Purpose: Intimate partner violence (IPV) is prevalent in the U.S., and has many physical and mental health implications. While several studies have explored the impact of IPV experience on individuals, less is known about which factors are predictive of IPV victimization. Method: The current study examined the extent to which substance use, self-efficacy, and differentiation each predicted experiences of IPV among women seeking treatment for a substance use disorder using a multinomial logistic regression analysis. Results: Results showed that women who reported lower levels of differentiation were significantly more likely to experience IPV. However, no other significant IPV predictors were found. Conclusions: Current findings suggest that differentiation may be an effective therapeutic target for IPV prevention. [ABSTRACT FROM AUTHOR]

Background: Prescription drug, e-cigarette, smokeless tobacco, and synthetic marijuana use has risen dramatically in the United States over the past decade.Objectives: This paper investigates the use of risky substances among adolescents, and examines disparities between sexual minority (i.e., mostly heterosexual and lesbian, gay, bisexual; LGB) and heterosexual adolescents in use of novel and emerging substances. Given the public health risk and the imminence of these substances in the media, emerging drug use was examined in a county wide sample of adolescents in a Southern state.Methods: A probability sample of middle and high school students (N= 3012; ages 11–18) using random cluster methods was obtained in a mid-sized school district in the Southeastern United States.Results: LGB adolescents reported higher past-30 day and lifetime use of cigarettes (AORs =2.77, 2.90, respectively), smokeless tobacco (lifetime only: AOR = 1.88), e-cigarettes (lifetime only; AOR = 1.92), alcohol (AORs = 1.7, 2.20), marijuana (AORs = 3.02, 3.06), synesthetic marijuana (AORs = 3.77, 2.48), and prescription drugs (AORs = 3.82, 2.55). Adolescents who self-identified as “mostly heterosexual” reported higher lifetime cigarette use, and past 30-day use of e-cigarettes and prescription drugs as compared with heterosexual adolescents.Conclusions: Our results are notable given the dearth of data documenting use of increasingly emerging or “trendy” substances such as prescription drugs. More research is needed to understand the underlying cause of these disparities, and efforts should be targeted toward this population to reduce negative outcomes from misuse.

Objective: Social support and life chaos have been inversely associated with increased risk of HIV infection. The purpose of this study was to explore among a sample of HIV-negative methamphetamine-using men who have sex with men (MSM) the association between engaging in transactional sex, life chaos, and low social support. Methods: HIV-negative methamphetamine-using MSM completed an online questionnaire between July and October 2012 about recent substance use and sexual behavior. Bivariate and multivariate tests were used to obtain statistically significant associations between demographic characteristics, engaging in transactional sex, life chaos, and the participants' perception of their social support. Results: Of the 325 participants, 23.7% reported engaging in transactional sex, 45.2% reported high life chaos, and 53.5% reported low perceived social support. Participants who engaged in transactional sex were more likely to have high life chaos than participants who did not (aOR = 1.70, 95% CI = [1.01, 2.84]); transactional sex was not associated with social support. Participants with high life chaos were more out about their sexual orientation (aOR = 2.29, 95% CI = [1.18, 4.42]) and more likely to perceive they had low social support (aOR = 3.78, 95% CI = [2.31, 6.22]) than participants with low life chaos. Non-Latinos perceived they had less social support than Latinos (aOR = 0.48, 95% CI = [0.25, 0.92]). Conclusions: Methamphetamine-using MSM engaging in transactional sex experience more life chaos than those who do not engage in transactional sex. Outness, perceived social support, and ethnicity are associated with life chaos. [ABSTRACT FROM AUTHOR]

Background: Heavy episodic drinking (HED) has negative consequences for both the individual and society. Research on HED has focused mainly on the general population while research into HED and other drug use among recreational drug using populations is less developed. Objectives: This study explores factors related to HED on a previous weekend among male and female recreational drug users. Methods: Cross-sectional interviews were undertaken with those age 19+ who regularly use recreational drugs in a nightlife setting in two cities in Canada (n = 931) between 2008 and 2014. Participants were asked about their alcohol and other drug use the previous Friday or Saturday. Chi-square bivariate tests were used to determine factors significantly associated with HED with significant variables then entered into multivariate logistic regression models to determine related factors for men and women. Results: Results showed that 53.4% of all participants met criteria for HED the previous weekend and the majority of those had used at least one other drug. Multivariate models showed being in postsecondary full-time, being between 19 and 25, using cocaine and using tobacco the previous weekend was associated with HED for men. For women, using cocaine the previous weekend was associated with HED, while being 26 and over, married or common law and using marijuana was associated with lower odds of HED. Conclusion: HED is common among recreational drug users but different factors were associated HED for men and women. Interventions for recreational drug users should include both alcohol and other drug messaging and be gender specific. [ABSTRACT FROM AUTHOR]

Background: Young Black men who have sex with men (YBMSM) are at highest risk for HIV seroconversion in the United States. Successful movement through the HIV care continuum is an important intervention for limiting onwards HIV transmission. Objective: Little data exists on how substances most commonly used by YBMSM, such as marijuana, are related to the HIV continuum, which represents the primary aim of this study. Methods: A cohort of YBMSM (n = 618) was generated through respondent-driven sampling. Frequency of marijuana use and marijuana use as a sex-drug were assessed across the HIV care continuum using weighted logistic regression models. Results: Study participants reported more intermittent marijuana use (n = 254, 56.2%) compared to heavy use (n = 198, 43.8%). Our sample contained 212 (34.3%) HIV seropositive participants of which 52 (24.5%) were unaware of their HIV positive status. Study participants who were heavy marijuana users were more likely to be unaware of their HIV seropositive status (AOR: 4.18; 95% CI 1.26, 13.89). All other stages in the care continuum demonstrated no significant differences between those who use marijuana intermittently or heavily or as a sex-drug and nonusers. Conclusions: YBMSM who used marijuana heavily were more likely to be HIV-positive unaware than those who never used marijuana. Findings were inconclusive regarding the relationships between marijuana use and other HIV care continuum metrics. However, knowledge of ones' HIV status is a critical requirement for engaging in care and may have implications for onwards HIV transmission. [ABSTRACT FROM AUTHOR]

Background: Substance use has been identified as one of the leading factors related to HIV transmission in the United States. The association of problematic drinking with sexual risk behavior puts individuals at greater risk for HIV transmission. This may be of particular concern for women given that approximately 66% of new HIV infections occurring through heterosexual transmission are female. Objectives: To investigate alcohol use severity and sexual risk behavior among females who use heavy, illicit drugs. Methods: Female substances users (N = 251; Mage = 31.90, SD = 7.67; 63.7% Black) self-reported past month alcohol use and lifetime sexual risk behaviors with both casual and steady sex partners. Results: Problematic alcohol users were more likely to use noninjection drugs and less likely to use injection drugs than abstainers and more likely than moderate alcohol users to use alcohol before/during sex with a steady partner. White problematic alcohol users were less likely to use injection drugs before/during sex with a steady partner than abstainers. Black problematic alcohol users were more likely to use non-injection and alcohol than moderate alcohol users before/during sex with steady partners. Conclusions: The current study extends the existing literature by taking a closer look at the role of alcohol use severity in sexual risk taking behavior of Black and White female substance users, a particularly vulnerable group for HIV transmission.

Background: There is increasing evidence that Synthetic Cannabinoid (SC) use is associated with adverse health effects, but little is known about the prevalence of SC use and risk and protective factors for SC use among adolescents.Objectives: To determine the prevalence and correlates of any and frequent SC use in a representative sample of high school students.Methods: The 2013 Youth Risk Behavior Survey was administered to 3,928 high school students in Nevada. A state-added question assessed any and frequent SC use (10 or more times). Weighted logistic regression identified factors for both outcomes.Results: 17.3% of students reported SC use and 4.3% used SCs frequently. As expected, there were strong associations between SC use and other substance use. After controlling for substance use, any SC use was associated with being Hispanic (AOR = 1.74; 95% CI = 1.27, 2.38) and living in a rural county (AOR = 1.68; 95% CI = 1.26, 2.23). Frequent SC use was higher among students who were male (AOR = 2.14; 95% CI = 1.19, 3.84), 18 years of age (AOR = 2.34; 95% CI = 1.18, 4.67), lived in a rural county (AOR = 1.84; 95% CI = 1.11, 3.04), and were offered, sold, or given illegal drugs on school property (AOR = 2.40; 95% CI = 1.53, 3.79). Protective factors for frequent SC use included high parental monitoring (AOR = 0.54; 95% CI = 0.31, 0.93) and sports team participation (AOR = 0.61; 95% CI = 0.37, 0.99).Conclusions/Importance: SC prevention policies and programs should focus on adolescents who live in rural settings and engage in substance use. Initiatives to address drug availability as school and promote parent involvement are also warranted. [ABSTRACT FROM PUBLISHER]

Background: Studies on associations between body weight status and specific substance use have provided conflicting findings. Objectives: This paper investigated the association between substance use and body weight status among African American women. Methods: We analyzed the data from 328 African American women who were enrolled in a HIV prevention intervention in Baltimore, MD, USA, in order to investigate the association between substance use and their body weight status. Participants' anthropometry was measured by trained research staff. Substance use information was collected via self-administered and interviewer-administered questionnaires. Results: About 33.4% were classified as normal/underweight, 24.2% overweight, and 42.4% obese. Compared to overweight (38.5%) and obese (29.2%) participants, the normal/underweight women had significantly higher prevalence of drug use (52.8%) (χ2= 14.11, p < 0.05). BMI was significantly negatively associated with current heroin use (t = −2.21, p < 0.05). The risk of being overweight and obesity was lower among active marijuana (z = −2.05, p < 0.05) and heroin users (z = −1.91, p < 0.10) than among non-marijuana/non-heroin users. Heroin smokers had lower body weight (t = −3.02, p < 0.05) and BMI (t = −2.47, p < 0.05) than non-heroin smokers. The decrease in BMI appeared to be greater among more frequent (≥once/day) heroin users (t = −2.39, p <0.05) as compared to the less frequent heroin users (

Background: Health risks associated with abstention from alcohol drinking in previous studies may have been exaggerated because the pool of abstainers in many studies included both lifetime abstainers and ex-drinkers, including sick-quitters. Objectives: This study compared sociodemographic and health statuses among lifetime abstainers, exdrinkers, bingers, and nonbingers in the 50–64 age group (baby boomers) and the 65+ age group. Methods: Data are from the 2008 to 2012 National Survey on Drug Use and Health (N = 18,443 for the 50–64 age group and N = 11,191 for the 65+ age group). Descriptive statistics and multinomial and binary logistic regression analyses were used to examine the study questions. Results: 10% of the 50–64 age group and 20% of the 65+ age group reported lifetime abstention, and 21% and 28% of each group, respectively, reported being ex-drinkers (i.e., last used alcohol more than 12 months ago). In both age groups, lifetime abstainers, exdrinkers, and bingers had lower socioeconomic status than nonbingers. In the 50–64 age group, lifetime abstainers did not differ from or were less likely than nonbingers to have vascular and hepatic/gastrointestinal (HGI) disorders, but exdrinkers were more likely to have these diseases, and both lifetime abstainers and exdrinkers were more likely to have diabetes. In the 65+ age group, lifetime abstainers did not differ from nonbingers on high blood pressure, heart disease, and HGI, but both they and the exdrinkers were more likely to have stroke and diabetes. Conclusions/Importance: Diabetes screening/monitoring and stroke prevention/care are recommended for both age groups of abstainers and exdrinkers. [ABSTRACT FROM AUTHOR]

Background: On October 2012, Hurricane Sandy struck New York City, resulting in unprecedented damages, including the temporary closure of Bellevue Hospital Center and its primary care office-based buprenorphine program. Objectives: At 6 months, we assessed factors associated with higher rates of substance use in buprenorphine program participants that completed a baseline survey one month post-Sandy (i.e. shorter length of time in treatment, exposure to storm losses, a pre-storm history of positive opiate urine drug screens, and post-disaster psychiatric symptoms). Methodology: Risk factors of interest extracted from the electronic medical records included pre-disaster diagnosis of Axis I and/or II disorders and length of treatment up to the disaster. Factors collected from the baseline survey conducted approximately one month post-Sandy included self-reported buprenorphine supply disruption, health insurance status, disaster exposure, and post-Sandy screenings for PTSD and depression. Outcome variables reviewed 6 months post-Sandy included missed appointments, urine drug results for opioids, cocaine, and benzodiazepines. Results: 129 (98%) patients remained in treatment at 6 months, and had no sustained increases in opioid-, cocaine-, and benzodiazepine-positive urine drug tests in any sub-groups with elevated substance use in the baseline survey. Contrary to our initial hypothesis, diagnosis of Axis I and/or II disorders pre-Sandy were associated with significantly less opioid-positive urine drug findings in the 6 months following Sandy compared to the rest of the clinic population. Conclusion: These findings demonstrate the adaptability of a safety net buprenorphine program to ensure positive treatment outcomes despite disaster-related factors. [ABSTRACT FROM AUTHOR]

Background: Recent studies have reported high rates ofTrichomonas vaginalisamong middle age and older adults. Though trichomoniasis risk factors in this age cohort remain largely unknown, illicit drug use has been associated with increased incidence of sexually transmitted infections (STIs). The number of mid-older adults using illicit drugs has increased significantly in recent years suggesting the need to understand the relationship between drug use and STIs in this age cohort.Objectives: This study examined the relationship between drug use, sexual-risk behaviors, and biologically confirmedT. vaginalisin a sample of mid-older and younger adults who reported recent drug use.Methods: The cross-sectional design examined the relationship between past 6-month drug use, sexual risk-behaviors, and PCR-confirmedT. vaginalisin 264 adults age 18–64 who were recruited from Baltimore, Maryland. These relationships were also explored in the age-stratified sample among those 18–44 years (“younger”) and individuals 45+ years (“mid-older”).Results: Trichomoniasis prevalence did not differ significantly between younger (18.8%) and mid-older (19.1%) adults. Mid-older adults that tested positive forT. vaginaliswere more likely to have used marijuana and crack in the past 6 months. Among younger adults, there were no associations between trichomoniasis and past 6-month drug use and sexual-risk behavior.Conclusions/Importance: Age- and drug-related immune decline is hypothesized to contribute to increase susceptibility toT. vaginalisin mid-older adults. Broad screening for trichomoniasis, particularly among older adults who are often not regarded as at risk for STIs, is needed to control this often asymptomatic infection. [ABSTRACT FROM PUBLISHER]

Background: Although most people who inject drugs (PWID) in Tijuana, Mexico, primarily inject heroin, injection and non-injection use of methamphetamine and cocaine is common. We examined patterns of polydrug use among heroin injectors to inform prevention and treatment of drug use and its health and social consequences. Methods: Participants were PWID residing in Tijuana, aged ≥18 years who reported heroin injection in the past six months and were recruited through respondent-driven sampling (n = 1,025). Latent class analysis was conducted to assign individuals to classes on a probabilistic basis, using four indicators of past six-month polydrug and polyroute use: cocaine injecting, cocaine smoking or snorting, methamphetamine injecting, and methamphetamine smoking or snorting. Latent class membership was regressed onto covariates in a multinomial logistic regression. Results: Latent class analyses testing 1, 2, 3, and 4 classes were fit, with the 3-class solution fitting best. Class 1 was defined by predominantly heroin use (50.2%, n = 515); class 2 by methamphetamine and heroin use (43.7%, n = 448), and class 3 by methamphetamine, cocaine, and heroin use (6.0%, n = 62). Bivariate and multivariate analyses indicated a group of methamphetamine and cocaine users that exhibited higher-risk sexual practices and lower heroin injecting frequency, and a group of methamphetamine users who were younger and more likely to be female. Conclusions: Discrete subtypes of heroin PWID were identified based on methamphetamine and cocaine use patterns. These findings have identified subtypes of heroin injectors who require more tailored interventions to reduce the health and social harms of injecting drug use. [ABSTRACT FROM AUTHOR]

Background: The use of brief, reliable, valid, and practical measures of substance use is critical for conducting individual (risk and need) assessments in probation practice. In this exploratory study, the basic psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT) are evaluated. Methods: The instruments were administered as an oral interview instead of a self-report questionnaire. The sample comprised 383 offenders (339 men, 44 women). A subset of 56 offenders (49 men, 7 women) participated in the interrater reliability study. Data collection took place between September 2011 and November 2012. Results: Overall, both instruments have acceptable levels of interrater reliability for total scores and acceptable to good interrater reliabilities for most of the individual items. Confirmatory factor analyses (CFA) indicated that the a priori one-, two- and three-factor solutions for the AUDIT did not fit the observed data very well. Principal axis factoring (PAF) supported a two-factor solution for the AUDIT that included a level of alcohol consumption/consequences factor (Factor 1) and a dependence factor (Factor 2), with both factors explaining substantial variance in AUDIT scores. For the DUDIT, CFA and PAF suggest that a one-factor solution is the preferred model (accounting for 62.61% of total variance). Conclusions: The Dutch language versions of the AUDIT and the DUDIT are reliable screening instruments for use with probationers and both instruments can be reliably administered by probation officers in probation practice. However, future research on concurrent and predictive validity is warranted. [ABSTRACT FROM AUTHOR]

Background and Objectives: This study sought empirical evidence for the self-medication hypothesis. It asked whether diagnosis of depression, together with the use of mental-health care, leads to substance use.Methods: Data came from the 5-wave, longitudinal Fragile Families and Child Wellbeing (FFCW) Study, an investigation of a cohort of nearly 5,000 births, which oversampled non-marital births. FFCW examined newborns’ biological mothers and fathers, all of whom lived in the United States. The adults were initially interviewed between 1998 and 2000 (the period of the cohort's births); they were then re-interviewed for four times over 10 years. FFCW measured mental health-related variables, level of drug use, and social structural and demographic factors, all of which are also measured by the present study. Respondents in our study's two final subsamples had responded to every FFCW interview item we would use in constructing our final model's variables. Our subsample of mothers totaled 3,477 women, from whom 5,987 person-waves were derived. Our subsample of fathers totaled 2,096 men, yielding 3,543 person-waves.Results: We used STATA generalized estimating equations for panel data, and found some evidence to support the self-medication hypothesis. In addition, our results indicated that the relationship of substance use to the use of mental-health care was gender-specific.Conclusions/Importance: Empirical evidence from this study only partially supported the self-medication hypothesis; the co-occurrence of depression and substance abuse in our sample was also reflective of social structural and demographic variables and of prior substance use variables.

Background: Little research has focused specifically on alcohol, tobacco, and other drug (ATOD) use of lesbian and bisexual women in general or the college subgroup specifically. Previous research shows sexual minority women at increased risk when compared to their heterosexual counterparts. Objectives: The purpose of the current study was to compare ATOD use of lesbian, bisexual, and heterosexual undergraduate college women. Methods: A secondary analysis of three fall semesters (2009-2011) of American College Health Association-National College Health Assessment (ACHA-NCHA-II) data was conducted. Women who self-identified as gay/lesbian ( N = 538), bisexual ( N = 1579), and heterosexual ( N = 40,869) were compared on ATOD use. Chi-square Tests were used to analyze differences between the groups and logistic regression determined odds ratios of ATOD use. Results: Bisexual women had greater odds of using alcohol, tobacco, and marijuana than heterosexual women and lesbians. They also had greater odds of using all illicit drugs (except steroids) and misusing prescription drugs than heterosexual women and greater odds of using amphetamines other than meth, sedatives, and ecstasy when compared to lesbians. Lesbians had greater odds of using tobacco, marijuana, sedatives, hallucinogens, other illegal drugs and misusing prescription drugs than heterosexual women. Conclusions/Importance: The study confirms increased ATOD use among sexual minority women as compared to their heterosexual counterparts with bisexual women having the highest use. This is the first study to examine misuse of prescription drugs among a large number of lesbian and bisexual college women, and contributes to the scant literature addressing college women's ATOD use by sexual orientation.

Background: While researchers have identified factors that contribute to youth violence, less is known about the details of violent incidents. In addition, substance use has been linked to youth violence; however, little is known about actual substance use on days in which violence occurs. Objective: This study examined reasons for peer violence and the association between substance use and violence using daily calendar-based analyses among at-risk urban youth. Methods: Data were collected from Emergency Department (ED) patients (ages 14-24; n = 599; 59% male, 65% African American) who screened positive for substance use in the past 6 months. Daily data regarding past 30-day substance use and violence and reasons for violent incidents were obtained via semi-structured interviews. Multi-level multinomial regression models were conducted to test the associations between substance use and peer violence incidents (i.e., none, moderate and severe). Results: Conflict over 'personal belongings' was a common reason for violence among males; 'jealousy'/'rumors' were common reasons among females. Moderate victimization was more likely to be reported on days in which participants reported alcohol and cocaine use. Severe victimization was more likely to be reported on days in which participants reported alcohol use. Moderate or severe aggression was more likely to be reported on days in which participants reported alcohol and non-medical sedative use. Conclusions: Results suggest that youth violence prevention that addresses differential reasons for violence among males and females as well as substance use would be beneficial.

This study investigated the role of psychological variables and judicial problems in treatment retention for a low-threshold methadone program in Montreal, Canada. Logistic regression analyses were computed to examine associations between psychological variables (psychological distress, self-esteem, stages of change), criminal justice involvement, and treatment retention for 106 highly-disorganized opioid users. Higher methadone dosage was associated with increased odds of treatment retention, whereas criminal charges and lower self-esteem decreased these odds. Psychological variables could be identified early in treatment and targeted to increase potential treatment retention. Financial support for this study was provided by the Fonds de Recherche en Santé du Québec. [ABSTRACT FROM AUTHOR]

Background: Although ecstasy (MDMA) use is not as prevalent in the United States (US) as it was in the early 2000s, use remains popular among adolescents and young adults. Few recent studies have examined ecstasy use in national samples among those at particularly high risk for use-adolescents approaching adulthood. Research is needed to delineate sociodemographic correlates of use in this group. Methods: Data were examined from a nationally representative sample of high school seniors in the US (modal age = 18) from the Monitoring the Future study (years 2007-2012; weighted N = 26,504). Data from all cohorts were aggregated and correlates of recent (last 12-month) use of ecstasy were examined. Results: Roughly 4.4% of high school seniors reported use of ecstasy within the last year. Females and religious students were consistently at lower odds for use. Black and Hispanic students, and students residing with two parents, were at lower odds for ecstasy use, until controlling for other drug use. Odds of use were consistently increased for those residing in a city, students with weekly income of >$50 from a job, and students earning >$10 weekly from other sources. Lifetime use of alcohol, cigarettes, marijuana, and other illicit drugs each robustly increased odds of ecstasy use. Conclusion: Subgroups of high school seniors, defined by specific sociodemographic factors, and those who have used other drugs, are currently at high risk for ecstasy initiation and use. Since ecstasy is regaining popularity in the US, prevention efforts should consider these factors. [ABSTRACT FROM AUTHOR]

To investigate the involvement of COMT Val158Met and DAT1 3′-UTR VNTR genotypes in the pathogenesis of illicit drug use and drug-induced psychotic disorders (DIP), 187 substance users and 386 normal controls were recruited from Northern Taiwan. Substance users and normal controls significantly differed in allele frequencies of COMT Val158Met ( p = 0.039) but not in allele frequencies of DAT1 3′-UTR VNTR ( p = 0.879). However, neither allele frequencies of COMT Val158Met nor allele frequencies of DAT1 3′-UTR VNTR were associated with DIP. The findings should be confirmed in further studies of a larger sample size and a more homogenous patient group. [ABSTRACT FROM AUTHOR]

Methamphetamine use has increased substantially in the United States since the 1990s. Few studies have examined the healthcare service needs of women who use methamphetamine. This study describes unmet medical needs in a community-based sample of women who use methamphetamine in San Francisco, CA. Women who use methamphetamine were recruited in San Francisco and participated in a computer-assisted survey ( N = 298 HIV-negative women). Multivariate analysis was performed to explore associations among sociodemographic variables, drug use, use of health and social services, and unmet healthcare need across three domains: chronic health problems, dermatologic problems, and women's preventive healthcare. Sixty-nine percent of participants reported a need for care for a chronic health condition, and 31% of them had an unmet need for care, in the last six months. Thirty-five percent of participants reported a need for dermatologic healthcare, and 66% had an unmet need for care in the last 6 months. Ninety-two percent of participants reported a need for women's preventive healthcare and 46% had an unmet need for care in the last year. Women who reported having a healthcare provider had lower odds of reporting an unmet need for a chronic health condition or women's preventive healthcare. Women who used a case manager had lower odds of having an unmet need for dermatologic care. A significant proportion of women who use methamphetamine in this sample had an unmet need for women's preventive healthcare, and overall these women had a significant unmet need for healthcare. These findings suggest that contact with a healthcare provider or a caseworker could help to expand access to healthcare for this vulnerable population. [ABSTRACT FROM AUTHOR]

This study examined mortality and predictors of death in 1,396 primary amphetamine users (85% males) who were interviewed with the Addiction Severity Index in the Swedish criminal justice system during 2000-2006 and followed through 2008. Forty-nine clients deceased (standardized mortality ratio 4.1 [3.0-5.4]), at least 84% of deaths were violent or drug-related (12% suicides), and Cox regression analysis indicated that death was associated with frequent use of sedatives and less frequent use of amphetamine. No female deaths were observed; death and male gender were associated in binary analysis. Implications for diagnostics and treatment are discussed. [ABSTRACT FROM AUTHOR]

We examine psychological distress (PD) in young adult Ecstasy users in relation to age of initiation and frequency of use of Ecstasy, cannabis, alcohol, and tobacco. Using two Australian community samples, we assess whether different sampling methods produce comparable estimates of these associations. The Natural History Study of Drug Use (NHSDU; N = 339) in 2009 used population sampling and the 2009 Ecstasy and Related Drug Reporting System (EDRS; N = 359) used purposive sampling. Participants, aged 19-23 years, were recurrent Ecstasy users. PD was assessed using Kessler 10 in the EDRS and Hospital Anxiety Depression Scale in the NHSDU. In both samples, PD was associated with daily tobacco use and early drug initiation, but not frequent Ecstasy use. One-third smoke tobacco daily. Study limitations and implications are noted.

This study examines the role of spirituality as a moderator of the relationship between traumatic life experiences, mental health, and drug use in a sample of African American women. It was hypothesized that there would be an inverse relationship overall between spirituality and mental health and drug use among this sample of African American women. Secondly, was expected that spirituality would moderate the relationship between traumatic life events and mental health and drug use. African American women ( n = 206) were recruited from the community and from probation officers in three urban areas of a southern state, and face-to-face interviews were completed. Findings indicated that there was a main effect for spirituality (as measured by existential well-being on the Spiritual Well-Being Scale) and traumatic life events, mental health, and alcohol use. In addition, spirituality was a significant moderator of the relationship between traumatic life events and cocaine use. Discussion and implications for African American women are included.

Cohort study on 471 subjects resident in the metropolitan area of Bologna who had visited a public treatment center for problems due to the abuse of cocaine from January 1, 1988 to December 31, 2009. Two user typologies were created: cocaine users (no heroin) and heroin and cocaine users. Crude mortality rates and standardized mortality ratios were calculated. We performed a regression analysis using the Poisson method. The study results show a higher mortality risk for those injecting substances and for subjects who took both heroin and cocaine. They appear to have different characteristics from their counterparts who do not use heroin. Future studies should be oriented to this aspect. [ABSTRACT FROM AUTHOR]

This online panel study ( nt1 = 5,882; nt2 = 3,486 (randomly selected)) used multiple metrics to assess the prevalence of the nonmedical use of prescription medication for enhancing cognitive performance among German university students in 2010. Rare events logistic regression revealed that increased cognitive test anxiety increased the prevalence of medication use over various time windows. Negative binomial regression models showed that the higher the cognitive test anxiety, the higher the use frequencies were during the previous six months. The models controlled for expected side effects, risk attitudes, self-attributed competencies, prior medication use, sex, and age. We also discuss the study's implications. [ABSTRACT FROM AUTHOR]

The study describes the knowledge of and attitudes toward substance use among street-involved youth in Kenya, and how they relate to their substance use practices. In 2011, 146 children and youth ages 10-19 years, classified as either children on the street or children of the street were recruited to participate in a cross-sectional survey in Eldoret, Kenya. Bivariate analysis using χ2 or Fisher's Exact Test was used to test the associations between variables, and multiple logistic regression analysis was used to identify independent covariates associated with lifetime and current drug use. The study's limitations and source of funding are noted. [ABSTRACT FROM AUTHOR]
