Introduction: Cannabis products containing delta-8-THC became widely available in most of the United States in late 2020 and rapidly became a significant source of revenue for hemp processing companies, especially in states where use of delta-9-THC remains illegal or requires professional authorization for medical use. Scientific research on the use of delta-8-THC is scarce, previous clinical studies included a combined total of 14 participants, leading some state governments to prohibit it until its properties and effects are better understood. Methods: Researchers developed an online survey for delta-8-THC consumers addressing a broad range of issues regarding delta-8-THC, including use for the treatment of health and medical conditions. Previous survey studies on the medical use of cannabis and cannabis products informed survey components. Results: Patterns of delta-8-THC use had both similarities with and differences from the use of delta-9-THC cannabis and products. Administration methods were primarily edibles (64%) and vaping concentrates (48%). About half of the participants (51%) used delta-8-THC to treat a range of health and medical conditions, primarily anxiety or panic attacks (69%), stress (52%), depression or bipolar disorder (46%), and chronic pain (41%). Participants compared delta-8-THC very favorably with both delta-9-THC and pharmaceutical drugs and reported substantial levels of substitution for both. Most participants did not inform their primary care provider of their delta-8-THC use (78%) and were not confident of their primary care provider's ability to integrate medical cannabis into their treatment (70%). Knowledge of effective dosages was low, and participants' knowledge of delta-8-THC was primarily from the Internet and their own experiences. Conclusion: Harm reduction is a central component of public health. Although the legal environment is becoming more restrictive for delta-8-THC in comparison to delta-9-THC, results suggest that delta-8-THC may be equally effective for desired purposes of cannabis use and lower in undesirable or adverse effects. All policies and practices should be informed by empirical evidence. Considerable research will be needed to systematically verify the patterns reported by participants, and collaborations among academic researchers, government, and the cannabis industry may be valuable in developing the knowledge base for delta-8-THC and other cannabinoids.

Identifying gaps and strengths in psychedelic-related knowledge is key to developing effective, evidence-based education to inform appropriate use of and harm reduction practices for psychedelics in the naturalistic use landscape. The current study piloted an assessment instrument with questions on legal status, therapeutic potential, and side effects of psychedelics among people reporting current psychedelic use. We recruited participants (

Introduction: Many health care providers would benefit from greater knowledge and awareness of medical cannabis, even if they choose not to integrate it into their medical practice. Unfortunately, health care providers generally report low knowledge of medical cannabis and cite this lack of knowledge as a barrier to making patient recommendations. It is important to understand health care providers' medical cannabis knowledge and its correlates. However, few studies have rigorously assessed clinically relevant cannabis-related knowledge, instead typically focusing on attitudes toward cannabis and perceived knowledge. Methods: Physicians in a university-affiliated health system completed an anonymous online survey. The survey assessed participants' basic demographics and medical experience, experiences with cannabis education, beliefs about their knowledge of and competency regarding medical cannabis, and knowledge of medical cannabis in relation to the current scientific evidence. Results: The average level of medical cannabis knowledge was 58% correct, with scores ranging from 39% to 78% correct. Perceived cannabis knowledge predicted actual knowledge, and those who pursued self-initiated study or attended a lecture on medical cannabis had higher knowledge levels. Conclusion: Levels of factual knowledge about medical cannabis among physicians were moderate. Our results highlight the mismatch between physician knowledge and cannabis policy. We offer our brief, 10-min assessment as a baseline for characterizing cannabis knowledge, acknowledging that the content and interpretation may change as knowledge advances.

Mate value is an important concept in mate choice research although its operationalization and understanding are limited. Here, we reviewed and evaluated previously established conceptual and methodological approaches measuring mate value and presented original research using individual differences in how people view themselves as a face-valid proxy for mate value in long- and short-term contexts. In data from 41 nations (N = 3895, Mage = 24.71, 63% women, 47% single), we tested sex, age, and relationship status effects on self-perceived mate desirability, along with individual differences in the Dark Triad traits, life history strategies, peer-based comparison of desirability, and self-reported mating success. Both sexes indicated more short-term than long-term mate desirability; however, men reported more long-term mate desirability than women, whereas women reported more short-term mate desirability than men. Further, individuals who were in a committed relationship felt more desirable than those who were not. Concerning the cross-sectional stability of mate desirability across the lifespan, in men, short- and long-term desirability rose to the age of 40 and 50, respectively, and decreased afterward. In women, short-term desirability rose to the age of 38 and decreased afterward, whereas long-term desirability remained stable over time. Our results suggest that measuring long- and short-term self-perceived mate desirability reveals predictable correlates.

PURPOSE This study evaluates third-year dental medicine students' perceived competencies related to interprofessional collaborative practice (IPCP) after completing two exposure level experiences with students from other professions across a large academic health center. METHODS Two cohorts of D3 dental medicine students (2018-2019 and 2019-2020) completed the Interprofessional Collaborative Competencies Attainment Survey (ICCAS) after participating in in-person 2.5-h Interprofessional (IP) Forums in the Fall and Spring semesters. Self-reported competencies were compared between pre-and post-IP Forum ratings and between Fall and Spring. RESULTS Prior to the IP Forums, dental medicine students (n = 185) reported perceived skill in the interprofessional competencies to be from Good to Very Good using the ICCAS. After participation in the Fall IP Forum, students' ICCAS scores increased in all ICCAS subscales with large effect sizes. Students reported a perceived decline in these skills in the four months between Fall and Spring IP Forums and restoration of IP skill levels after participating in a second IP Forum (Spring). CONCLUSIONS Participation in IP Forums has a positive impact on students' IPCP skill perception. Our data suggest that perceived skill level requires repeated IP learning experiences. If dental medicine students are expected to embrace collaborative practice to enhance patient outcomes, then dental school educators must provide opportunities for students to engage in collaborative practice experiences at all levels of their training.

The operational sex ratio is a powerful influence on behavior in humans and other species. Although stable on an evolutionary time scale, specific populations may have an imbalanced sex ratio. Following the economic patterns of supply and demand, the rare sex is more valuable in the reproductive market and has lower mating competition and greater selectivity for partners. Because men and women have somewhat divergent reproductive strategies, imbalances in the sex ratio have differential effects. Men leverage their market scarcity for greater sexual access while avoiding long-term relationship commitments. Lower sex ratios, where men are less numerous, are associated with more promiscuous mating strategies, higher rates of infidelity, and low relationship stability. Women can leverage their market scarcity in high sex ratio populations to secure commitment from partners, marry at earlier ages, and obtain greater resource investment; however, women’s ability to pursue infidelity or multiple relationships is typically constrained by cultural practices regulating female sexuality. High sex ratios are associated with greater emphasis on traditional sex roles and norms that both protect and constrain women. Harsh penalties, including death, are possible consequences of women violating cultural norms in such societies. In part due to rates of infidelity, biased sex ratios create important implications for social conditions and public health.

Interest in and availability of psychedelics for therapeutic purposes has increased in recent decades. In a large, anonymous, online survey, we investigated patterns of communication with healthcare providers and awareness and utilization of substance testing kits or services among people using psychedelics naturalistically. The sample population included attendees of a psychedelic activism event and users of psychedelic social media forums. Among 1,435 participants, 72.5% never discussed psychedelic use with their primary care provider (PCP). Only 4.4% reported using psychedelics with a therapist and 3% in clinical settings, although 77.8% were very or extremely likely to take psychedelics with a therapist if one were legally available. While 62.6% of participants were aware of substance testing services, 42.6% of these indicated never using them. Regression analyses identified several variables associated with disclosure to PCP and utilization of substance testing services including age, gender, frequency and number of psychedelics used, and likelihood of consuming psychedelics under the guidance of a therapist if one were legally available. Further research is necessary to investigate these findings among other groups. Our findings suggest that relevant training and education for healthcare providers is needed, along with more visible options for substance identity testing.

Introduction: As more states allow for medical and nonregistered adult cannabis (i.e., marijuana) use, ensuring proper utilization should be a priority. Standardized labeling for foods and pharmaceutical drugs promotes consumer safety. This study investigated cannabis product labeling requirements in the United States. Materials and Methods: Researchers compiled the requirements for cannabis product labeling across 31 U.S. states with medical cannabis programs from state regulatory publications. Results: Information requirements ranged considerably by U.S. state. All states required delta-9-tetrahydrocannabinol content and manufacturer contact information, >80% of states required the batch number, health risks, production tracking, a cannabis symbol, cannabidiol content, children disclaimer, and an impairment disclaimer. There appeared to be a random pattern in requirements for other specific items. The relationships between the extent of cannabis product labeling requirements and the number of years that a state had a medical cannabis program or whether states allowed nonregistered adult use cannabis were not significant, although there was a trend for nonregistered adult use states to require more recommended label attributes. Conclusion: A comprehensive framework for cannabis use is needed to protect the public, maximize benefits, and minimize harms and risks. Standardization of cannabis product labeling requirements would benefit consumers and promote safer and more effective usage of cannabis products.

Background Medical cannabis users report that their knowledge regarding cannabis is predominantly from their own personal experiences and the Internet. Objective We summarize and describe information found through Internet searches on medical cannabis in English language websites. Methods We used terms related to medical cannabis in the Google search engine between November and December 2019. Resulting websites were catalogued and coded for content, including mentions of health and medical conditions, pharmacology, dosage, harmful or adverse effects, harm reduction techniques, cautions or warnings, products for sale, and credentials. Results We coded 344 web pages on 179 unique websites. Cannabis was mentioned for the treatment of 151 different medical and health conditions, only four of the twenty most frequently mentioned conditions have received substantial empirical support for cannabis or cannabinoid treatment. Information content varied widely across sites, only a small proportion of sites included information on pharmacology, dosage, risks, and other aspects that are requirements for pharmaceutical drugs. Information provided was only moderately related to conclusions in the emerging scientific literature. Conclusions Given the rise in cannabis use within the U.S. and the reliance on the Internet as a source of information, considerable efforts are needed to provide accurate on-line cannabis education to minimize harms and maximize benefits for individuals and society.

PurposePeople consider food wasting behavior to be immoral. However, it is not clear whether people who consider food wasting behavior immoral waste less food. Building on previous qualitative studies, we conducted a large-sample quantitative study. We examined whether people who consider food wasting behavior immoral display food wasting behaviors less frequently and whether they waste less food in general. Furthermore, we explored the reasons that make people consider food wasting behavior immoral and whether they affected food wasting.Design/methodology/approachParticipants voluntarily (n = 562) completed a set of questionnaires that measured the frequency of their food wasting behavior, the amount of food wasted in the preceding week, and food wasting moral judgments, including scales, which explored the reasons for judging this behavior as immoral.FindingsWe found that people who regard food wasting behavior as immoral displayed food wasting behavior less frequently, but did not waste less food than people who did not consider food wasting behavior immoral. Furthermore, we found that there are two categories of reasons for moral disapproval of food wasting behavior: externally oriented (concern for the environment, social issues, and for future generations) and internally oriented (concern for ones’ financial situation, social approval, and going by traditional norms). However, only people whose moral judgments were motivated by externally oriented reasons wasted food less frequently.Originality/valueOur findings provide evidence that moral judgments influence food wasting behavior and highlight the importance of the content of moral beliefs for predicting behaviors.

Purpose: To compare cannabis enthusiasts’ knowledge about cannabis risks and effectiveness in treating medical conditions with existing empirical evidence. Design: A brief survey assessed cannabis use, information sources, and knowledge about risks and effectiveness. Setting: A cannabis advocacy event in April 2019 in a state with legal medical and recreational cannabis. Participants: Demographically diverse adults (N = 472) who frequently used cannabis; 85% used cannabis for health or medical purposes. Measures: Participants reported the sources of their cannabis information, health conditions they thought cannabis was effective in treating (n = 10), and health risks increased by cannabis (n = 6). Conditions and risks were based on ratings of evidence (ie, from substantial to insufficient) for therapeutic effects and risks identified in a review by The National Academies of Sciences, Engineering, and Medicine (NASEM, 2017). Analyses: Chi-square tests examined the correspondence between participants’ knowledge and NASEM conclusions. Results: Most participants’ (95% confidence interval [CI]: 74%-81%) knowledge of cannabis was from their own experiences; 18% (95% CI: 14%-21%) received information from primary care providers. On average, participants’ beliefs matched NASEM conclusions for half of effectiveness (95% CI: 50%-53%) and risk items (95% CI: 55%-57%). Many (95% CI: 38%-42%) thought that cannabis use did not increase any risk. Contrary to NASEM conclusions, many thought cannabis was effective in treating cancer (76%), depressive symptoms (72%), and epilepsy (68%). Those who received cannabis information from their primary care providers had better knowledge of medical effectiveness. Medicinal cannabis use frequency inversely predicted knowledge of medical effectiveness and increased risks of adverse events. Conclusion: There were considerable discrepancies between cannabis users’ knowledge and available evidence, highlighting the need for more research and education (by physicians, caregivers, and dispensaries) on effectiveness and health risks, especially for users with specific health issues such as pregnant women and people with depression.

The present study examines the changes in the type and frequency of beverage consumption of Genesee County, Michigan residents before and after the Flint water crisis (FWC). Employing Speak to Your Health! Community Survey data of adults (N=1,825) and random-effects longitudinal ordered logistic regression, we examined between the frequency of daily soda, juice, and other sweetened drinks (OSD) intake in two subpopulations: respondents residing in ZIP codes affected and not affected by lead contamination. After the FWC, African Americans were more likely to consume all three beverage types compared with Whites. It should be noted that the context of the FWC made this a time when mistrust in local government messaging might have been a factor. Within the affected area, African Americans' likelihood of soda, fruit juice, and OSD consumption increased significantly by 156%, 146%, and 924%, respectively.

This article applies a life history model to advance the evolutionary understanding of poetry that inspired nineteenth-century Swedish National Romanticism. We show that the characters featured in two of Erik Gustaf Geijer’s poems, “The Viking” and “The Yeoman Farmer” (1811), display patterns of time perspective, mating effort, and parental invest­ment that are now recognized as central life history attributes: a fast strategy and a slow strategy, respectively. These patterns were identified by undergraduate participants (N = 427) who read excerpts of the poems that had been stripped of identifying information and mentions of romantic or sexual relationships. Participants read each poem and rated each character on validated scales of the life history dimensions of mating effort and paren­tal investment, relationship interests and attractiveness, characteristics of his developmen­tal environment, and physiological characteristics. Results are consistent with generally accepted associations in life history theory and also inform current theoretical develop­ments and debates. Geijer had an intuitive understanding of life history patterns, which he used to create recognizable characters for his Romantic depiction of Swedish history.

Purpose: Food insecurity is a psychosocial stressor with deleterious effects on mental health. This study examined whether the local food environment moderates the association of individual food insecurity with poor mental health. Methods: Cross-sectional survey data were collected from adult residents of Flint, Michigan (n=291), in 2015. Multivariate logistic models assessed whether quality of the local food environment moderated the relationship of food insecurity with poor mental health. A binary indicator of poor mental health was created. Participants were asked to rate their overall “mental or emotional health” using a 5-point Likert scale. Individuals were classified as having either good mental health (i.e., ratings of good, very good, or excellent) or poor mental health (i.e., ratings of fair or poor). Results: In fully adjusted models, food insecurity was associated with 3.2 (95% confidence interval [CI]: 1.6–6.2) times higher odds of poor mental health. However, increased proximate access to vegetables and fruits moderated this association. For example, those in the bottom 25th percentile of access to vegetables had 7.4 (95% CI: 2.7–20.5) times higher odds of poor mental health. In contrast, for those in the top 25th percentile of vegetable access, food insecurity was only marginally associated with poor mental health (odds ratio=2.2; 95% CI: 1.0–4.7). Conclusion: Greater proximate access to vegetables and fruits moderated food insecurity's association with poor mental health. Longitudinal evaluation of programs and policies that improve availability of nutrient-rich foods in food insecure communities is needed to determine whether they yield a mental health benefit.

Evolutionary psychologists propose that men’s conspicuous consumption facilitates mate attraction because it predicts resource investment in offspring. This article elaborates on the ultimate functions of men’s luxury displays based on Life History Theory. Three studies provide evidence for phenotypic mimicry, in which consumer product features mimicking male secondary sex characteristics indicate investment in mating competition, at the expense of paternal investment. Men owning shirts with larger luxury brand logos were rated higher on mating effort, lower on parental investment, higher on interest in brief sexual affairs, lower on interest in long-term committed romantic relationships, higher in attractiveness to women for brief sexual affairs, lower in attractiveness to women for long-term committed relationships, and higher in developmental environment unpredictability compared with men owning shirts displaying a smaller logo. Participants recognized the strategic use of luxury display properties across social contexts but did not consistently associate product properties with owners’ physiological characteristics.

Background People report using cannabis as a substitute for prescription medications but may be doing so without the knowledge of their primary health care providers (PCPs). This lack of integration creates serious concerns, e.g., using cannabis to treat medical conditions that have established treatment options. Methods We conducted an anonymous, cross-sectional online survey among patrons of a medical cannabis dispensary in Michigan (n = 275) to examine aspects of their relationship with their PCP and their perceptions of PCP knowledge related to cannabis. Results Overall, 64% of participants initiated medical cannabis use based on their own experiences vs. 24% citing advice from their PCP. Although 80% reported that their PCP knew they currently used medical cannabis, 41% reported that their PCP had not always known. Only 14% obtained their medical cannabis authorization from their PCP. Only 18% of participants rated their PCP’s knowledge about medical cannabis as very good or excellent and only 21% were very or completely confident in their PCP’s ability to integrate medical cannabis into their treatment. Although 86% had substituted cannabis for pharmaceutical medications, 69% (n = 134) of those who substituted reported some gap in their PCP’s knowledge of their substitution, and 44% (n = 86) reported that their PCP was currently unaware of their substitution. Conclusions Patients frequently substitute cannabis for prescription drugs, often without PCP knowledge. Although most participants disclosed cannabis use to their PCP, their perceptions of PCP knowledge ranged widely and many obtained medical cannabis licensure from an outside physician. Our results highlight the need for standardized physician education around appropriate medical cannabis use.

Although the associations between the consumption of alcohol, unhealthy foods, and obesity are known, there is no consensus on the mechanisms involved. Previous research demonstrates that the type of foods available during the peak times for alcohol consumption differ from those available at other times. Advertisements targeting college students indicate an awareness of increased cravings for “junk foods” following alcohol consumption, however there is no previous research on how alcohol consumption affects actual dietary choices differentially by type of food, in comparison to non-alcohol related food consumption. The current study demonstrates that college students’ food cravings increase, consumption of fruits and vegetables is lower, and consumption of junk foods is higher with alcohol consumption than at other times. Respondents reported eating something that they were craving the majority (57%) of the time; however, on average they ate something healthier than what they were craving 27% of the time. These findings help to clarify the behavioral mechanisms underlying the relationship between alcohol consumption, unhealthy dietary behaviors, and obesity.

Highlights • We assessed effects of COVID-19 related changes on people using cannabis. • 48.8% of participants were concerned about COVID-19 affecting cannabis access. • 32.3% of participants reported starting use of a medication or licit drug due to COVID-19. • 47.5% of participants reported increased use of a medication or licit drug due to COVID-19. • Nearly half of increased use was subjectively attributed to changes in ability to access cannabis., Background The ongoing COVID-19 pandemic strains the medical system, limiting access to healthcare services. Many people use cannabis medically for chronic health conditions and as a substitute for other medications. As such, changes in cannabis access associated with COVID-19 may result in increased non-cannabis drug use. Methods We recruited N = 353 individuals through Amazon Mechanical Turk who reported current medical cannabis use in April and May of 2020. We assessed the effects of the COVID-19 pandemic on patterns of medication and substance use, as well as on cannabis use patterns. Results Over half of participants either started using or increased use of medications or substances because of the COVID-19 pandemic, most commonly alcohol and sleep aids. Over a third of participants increased cannabis use while 25% decreased cannabis use. Approximately 40% of participants who increased or started use of medications/substances (other than cannabis) reported doing so because of changed access to medical cannabis. Conclusion The reported increase in drug use among people using medical cannabis is concerning. Because the pandemic will likely continue for months (or even years), having a better understanding of why this is occurring is critical for developing effective harm-reduction strategies in this population.
