and its brief version (bCBCT) consistently have large effects on reducing PTSD symptoms, these treatments have more variable effects on relational outcomes. Given the impact of relationship functioning on the overall health of veterans, improving the effect of PTSD treatments on relationship functioning is an essential area of research. One promising path is the role of MDMA (3,4-methylenedioxymethamphetamine)-assisted therapy in augmenting the relational impact of established therapeutic interventions such as bCBCT. METHOD/DESIGN: This is a single site, open-label study assessing the preliminary efficacy, safety, and acceptability of MDMA-assisted therapy in combination with bCBCT in 8 veterans with PTSD and their intimate partners (N = 16). Therapy teams trained in bCBCT and MDMA-assisted therapy will deliver bCBCT combined with two MDMA sessions and two couple emotion focused integration sessions. PTSD symptom severity and relationship functioning outcomes will be evaluated. CONCLUSION: This is the first study to examine the efficacy of MDMA-assisted bCBCT for improving PTSD and relationship functioning among a sample of U.S. military veterans and their partners. This project could provide an opportunity to pilot a scalable model of treating PTSD within the Veterans Affairs healthcare system and leverage the benefits of MDMA for veterans with PTSD, as well as the downstream benefits to their partner on both individual and relationship functioning.

BACKGROUND: The prosocial compound ± 3,4-methylenedioxymethamphetamine (MDMA) is an amphetamine derivative that has shown promise as an adjunct to psychotherapy in the treatment of post-traumatic stress disorder. MDMA increases positive responses to social images, and it has been suggested that the ability of MDMA to positively bias social perception may underlie its therapeutic efficacy as a psychotherapy adjunct. However, the effect of the compound on affective responses to positive or negative social feedback has not been tested. AIMS: In this study, we aimed to test the effects of MDMA compared to placebo and the prototypical stimulant, methamphetamine (MA), on responses to positive and negative social feedback. METHODS: This was a double-blind, placebo-controlled, crossover trial (NCT03790618), comparing the effects of two doses of MDMA (0.75 mg/kg, 1.5 mg/kg) to both placebo and MA (20 mg) on responses to a personalized social feedback task, similar to a dating app, in healthy adult volunteers ages 18-40 (N = 36, 18 women, 18 men). RESULTS/OUTCOMES: The high dose of MDMA increased positive affective responses to social feedback. CONCLUSIONS/INTERPRETATIONS: These findings suggest one process by which MDMA may facilitate social connection. Further work is needed to understand how MDMA affects responses to more generalized types of social feedback and to understand these effects in clinical populations.

Elsey, James W. B., Wuestman, Vivi Anna F., and Fieten, Anouk
- Abstract
Background: Previous research has focused on risks associated with non-clinical MDMA use, contrasting short-sighted hedonistic motivations with negative long-term consequences. User perceptions may be more nuanced, incorporating numerous underexplored positive long-term effects. We aimed to: (1) Assess MDMA user perceptions regarding both positive and negative long-term effects, and (2) Generate a large, open dataset with correlates to explore for future research. Methods: 886 non-clinical MDMA users completed an online, opt-in survey, with self-reported measures of acute, subacute, and long-term effects, motivations, use context, and polydrug use. Results: User perceptions of MDMA's long-term effects were far more positive than negative. Respondents endorsed long-term increases in aesthetic appreciation, deeper social connections, and positive changes in life perspectives, among other positive outcomes. A minority of users reported negative effects (e.g. on concentration/memory and mood), which remain important. Long-term effects showed several correlations with acute effects and motivations, with use due to peer influence being repeatedly linked to lower positive and higher negative long-term effects. Conclusion: MDMA users report getting much more than a momentary high from taking the drug. A nuanced appreciation of user perceptions can inform drug safety communication, and advance our understanding of drug effects by highlighting targets for further investigation.

LSD (Drug) , *PSILOCYBIN , *MENTAL depression , *HALLUCINOGENIC drugs , *ECSTASY (Drug) - Abstract
Different study designs of psychedelic trials may impact the blinding and expectance, leading to biased treatment effects. This study aimed to examine the association between antidepressant efficacy and study designs in psychedelic trials. Six databases were systematically searched. Eligible trials were required to investigate the efficacy of psychedelics (psilocybin, lysergic acid diethylamide [LSD], 3,4-Methylenedioxymethamphetamine [MDMA], and ayahuasca) in adult patients with depressive symptoms. We only considered oral psychedelic-assisted therapy without concomitant use of antidepressants. The primary outcome was the change in depressive symptoms. There were five study designs of psychedelic trials, including non-active-drug-as-placebo, active-drug-as-placebo, waitlist-as-control, fixed-order, and pre-post designs. In non-active-drug -as-placebo design, psilocybin (k = 4, Hedges' g [g] = 0.87, 95 % confidence intervals[CIs] = 0.58 to 1.16) and MDMA (k = 2, g = 0.65, 95%CIs = 0.26 to 1.05) were associated with large and medium effect sizes, respectively. In active-drug-as-placebo design, both psilocybin (k = 2, g = 0.71, 95%CIs = −0.01 to 1.43) and MDMA (k = 3, g = 0.53, 95%CIs = −0.23 to 1.28) were not statistically significant. In pre-post single-arm (k = 3, g = 2.51, 95%CIs = 1.00 to 4.02) and waitlist-as-control (k = 1, g = 2.88, 95%CIs = 1.75 to 4.00) designs, psilocybin showed a large effect size of antidepressant effect. Ayahuasca also showed a large effect size in both pre-post (k = 2, g = 1.88, 95%CIs = 1.18 to 2.57) and non-active-drug-as-placebo (k = 1, g = 1.60, 95%CIs = 0.84 to 2.36) designs. LSD was associated with a significant antidepressant effect only in non-active-drug-as-placebo design (k = 1, g = 1.49, 95%CIs = 0.80 to 2.17) but not in active-drug-as-placebo design (k = 1, g = 0.44, 95%CIs = −0.90 to 1.78). The antidepressant effects of psychedelics may be overestimated in studies with pre-post single-arm, non-active-drugs-as placebo, and waitlist-control designs. Restricted sample size, difficulty with establishing blinding for participants, and over expectancy limit the estimation of the antidepressant effect of psychedelic-assisted therapy. • The antidepressant effects of psychedelics may be overestimated in studies with pre-post single-arm, non-active-drugs-as placebo, or waitlist-control designs. • In non-active-drug-as-placebo design, psilocybin, MDMA, and LSD were associated with better efficacy than placebo. • In active-drug-as-placebo design, psilocybin MDMA, and LSD were not significantly associated with better efficacy than placebo. • In meta-regression, we identified that the higher dose of psilocybin is associated with a better antidepressant effect.

Psychedelics, historically celebrated for their cultural and spiritual significance, have emerged as potential breakthrough therapeutic agents due to their profound effects on consciousness, emotional processing, mood, and neural plasticity. This review explores the mechanisms underlying psychedelics' effects, focusing on their ability to modulate brain connectivity and neural circuit activity, including the default mode network (DMN), cortico-striatal thalamo-cortical (CSTC) loops, and the relaxed beliefs under psychedelics (REBUS) model. Advanced neuroimaging techniques reveal psychedelics' capacity to enhance functional connectivity between sensory cerebral areas while reducing the connections between associative brain areas, decreasing the rigidity and rendering the brain more plastic and susceptible to external changings, offering insights into their therapeutic outcome. The most relevant clinical trials of 3,4-methylenedioxymethamphetamine (MDMA), psilocybin, and lysergic acid diethylamide (LSD) demonstrate significant efficacy in treating treatment-resistant psychiatric conditions such as post-traumatic stress disorder (PTSD), depression, and anxiety, with favorable safety profiles. Despite these advancements, critical gaps remain in linking psychedelics' molecular actions to their clinical efficacy. This review highlights the need for further research to integrate mechanistic insights and optimize psychedelics as tools for both therapy and understanding human cognition. [ABSTRACT FROM AUTHOR]

Humphreys, Keith, Todd Korthuis, P., Stjepanović, Daniel, and Hall, Wayne
- Abstract
Therapeutic claims about many psychedelic drugs have not been evaluated in any studies of even modest rigor. The science of psychedelic drugs is strengthening, however, making it easier to differentiate some promising findings amid the hype that suffuses this research area. Ketamine has risks of adverse side effects (e.g., addiction and cystitis), but multiple studies suggest it can benefit individuals with treatment-resistant depression. Other therapeutic signals from psychedelic drug research that merit rigorous replication studies include 3,4-Methylenedioxymethamphetamine (MDMA) for post-traumatic stress disorder (PTSD) and psilocybin for depression, end of life dysphoria, and alcohol use disorder. The precise mechanisms through which psychedelic drugs can produce benefit and harm are not fully understood. Rigorous research is the best path forward for evaluating the therapeutic potential and mechanisms of psychedelic drugs. Policies governing the clinical use of these drugs should be informed by evidence and prioritize the protection of public health over the profit motive. [ABSTRACT FROM AUTHOR]

Cohen, I. Glenn and Marks, Mason
- Abstract
Research on psychedelic medicines is experiencing a revival. Some clinicians, scientists, and ethicists believe that psychedelics are so different from other treatments that they warrant special consideration in how they are researched, regulated, commercialized, and administered. Others argue that psychedelic medicines show clinical potential, but they should be treated like other medical interventions. In other words, identical standards should apply. This article analyzes whether psychedelic medicines warrant special consideration from a regulatory and ethical perspective. [ABSTRACT FROM AUTHOR]

Surface‐enhanced Raman spectroscopy (SERS) was utilized to measure low‐level fentanyl concentrations mixed in common cutting agents, cocaine, 3,4‐methylenedioxymethamphetamine (MDMA), methamphetamine, and caffeine. Mixtures were prepared with a fentanyl concentration range of 0–339 μM. Data was initially analyzed by plotting the area of a diagnostic peak (1026 cm−1) against concentration to generate a calibration model. This method was successful with fentanyl/MDMA samples (LOD 0.04 μM) but not for the other mixtures. A chemometric approach was then employed. The data was evaluated using principal component analysis (PCA), partial least squares (PLS1) regression, and linear discriminant analysis (LDA). The LDA model was used to classify samples into one of three designated concentration ranges, low = 0–0.4 mM, medium = 0.4–14 mM, or high >14 mM, with fentanyl concentrations correctly classified with greater than 85% accuracy. This model was then validated using a series of "blind" fentanyl mixtures and these unknown samples were assigned to the correct concentration range with an accuracy >95%. The PLS1 model failed to provide accurate quantitative assignments for the samples but did provide an accurate prediction for the presence or absence of fentanyl. The combination of the two models enabled accurate quantitative assignment of fentanyl in binary mixtures. This work establishes a proof of concept, indicating a larger sample size could generate a more accurate model. It demonstrates that samples, containing variable, low concentrations of fentanyl, can be accurately quantified, using SERS. [ABSTRACT FROM AUTHOR]

Background and Aims: Illicit drug consumption is associated with public health effects and criminal activities. This study aimed to estimate Illicit drug consumption and annual market in the Netherlands from wastewater analysis of drug residues. Methods: Residues of cocaine, amphetamine and 3,4‐methylene dioxymethamphetamine (MDMA) were measured between 2015 and 2022 in 30 Dutch wastewater treatment plants serving both rural and urban populations. These wastewater treatment plants covered 20% of the total Dutch population. The Dutch annual retail market was estimated by extrapolating consumption to the total Dutch population, back‐calculating consumption volume, correcting for drug purity and street price collected in voluntary checking services, and accounting for the correlation of consumption and urbanity. Results: The per capita MDMA and cocaine consumption correlated positively with the urbanity of the wastewater treatment plant catchments with r2 of 31% and 64%, respectively. Amphetamine did not show a significant correlation with urbanity. The three studied drugs were conservatively estimated to cover an average annual market value of 903 (95% prediction interval 829 to 987) million Euro for the studied period. Market estimations from prevalence figures and interceptions of international trade were similar. Conclusions: Illicit drug consumption in the Netherlands appears to correlate positively with urban (in contrast to rural) areas. Wastewater analysis can be used to estimate the volume and monetary value of illicit drug markets as a proof of concept. [ABSTRACT FROM AUTHOR]

MDMA (i.e., 3,4-methylenedixoymethamphetamine), commonly known as "Ecstasy" or "Molly," has been used since the 1970s both in recreational and therapeutic settings. The Food and Drug Administration (FDA) designated MDMA-Assisted Therapy (MDMA-AT) as a Breakthrough Therapy for posttraumatic stress disorder (PTSD) in 2017, and the FDA is requiring an additional phase 3 trial after rejecting the initial New Drug Application in 2024. Unlike other psychedelics, MDMA uniquely induces prosocial subjective effects of heightened trust and self-compassion while maintaining ego functioning as well as cognitive and perceptual lucidity. While recreational use in nonmedical settings may still cause harm, especially due to adulterants or when used without proper precautions, conclusions that can be drawn from studies of recreational use are limited by many confounds. This especially limits the extent to which evidence related to recreational use can be extrapolated to therapeutic use. A considerable body of preliminary evidence suggests that MDMA-AT delivered in a controlled clinical setting is a safe and efficacious treatment for PTSD. After a course of MDMA-AT involving three MDMA administrations supported by psychotherapy, 67%–71% of individuals with PTSD no longer meet diagnostic criteria after MDMA-AT versus 32%–48% with placebo-assisted therapy, and effects endure at long-term follow-up. This review primarily aims to distinguish evidence of recreational use in nonclinical settings versus MDMA-AT using pharmaceutical-grade MDMA in controlled clinical settings. This review further describes the putative neurobiological mechanisms of MDMA underlying its therapeutic effects, the clinical evidence of MDMA-AT, considerations at the level of public health and policy, and future research directions.

Byrska, Bogumiła and Stanaszek, Roman
- Abstract
Purpose: The most commonly associated substance found in Ecstasy tablets is MDMA (3,4-methylenedioxymethamphetamine). In our study, we showed how the composition of psychoactive ingredients in Ecstasy tablets seized on the drug market in Poland has changed in the years 2005–2020. Methods: The study material consisted of nearly 20,000 single Ecstasy tablets seized by representatives of law enforcement (the police, prosecutors) from 2005 to 2020 and analysed by the Institute of Forensic Research, Krakow, Poland. The analysis of the tablets was carried out by gas chromatography—mass spectrometry (GC–MS), high-performance liquid chromatography with diode array detection (HPLC–DAD) and ultra-high-performance liquid chromatography with photodiode array detection (UHPLC-PDA). Results: Currently, new types of MDMA tablets are introduced onto the market, available in various colours and shapes. Our study showed that tablets sold on the street as Ecstasy have variable purity and sometimes contain little or no MDMA. The mean content of MDMA in one tablet seized in 2005–2011 decreased from 90 to 50 mg. In 2013, Ecstasy tablets with a very high MDMA content (average 195 mg per tablet) appeared on the market, but in the next 2 years, the MDMA content decreased again. From 2016, the average MDMA content began to rise again, ranging from 60 to 280 mg. Conclusion: Tablets sold as Ecstasy also contained completely different psychoactive substances, including new psychoactive substances (NPS) (found in almost 20% of all examined tablets sold as Ecstasy) belonging to different chemical groups or their dangerous combinations (i.e. phenylethylamines, piperazines, tryptamines, cathinones, arylalkylamines, arylcyclohexylamines and piperidines). Such a large variety of psychoactive substances in Ecstasy tablets is associated with a high risk for users unaware of their composition. [ABSTRACT FROM AUTHOR]

Psychoactive drugs such as alcohol and stimulants are typically used in social settings such as bars, parties or small groups. Yet, relatively little is known about how social contexts affect responses to drugs, or how the drugs alter social interactions. It is possible that positive social contexts enhance the rewarding properties of drugs, perhaps increasing their potential for repeated use and abuse. In addition, drugs may enhance the rewarding effects of social interactions by increasing feelings of social closeness and connectedness. To examine these relations, we investigated the effects of several drugs (MDMA, methamphetamine, alcohol) on feelings of connection between two strangers engaged in a conversation. We also investigated feelings of connection between two participants who discussed either 'shallow' or deeper topics in two conversations, without any drugs. All four conditions: deeper conversations, MDMA, methamphetamine and alcohol significantly increased feelings of connection and closeness compared with control conditions (small talk or placebo). We postulate that these feelings of connection could contribute to the drugs' rewarding effects when the drugs are used in social contexts. [ABSTRACT FROM AUTHOR]

Background: There is ongoing research into the potential use of psychedelics and 3,4-methylenedioxy-methamphetamine (MDMA) as alternatives to commonly used medications for treating major depressive and anxiety disorders. Aims: We aimed to assess the efficacy of psychedelics and MDMA in managing depressive and anxiety symptoms and evaluate their safety profiles. Methods: We searched five databases for randomized controlled trials of psychedelics and MDMA targeting depressive and anxiety symptoms and conducted a meta-analysis using a random effects model when possible. The review protocol is registered in PROSPERO under CRD42022341325. Results: Psilocybin induced a rapid and sustained reduction in depressive and anxiety symptoms in patients with major depressive disorder and in patients with life-threatening cancer. MDMA induced a decrease in depressive symptoms in patients with life-threatening cancer, autism spectrum disorder, and post-traumatic stress disorder. MDMA's effect size was either negligible or negative in reducing generalized anxiety symptoms, but MDMA reduced social anxiety symptoms. Ayahuasca induced a reduction in depressive symptoms in individuals with treatment-resistant major depressive and personality disorders. Lysergic acid diethylamide (LSD) induced a decrease in anxiety symptoms in individuals with life-threatening cancer. Psilocybin's adverse effects were noticeable for elevated blood pressure, headaches, and panic attacks. For MDMA, elevated blood pressure, headaches, panic attacks, and feeling cold were noticeable. Conclusions: Psychedelics (psilocybin, ayahuasca, and LSD) and MDMA have the potential to induce a reduction in depressive and anxiety symptoms. Adverse effects are noticed. Rigorous randomized controlled studies with larger sample sizes utilizing instruments with better reliability and validity are warranted. [ABSTRACT FROM AUTHOR]

3,4-Methylenedioxymethamphetamine (MDMA) is being investigated in controlled clinical trials for use as an adjunct medication treatment for post-traumatic stress disorder. MDMA is metabolized by N-demethylation, primarily by CYP2D6, to its main inactive metabolite, 4-hydroxy-3-methoxymethamphetamine. It is also metabolized to a lesser extent by CYP1A2, CYP2B6, and CYP3A4 to its active metabolite, 3,4-methylenedioxyamphetamine. Considering the extensive hepatic metabolism and excretion, MDMA use in psychiatry raises concerns over drug-induced liver injury (DILI), a rare but dangerous event. Majority of the drugs withdrawn from the market for liver injury caused death or transplantation at frequencies under 0.01%. Unfortunately, markers for liver injury were not measured in most published clinical trials. At the same time, no visible DILI-related symptoms and adverse events were observed. Idiosyncratic DILI cases are rarely registered during clinical trials due to their rare nature. In this study, we surveyed a larger, over 1,500, and a more diverse set of reports from the FDA Adverse Event Reporting System and found 23 cases of hepatic injury and hepatic failure, in which MDMA was reported to be taken in addition to one or more substances. Interestingly, 22 out of 23 cases had one or more listed drugs with a known DILI concern based on the FDA's DILIrank dataset. Furthermore, only one report had MDMA listed as the primary suspect. Considering the nearly 20 million doses of MDMA used annually, this single report is insufficient for establishing a significant association with DILI.

Abstract Psychedelic-assisted therapy (PAT) with substances like psilocybin and MDMA has shown promise for conditions including depression and post-traumatic stress disorder. Psilocybin and MDMA may become approved medicines in the coming decade. This study assessed knowledge and attitudes regarding PAT among 879 U.S. healthcare professionals via anonymous online survey. Multivariable linear regression was used to identify predictors of openness to clinical use. Most participants (71.2%) were female and White (85.8%), with a mean (SD) age of 45.5 (12.7) years. Registered nurses (25.4%) and physicians (17.7%) comprised the largest professional groups. Respondents endorsed strong belief in therapeutic promise, and moderate openness to clinical use and support for legal access to both substances, with higher overall ratings for psilocybin compared to MDMA.

Abstract As clinical trials for psychedelics move into phase III in the USA, Europe must address its lag in integrating professional education around psychedelic-assisted therapy (PAT) and supporting psychedelic drug research. This paper evaluates the necessary frameworks for implementing PAT in Germany, emphasizing the nation’s potential leadership role within the European Union. With Australia having already approved MDMA and psilocybin for mental health indications, the Ukrainian government exploring MDMA treatment for war-related PTSD, and initial clinical trials involving MDMA and LSD with patients in Switzerland which restarted the restricted medical use of these substances around 2014, the medical authorization of psychedelics in these countries establishes precedent showcasing both the promise and challenges of researching and implementing PAT in nations where the substances were formally scheduled as illicit substances. Key challenges include establishing rigorous standards for practitioner training, accessibility, and defining regulatory oversight. This paper focuses on the development of robust infrastructure in Germany, which will support the roll out of PAT, and details ethical considerations, training protocols, and governmental roles in the formulation of treatment frameworks. This approach aims not only to guide Germany in adopting PAT but also to influence broader European policy, ensuring that patients receive ethically sound and proficient care. The findings suggest pathways for Europe to reclaim its historical lead in psychiatric and therapeutic innovation.

Studies of psychedelic-assisted therapy with LSD, psilocybin, MDMA, and related substances show clinical promise but inadequately assess side effects. Measuring side effects is challenging because they are not always easily differentiated from treatment effects or disease symptoms and show high heterogeneity, variable duration and impact, and sensitivity to context. A systematic questionnaire describing important characteristics of side effects of psychedelics and MDMA would greatly improve on previous methods. We aimed to create a standardized tool for recording clinically relevant side effects of psychedelics and MDMA, including their severity, duration, impact, and treatment-relatedness. We constructed the Swiss Psychedelic Side Effects Inventory (SPSI) based on insights from previous research. It was pilot tested in 145 participants from three studies. Structured feedback from an expert panel was used to improve validity and feasibility. The final SPSI contains 32 side effects and standardized follow-up questions about their severity, impact, treatment-relatedness, and duration. It is compatible with any study design and can be administered as an interview or self-report at any timepoint after treatment with psychedelics or MDMA. The SPSI omits relatively unimportant side effects for brevity's sake, though space for additional symptoms is given. Future studies are needed to confirm its validity in different contexts. The SPSI is available in English and German for collecting systematic data on side effects from psychedelics and MDMA. This information is vital for improving clinical decisions, informed consent, and patient safety. • Psychedelics and MDMA can cause a unique profile of side effects which are not well-captured by the methods used in previous studies. • Psychedelic side effects vary in their severity, duration, and subjective impact. • Using previous studies, pilot data, and expert feedback, we developed the Swiss Psychedelic Side Effects Inventory (SPSI). • The SPSI contains 32 side effects and assesses their severity, impact, duration, and treatment-relatedness. • The SPSI can be used at any timepoint after psychedelic administration in any study of psychedelics or MDMA.

- Abstract
Psychedelic-assisted therapy (PAT) with substances like psilocybin and MDMA has shown promise for conditions including depression and post-traumatic stress disorder. Psilocybin and MDMA may become approved medicines in the coming decade. This study assessed knowledge and attitudes regarding PAT among 879 U.S. healthcare professionals via anonymous online survey. Multivariable linear regression was used to identify predictors of openness to clinical use. Most participants (71.2%) were female and White (85.8%), with a mean (SD) age of 45.5 (12.7) years. Registered nurses (25.4%) and physicians (17.7%) comprised the largest professional groups. Respondents endorsed strong belief in therapeutic promise, and moderate openness to clinical use and support for legal access to both substances, with higher overall ratings for psilocybin compared to MDMA. Objective knowledge items revealed low knowledge of therapeutic uses, risks, and pharmacology. Primary concerns were lack of trained providers, financial cost, and potential contraindications. Prior psychedelic use, self-rated knowledge, younger age, and professional role predicted openness to clinical use of psilocybin and MDMA, with physicians reporting lower openness. As psychedelics continue to garner popular and scientific interest, results indicate a pressing need for additional formal training to provide balanced, evidence-based information from trusted sources.

Background: The substitution of cannabis for alcohol and other drugs has been conceptualised in a harm reduction framework as where cannabis is used to reduce the negative side-effects, addiction potential, and social stigma of other drugs. There is currently mixed evidence with recent reviews suggesting cannabis co-use patterns may vary by age and ethnicity. Yet few studies have had large enough samples to examine this demographic variation in detail. Aims: To explore the co-use of cannabis with alcohol and other drugs within demographic subgroups of a large sample of people who use cannabis. Specifically: (1) whether cannabis is being substituted for other drugs, and (2), whether cannabis use leads to more, less or the same level of other drug use. Method: Online convenience survey promoted via Facebook™ completed by 23,500 New Zealand respondents. Those who had used cannabis and any of eight other substances in the same six-month period were asked if their use of cannabis had any impact on their use of each other substance ("a lot more", "little more", "no impact/same", "little less", "a lot less"). Frequency and quantity used of each other drug was compared by co-use group. Generalised logistic regression models were developed to predict co-use categories. Results: Significant proportions reported cannabis use led to "less" alcohol (60%), synthetic cannabinoid (60%), morphine (44%) and methamphetamine (40%) use. Those who reported using "less" had lower frequency and amount used of other drugs. Approximately seven-out-ten reported cannabis use had "no impact" on LSD, MDMA, and cocaine use. One-in-five reported using cannabis led to "more" tobacco use. Young adults (21–35-years) were more likely to report cannabis use led to "less" drinking and methamphetamine use. Adolescent co-users (16–20 years) reported mixed impacts. Māori were more likely to report cannabis use resulted in "less" alcohol, tobacco, methamphetamine, and LSD use. Students and those living in cities were less likely to report cannabis use lowering use of other substances. Conclusion: Cannabis and other drug co-use patterns are moderated by life stages, lifestyles, cultural perspectives, and urbanicity. Harm reduction initiatives and policy reforms should take account of these moderating factors. [ABSTRACT FROM AUTHOR]

Introduction Methods Results Discussion and Conclusions This study explores the attitudes of psychologists towards psychedelics and psychedelic‐assisted therapy (PAT) following the world‐first regulatory changes in 2023 in Australia which permitted psilocybin and 3,4‐methylenedioxy‐methamphetamine (MDMA) to be used in clinical services.A purposive sample of 20 Australian psychologists was recruited using snowball sampling. Semi‐structured interviews were conducted which explored participants' attitudes, knowledge and concerns about PAT. Data were coded and analysed to identify and develop theme categories.Most psychologists exhibited positive attitudes towards psychedelics and their therapeutic potential, viewing them as promising for addressing chronic mental health conditions like depression. However, there was a notable concern regarding the limited evidence on efficacy and potential adverse experiences, as well as the complexity of the individualised treatment protocol. Despite enthusiasm, many psychologists had limited detailed knowledge about the interventions themselves. The need for comprehensive education and training programs, including exposure to psychedelic experiences and credible higher education institutions, was emphasised to ensure competence in administering PAT.Psychologists displayed notably positive attitudes towards PAT, likely reflecting both shifting perceptions of psychedelics and self‐selection bias within the sample. Despite this optimism, concerns were raised about psychiatric risks and the necessity for comprehensive and reputable training and supervision. The cohort showed openness to both novel treatments and innovative training methods, underscoring the importance of enhancing educational frameworks to ensure effective implementation of PAT.

3,4-Methylenedioxymetamphetamine(MDMA)-assisted psychotherapy (MDMA-AP) is a proposed treatment for posttraumatic stress disorder (PTSD) that may be approved for adults soon. PTSD is also common among trauma-exposed adolescents, and current treatments leave much room for improvement. We present a rationale for considering MDMA-AP for treating PTSD among adolescents. Evidence suggests that as an adjunct to therapy, MDMA may reduce avoidance and enable trauma processing, strengthen therapeutic alliance, enhance extinction learning and trauma-related reappraisal, and hold potential beyond PTSD symptoms. Drawing on existing trauma-focused treatments, we suggest possible adaptations to MDMA-AP for use with adolescents, focusing on (1) reinforcing motivation, (2) the development of a strong therapeutic alliance, (3) additional emotion and behavior management techniques, (4) more directive exposure-based methods during MDMA sessions, (5) more support for concomitant challenges and integrating treatment benefits, and (6) involving family in treatment. We then discuss potential risks particular to adolescents, including physical and psychological side effects, toxicity, misuse potential, and ethical issues. We argue that MDMA-AP holds potential for adolescents suffering from PTSD. Instead of off-label use or extrapolating from adult studies, clinical trials should be carried out to determine whether MDMA-AP is safe and effective for PTSD among adolescents.

BACKGROUND: Neurorehabilitation in military populations is complicated by higher rates of PTSD and unique characteristics of military institutions. These factors can adversely impact the patient-therapist therapeutic alliance and engagement with the rehabilitation process leading to poorer outcomes. MDMA is a non-classical psychedelic with pro-social and fear regulating properties. MDMA-assisted therapy is being explored as a novel treatment for PTSD that potentially offers rapid symptom improvement and enhances therapeutic alliance. OBJECTIVE: A review of MDMA-assisted therapy for PTSD is provided in the context of neurorehabilitation in military populations. The molecular mechanism of MDMA is outlined and a novel application of MDMA for neurorehabilitation is proposed. METHODS: This is an expert review and synthesis of the literature. RESULTS: Results from late-stage clinical trials suggest MDMA-assisted therapy for PTSD would be of particular benefit for military populations with PTSD. The unique pro-social properties of MDMA could be leveraged to enhance the therapeutic alliance and patient engagement during neurorehabilitation. CONCLUSION: The unique qualities and benefits of MDMA and MDMA-assisted therapy for PTSD suggest relevant application in military personnel undergoing neurorehabilitation. There are many similarities in patient-therapist dynamics in PTSD treatment and neurorehabilitation. The properties of MDMA which enhance therapeutic alliance, downregulate fear, and increase cognitive flexibility would potentially benefit both military personnel with and without PTSD undergoing neurorehabilitation.

3,4-methylenedioxymethamphetamine (MDMA) assisted therapy has been shown to be a safe and effective treatment for PTSD and emerging research suggests a change in personality traits may be a factor in treatment response. Most prior research on MDMA and personality has focused on cross-sectional comparisons of MDMA users and non-users; as such, well-controlled research assessing personality and affective states
change following MDMA vs placebo administration is needed. In the current pre-registered study, we investigated the impact of MDMA administration on five-factor model (FFM) traits and affective states before and 48 h after drug administration in a randomized, placebo-controlled study of healthy adults (N = 34). Statistical significance was not observed for the four a priori hypotheses; however, medium effect sizes were found between MDMA administration and trait Openness and Positive Affect 48 h following drug administration, compared to placebo (d = .79 and .51, respectively). This study provides initial results to help guide future well-powered studies with large samples and longer follow-up timepoints to continue to investigate how MDMA impacts personality and emotional experience, which may inform optimization of MDMA treatment approaches.

Objective: Despite rapid advances in psychedelic sciences and the increasing number of countries legalizing psychedelics for the treatment of mental illnesses, the attitudes, knowledge and readiness of both mental health consumers and the general population remain largely unknown. Methods: A cross-sectional survey was conducted among Australians, targeting individuals with mental illness as potential mental health service users. A sub-sample of individuals free of mental illness was also surveyed to assess attitudes in the general population. Participants completed the Attitudes on Psychedelics Questionnaire, the Basic Knowledge of Psychedelics Test and a questionnaire by Corrigan et al. to capture attitudes toward psychedelic therapy by mental health service users. Results: Of the 502 respondents, 64.5% self-identified as having a mental illness. A significant proportion favored legalizing psychedelics for medical use (43%) and were open to their use (52.4%), yet fewer viewed their effects positively (24%) or considered them safe (33%). Most participants reported to be psychedelic naive (61%). Participants with mental illness had significantly more experience with psychedelics than participant free of mental illness (44.1% vs 29.7%). Experience, perceived knowledge and actual knowledge significantly predicted attitudes toward legalization, effects, risks and openness to psychedelics. Conclusions: While a large proportion of Australians are in favor of legalizing psychedelics for medical purposes, concerns about safety remain. People with self-identified mental illness, those with previous recreational psychedelic experience and those with greater knowledge of psychedelics were more likely to have positive attitudes toward psychedelics and psychedelic-assisted therapy.

Substance use/abuse and suicide are two closely related phenomena, mostly due to neurobiological, psychological, and social impairments. In the present narrative review, the relationship between suicidal behavior (SB) and the use and abuse of common recreational drugs, such as alcohol, cannabis, cocaine, methamphetamine, heroin, nicotine, ketamine, psilocybin, MDMA, and LSD, has been explored. Furthermore, potential mechanisms linking the two have also been examined. According to current research, all substances appear to have a deleterious effect on SB except for ketamine and psilocybin, which could potentially confer a protective effect. Further studies are needed to understand the relationship between MDMA, LSD, and suicide. [ABSTRACT FROM AUTHOR]

Although effective evidence-based trauma-focused psychotherapies for posttraumatic stress disorder (PTSD) are available, a significant proportion of patients show a suboptimal response or do not complete them. MDMA-assisted therapy (MDMA-AT) for PTSD is a promising intervention currently being evaluated in numerous studies worldwide, including investigation for potential Food and Drug Administration (FDA) approval in the United States. The concepts of set and setting are foundational in psychedelic therapy and refer to the mindset a person brings to therapy and the environment in which it takes place, respectively. Both are believed to play a critical role in the individual’s experience and efficacy of MDMA-AT. In this article, we describe the importance of set and setting in MDMA-AT for PTSD and outline the advantages and challenges of implementing this novel intervention in large healthcare settings such as the Veterans Health Administration (VHA). Mostly derived from our experience conducting clinical trials of MDMA-AT for PTSD in VHA, we present specific and practical suggestions for optimizing set and setting from both the participant’s and clinician’s perspective in a manner that both leverages the opportunities of such settings and adapts to their challenges. These recommendations are intended to inform future MDMA-AT for PTSD research and, potentially, eventual clinical implementation efforts in traditional healthcare systems.

3, 4-methylenedioxyamphetamine (MDMA) has gained significance over the years, especially at rave festivals, as a recreational drug for its noted effects in mood enhancement and autonomic stimulation. While these effects have been noted, severe adverse outcomes, and even death, following the ingestion of MDMA have been recorded.We present a 35-year-old male who ingested the drug at the Electric Daisy Carnival (EDC), the largest electronic dance music festival in North America as of 2024 [1]. Every year, many young adults are brought to local hospitals from the festival for drug overdoses, hyperthermia, and dehydration. At the festival, the patient was witnessed to have a seizure, presented with altered mental status and deemed hyperthermic at 109 degrees Fahrenheit. For these reasons, he was rapidly intubated and submerged in an ice bath at the festival’s medical tent. At the county hospital, the patient was diagnosed with multiorgan failure, cerebrovascular ischemia, and coagulopathy. He received life-saving treatment such as continuous renal replacement therapy as well as intubation for acute hypoxemic respiratory failure. MRI of the brain showed central- embolic infarcts and the patient was closely monitored in the intensive care unit (ICU) for eight days. After twenty days of inpatient treatment, the patient was discharged. He was discharged with his mental status at baseline and without gross neurologic deficits. A permacath was placed for hemodialysis to be continued outpatient.This case report highlights the importance of prompt medical management which can be crucial for patient survival following a life-threatening overdose with MDMA. It also exemplifies the need for increasing social awareness regarding the severe and detrimental outcomes an MDMA overdose can cause as this drug continues to be widely used in the setting of rave and music festivals.

Introduction: The positive results of MDMA from Phase 2 and 3 clinical trials in MDMA-assisted therapy (MDMA-AT) for the treatment of post-traumatic stress disorder (PTSD) call for a critical evaluation of its regulatory status within the European mental healthcare system. This is driven by the recent submission of MDMA-AT for FDA approval in the United States. Unless coordinated efforts in the European regulatory landscape start, there may be potential divergences in national regulatory strategies. Gaining insights from researchers and clinicians involved in the application of MDMA-AT may be useful in guiding the discussion of factors involved in its implementation.Method: A comprehensive invitation-only survey was sent to researchers and clinicians involved in MDMA-AT clinical trials and contributors to the scientific literature on MDMA-AT from around the globe. This study aimed to collect opinions on clinical practices, training, and regulation worldwide, examining the global best practices and pitfalls to outline strategies for possible European implementation of MDMA-AT.Results: The survey, which included responses from 68 experts, yielded a range of opinions where a large majority endorsed the need for training and standardization, emphasizing equity and access, stressing impediments in the national approval processes, and reflecting critically on anticipated spill-over effects of MDMA-AT in clinical settings.Conclusion: The experts highlight the need for science-informed policy development, active regulatory involvement, and international cooperation to incorporate MDMA-AT into the European mental healthcare system in general and the treatment of PTSD in particular. The study emphasizes the importance of ongoing research, open professional discourse, and collaborative engagement to facilitate MDMA-AT's ethical and effective implementation.

Abstract Classic psychedelics and MDMA have a colorful history of recreational use, and both have recently been re-evaluated as tools for the treatment of psychiatric disorders. Several studies have been carried out to assess potential long-term effects of a regular use on cognition, delivering distinct results for psychedelics and MDMA. However, to date knowledge is scarce on cognitive performance during acute effects of those substances. In this systematic review and meta-analysis, we investigate how cognitive functioning is affected by psychedelics and MDMA during the acute drug effects and the sub-acute (“afterglow”) window. Our quantitative analyses suggest that acute cognitive performance is differentially affected by psychedelics when compared to MDMA: psychedelics impair attention and executive function, whereas MDMA primarily affects memory, leaving executive functions and attention unaffected. Our qualitative analyses reveal that executive functioning and creativity may be increased during a window of at least 24 h after the acute effects of psychedelics have subsided, whereas no such results have been observed for MDMA. Our findings may contribute to inform recommendations on harm reduction for recreational settings and to help fostering differential approaches for the use of psychedelics and MDMA within a therapeutic framework.

DRUGS of abuse , *RAMAN spectroscopy , *MUSIC festivals , *CONTROLLED substances , *DRUG abuse - Abstract
Ecstasy tablets, a type of common street drug originally consisting of 3,4‐methylenedioxymethamphetamine (MDMA), provide stimulant and hallucinogen psychoactive effects. They are frequently found in nightclubs, musical festivals or other recreational events believed to create a relaxing experience for the users. From a forensic perspective, when the drug of abuse is suspected in such scenarios, the law enforcement personnel would then require an easy‐to‐perform, quick and accurate method to detect the existence of such controlled substance prior to the seizure and subsequent forensic examination. In this study, we assessed the performance of a portable Raman spectroscopy as the primary aid in determining ecstasy tablets at the point of use. A total of 130 ecstasy tablet samples were analysed by Raman spectroscopy and characterised by gas chromatography–mass spectrometry (GC–MS). Active chemical substances and cutting agents detected by the two instrumentations were then compared. The performance of Raman spectroscopy was further assessed in terms of its accuracy, sensitivity and specificity, corresponding to the analysis results obtained from GC–MS analysis. Overall, portable Raman Spectroscopy used in this study shows an accuracy of 85.4% in analysing ecstasy tablets obtained from case samples, while the sensitivity and specificity were determined as 85.2% and 100%, respectively. No false positives for MDMA or other drugs were reported. Our results show that portable Raman spectroscopy is a suitable technique for targeted determination of the presence of ecstasy tablets, especially in forensic cases that require non‐destructive, rapid and mass screening during on‐site testing by law enforcement personnel.

The PRIDE National Drug Use survey for grades 7–12 was administered to youth in their school classrooms. Results indicated that male students, 9th–12th grade students, non-Caucasian students, and employed students were at highest risk for ecstasy use. In addition, students with low involvement in protective factors (participation in community activities, school activities and clubs, sports, faith-based institutions, and getting good grades), parent factors, teacher factors and school factors, and high involvement in risk factors (taking part in gang activity, friend's use of drugs, access to substances, and getting into trouble at school or with the law) were more likely to use this substance. These findings should be considered when developing programs to prevent ecstasy use among youth. [ABSTRACT FROM AUTHOR]

3,4-Methylenedioxymethamphetamine (MDMA) is a synthetic amphetamine derivative with notable psychoactive properties and emerging therapeutic potential, particularly for treating post-traumatic stress disorders (PTSD) and substance use disorders. However, its use remains controversial due to inter-individual variability influenced by both environmental and genetic factors. In this context, pharmacogenomics could play a crucial role in guiding MDMA treatment by identifying individuals with genetic predispositions affecting their response to MDMA. Tailoring treatment plans based on individual's genetic makeup may enhance therapeutic outcomes and minimize adverse effects, leading to safer and more effective use of MDMA in clinical settings. Literature analysis reveals that the influence of genetic variants within genes encoded for enzymes involved in MDMA metabolism and/or pharmacodynamics (PD) targets have been relatively under-investigated in humans. Some studies have pointed out associations between MDMA-induced effects and polymorphisms. For example, the catechol-O-methyltransferase (COMT) Val158Met polymorphism has been associated with cognitive and cardiovascular MDMA-induced effects. Similarly, polymorphisms in the serotonin-linked promoter region (5HTTLPR) have been associated with several MDMA-induced adverse effects including mood disorders. However, despite these findings, only a few associations have been highlighted. Furthermore, some genes encoded for MDMA targets have been only poorly investigated, representing a significant research gap. These observations underscore the need for large-scale, controlled pharmacogenomics studies focusing on a broad panel of genes involved into MDMA pharmacokinetics and PD. Such studies could provide critical insights for optimizing MDMA's therapeutic use and minimizing its risks. [ABSTRACT FROM AUTHOR]

The phenylethylamine, 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy'), is the prototypical example of an entactogen. Its original placement in highly restrictive drug usage categories in the US and UK, led to an inevitable restriction on MDMA neuroscience research and treatment. The dominant pharmacological effects of MDMA are its properties of release and inhibition of reuptake of amine neurotransmitter transporters for dopamine, norepinephrine, and serotonin. MDMA is an agonist of a wide range of receptors; its mood-altering effects are mediated via 5-HT2A receptors; this receptor may also mediate its effects on body temperature, analgesia, and anxiolytic properties. The mechanisms underlying MDMA's entactogenic properties of sociability and interpersonal closeness are not known but release and involvement of oxytocin, a peptide thought by some to be involved in social bonding, has been suggested. Adverse effects of MDMA are mostly transient; acute multiorgan adverse effects occurring during raves or crowded dance gatherings include dehydration, hyperthermia, seizures, rhabdomyolysis, disseminated intravascular coagulation, and acute renal failure. Deaths following MDMA taken by itself are rare compared to fatalities following coadministration with other drugs. A recent FDA-approved phase 3 clinical trial of MDMA for post-traumatic stress disorder (PTSD) led to the conclusion that MDMA-assisted therapy represents a potential breakthrough treatment meriting expedited clinical evaluation. Despite the ongoing deliberations by the FDA and EMA for approval of MDMA treatment of PTSD, the Australian Therapeutic Goods Administration (TGA) recently announced that after an evaluation of the therapeutic value, benefits, and risks of MDMA, it will permit its prescribing for the treatment of PTSD. Further examples of regulatory relaxation toward MDMA-assisted psychotherapy are underway. These include the FDA's recently approved clinical trial to assess MDMA's efficacy in the treatment of "asociality" in patients with schizophrenia and an open trial of MDMA treatment for alcohol-use disorder which showed decreased alcohol consumption. There are also ongoing studies on the little understood startle response, anxiety associated with life-threatening illness, and social anxiety in autistic adults. [ABSTRACT FROM AUTHOR]

Science on methylenedioxymethamphetamine (MDMA) and MDMA-like substances is faced with the unique situation that this class of psychoactive agents is referred to with two basic names for its effects on the mind: empathogens and entactogens. Empathogen usually refers to the prosocial, empathetic, and openness properties of MDMA, while entactogen usually refers to the introspective and self-awareness properties of this substance. We review the origin and usage of the two terms, and also review recent findings that support that MDMA is an empathogen and an entactogen. Mostly no specified reasons can be detected whether research groups employ the term "entactogenic," "empathogenic," both, or neither, in their publications. A case is made that the use of two basic names for the effects on the mind for the same class of psychoactive substances is not warranted because a holistic principle underlies empathogenic and entactogenic properties of MDMA: an intense feeling of connection. Entactogenic characterizes being deeply connected to oneself, and empathogenic being deeply connected to others. We therefore suggest the name connectogen as the new basic name for the mind effects of MDMA and MDMA-like substances, a term having the connotation of producing a joining together/producing a connection. Thus, MDMA is basically a connectogen with at least the two major connective properties: entactogenic (intrapersonal) and empathogenic (interpersonal). Furthermore, first evidence shows that MDMA might also have further connectogenic properties such as a strong sense of connection with the here-and-now, the body, the world, and with spiritual principles. Finally, we compare connectogenic properties of MDMA with connectogenic properties of classic psychedelics, and lay out some future research in this regard. [ABSTRACT FROM AUTHOR]

- Abstract
Research suggests that hair color, hair dyeing, and perspiration can bias hair test results regarding drug exposure, but research is needed to examine such associations in a multivariable manner. In this epidemiology study, adults were surveyed entering nightclubs and dance festivals in New York City, and 328 provided hair samples, which were analyzed using ultra‐high‐performance liquid chromatography–tandem mass spectrometry to determine the level of detection of cocaine and 3,4‐methylenedioxymethamphetamine (MDMA). Reporting use was not an inclusion criterion for analysis. We used two‐part multivariable models to delineate associations of hair color, past‐year hair dyeing, and frequency of past‐month hat wearing (which may increase perspiration) in relation to any vs. no detection of cocaine and MDMA as well as level of detection, controlling for hair length, self‐reported past‐year cocaine/ecstasy/MDMA use, and age, sex, and race/ethnicity. Those reporting having dyed their hair were at increased odds of having any level of cocaine detected (adjusted odds ratio [aOR] = 3.75, 95% CI confidence interval [CI]: 1.85–6.70), and compared to those with brown hair, those with blond(e) hair on average had lower levels of cocaine (ng/mg) detected (beta = −7.97, p = 0.025). Those reporting having dyed their hair were at increased odds of having any level of MDMA detected (aOR = 3.05, 95% CI: 1.44–6.48), and compared to those who reported never wearing a hat, those who reported wearing a hat daily or almost daily on average had lower levels of MDMA (ng/mg) detected (beta = −6.61, p = 0.025). This study demonstrates the importance of using multivariable models to delineate predictors of drug detection. [ABSTRACT FROM AUTHOR]

- Abstract
A portable and highly sensitive sensor was designed for the specific detection of 3,4‐methyl‐enedioxy‐methamphetamine (MDMA), in a range of field‐testing situations. The sensor can detect MDMA in street samples, even when other controlled substances drugs, or adulterants are present. In this work, we report for the first time a sensor using electroactive molecularly imprinted polymer nanoparticles computationally designed to recognize MDMA and then produced using solid phase synthesis. A composite comprising chitosan, reduced graphene oxide, and molecularly imprinted polymer nanoparticles synthesized for MDMA for the first time was immobilized on screen‐printed carbon electrodes. The sensors displayed a satisfactory sensitivity (106.8 nA × μM−1), limit of detection (1.6 nM; 0.31 ng/mL), and recoveries (92–99%). The accuracy of the results was confirmed through validation using Ultra‐High Performance Liquid Chromatography coupled with tandem Mass Spectrometry (UPLC‐MS/MS). This technology could be used in forensic analysis and make it possible to selectively detect MDMA in street samples. [ABSTRACT FROM AUTHOR]

In the past few years, psilocybin, a psychedelic compound found in “magic mushrooms” (psilocybin mushrooms), has undergone decriminalization in numerous cities across the US and has been legalized in Oregon and Colorado. Proponents of psilocybin decriminalization have emphasized its therapeutic potential in treating mental health disorders. Furthermore, psilocybin mushrooms are considered the safest psychedelic option, with lower potency and a reduced risk of overdoses and emergency hospitalizations compared to other prevalent psychedelics, such as LSD (lysergic acid diethylamide) and MDMA (3,4-methylenedioxymethamphetamine). We analyzed the impact of psilocybin reforms on public interest in psilocybin, as well as their cross-commodity effects on LSD and MDMA, utilizing extensive web-based search data. We observe a significant increase in psilocybin search volume and a notable reduction in search volume associated with LSD and MDMA. Our results are consistent nationwide across states, irrespective of their stance on psilocybin reforms. The shift in public interest toward psilocybin, which is considered the safest psychedelic, away from LSD and MDMA, carries positive implications for public health. [ABSTRACT FROM AUTHOR]
