[PMID: 33483851 PMCID: PMC8295412 DOI: 10.1007/s10508-020-01850-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Revised: 09/14/2020] [Accepted: 09/23/2020] [Indexed: 05/10/2023]
Abstract
Syndemic theory posits that "syndemic conditions" (e.g., alcohol misuse, polydrug use, suicidality) co-occur among sexual minority men and influence HIV-risk behavior, namely HIV acquisition and transmission risk. To examine how four syndemic conditions cluster among sexual minority men and contribute to HIV-risk behavior, we conducted latent class analysis (LCA) to: (1) classify sexual minority men (n = 937) into subgroups based on their probability of experiencing each syndemic condition; (2) examine the demographic (e.g., race/ethnicity) and social status (e.g., level of socioeconomic distress) characteristics of the most optimally fitting four syndemic classes; (3) examine between-group differences in HIV-risk behavior across classes; and (4) use syndemic class membership to predict HIV-risk behavior with sexual minority men reporting no syndemic conditions as the reference group. The four classes were: (1) no syndemic, (2) alcohol misuse and polydrug use syndemic, (3) polydrug use and HIV syndemic, and (4) alcohol misuse. HIV-risk behavior differed across these latent classes. Demographic and social status characteristics predicted class membership, suggesting that syndemic conditions disproportionately co-occur in vulnerable subpopulations of sexual minority men, such as those experiencing high socioeconomic distress. When predicting HIV-risk behavior, men in the polydrug use and HIV syndemic class were more likely (Adjusted Risk Ratio [ARR] = 2.93, 95% CI: 1.05, 8.21) and men in the alcohol misuse class were less likely (ARR = 0.17, 95% CI: 0.07, 0.44) to report HIV-risk behavior than were men in the no syndemic class. LCA represents a promising methodology to inform the development and delivery of tailored interventions targeting distinct combinations of syndemic conditions to reduce sexual minority men's HIV-risk behavior.

Ventral striatum regulates behavioral response to ethanol and MDMA combination. Addict Biol 2021; 26:e12938.

Abstract
Our previous studies consistently showed that MDMA-induced locomotor hyperactivity is dramatically increased by coadministration of ethanol (EtOH) in rats, indicating possible potentiation of MDMA abuse liability. Thus, we aimed to identify the brain region(s) and neuropharmacological substrates involved in the pharmacodynamics of this potentiation. We first showed that potentiation of locomotor activity by the combination of ip administration of EtOH (1.5 g/kg) and MDMA (6.6 mg/kg) is delay sensitive and maximal when both drugs are injected simultaneously. Then, we used the 2-deoxyglucose quantitative autoradiography technique to assess the impact of EtOH, MDMA, or their combination on local cerebral metabolic rates for glucose (CMRglcs). We showed a specific metabolic activation in the ventral striatum (VS) under MDMA + EtOH versus MDMA or EtOH alone. We next tested if reversible (tetrodotoxin, TTX) or permanent (6-hydrodoxyopamine, 6-OHDA) lesion of the VS could affect locomotor response to MDMA and MDMA + EtOH. Finally, we blocked dopamine D1 or glutamate NMDA receptors in the VS and measured the effects of MDMA and MDMA + EtOH on locomotor activity. We showed that bilateral reversible inactivation (TTX) or permanent lesion (6-OHDA) of the VS prevented the potentiation by EtOH of MDMA-induced locomotor hyperactivity. Likewise, blockade of D1 or NMDA receptors in the VS also reduced the potentiation of MDMA locomotor activity by EtOH. These data indicate that dopamine D1 and glutamate NMDA receptor-driven mechanisms in the VS play a key role in the pharmacodynamics of EtOH-induced potentiation of the locomotor effects of MDMA.

Abstract
The use of multiple psychoactive substances is a widespread phenomenon among people who use drugs. Yet the concept of polydrug use is poorly defined in the social sciences. As a result, theoretical and empirical knowledge of polydrug use is underdeveloped; approaches to measuring polydrug use are inconsistent; and understandings of the cultural meanings of combining substances are limited. This article draws on a collaborative synthesis of three qualitative case studies of polydrug use from four countries: Australia and France, Finland, and Ireland. All three studies explored the practice of substance combination, or “combos” using the lens of intentionality, functionality, and social setting. In addition, the studies shared a common concern with teasing out the rationale for substance combining, and the controls used to balance pleasures with risks, beyond the simple physiological or sensory effects of substances. Our analysis leads us to recommend that a standard definition of polydrug use be adopted for future social science research—that is, the ingestion of two or more substances in combination, at the same time or in temporal proximity, so that the effects of different substances overlap. For analytical purposes, we suggest two subcategories: simultaneous and sequential intake. Moreover, we contend that it is the intention, meaning, and socio-structural context underpinning the use of substance combinations that is central to understanding polydrug use. Consequently, we suggest an adaptation of Zinberg’s seminal concept to one of “drug combo, set, and setting” to incorporate an analysis of the effects of using substances together, or in sequence within a short time frame.

Abstract
Background
Novel psychoactive substances (NPSs) contribute to the public health impact of substance misuse. This report provides research evidence addressing 11 research questions related to NPSs, covering types, patterns and settings of use; supply sources; and implications for policy and practice.
Methods
The study used a conceptually linked three-phase mixed-methods design with a shared conceptual framework based on multiple-context risk and protective factors. Phase 1 was a quantitative phase involving secondary data analysis of the longitudinal Belfast Youth Development Study (BYDS), a latent class analysis using the 2039 BYDS participants. Phase 2 was an extensive qualitative analysis via narrative interviews with participants, sampled from BYDS, drug/alcohol services and prisons, to explore NPS use trajectories. Phase 3 was the final quantitative phase; generalisability of the shared risk factor part of the model was tested using the manual three-step approach to examine risk factors associated with latent class membership. The quantitative and qualitative analyses were integrated, thus allowing emerging findings to be further explored.
Results
The data suggest that NPSs have a place within a range of polydrug use trajectories. Models showed no distinctive NPS class, with no clear evidence of differential risks for NPS use compared with the use of other substances. From the qualitative analysis, a taxonomy of groups was derived that explored how and where NPSs featured in a range of trajectories. This taxonomy was used to structure the analysis of factors linked to use within a risk and protective framework. Drivers for use were considered alongside knowledge, perceptions and experience of harms. Suggestions about how interventions could best respond to the various patterns of use – with special consideration of synthetic cannabinoids (SCs), including how they relate to the use of heroin and the potential for NPSs to operate as a ‘snare’ to more problem use – were also presented.
Limitations
The study was conducted during 2016/17; generalisability beyond this sample and time point is limited. The level of missing data for some of the BYDS analysis was a limitation, as was the fact that the BYDS data were collected in 2011, so in a different context from the data collected during the narrative interviews. The Psychoactive Substances Act 2016 (Great Britain. Psychoactive Substances Act 2016. London: The Stationery Office; 2016) came into force during qualitative fieldwork and, although not particularly influential in this study, may be influential in future work. It is acknowledged that many of the data related to SCs and mephedrone. Although drug use was measured by self-report, the strength of rapport within interviews, reflective diaries and methodological acceptability checks helped to mitigate self-report bias.
Conclusions
NPSs continue to present significant challenges for legislation and monitoring, researching and developing interventions. Understanding of usage patterns remains poor, with most information based on populations and settings where problems have already occurred. This research contributes to the evidence base by providing much needed further empirical data on the lived experiences of NPS users across a range of settings. In the light of these data, implications for policy and practice are discussed.
Future work
Future research must generate improved epidemiological data on the extent, patterns and motivations for use longitudinally. The uniqueness of the information concerning SC use points to a specific set of findings not evidenced in other literature (e.g. intensity of SC withdrawal). Future research should focus on the symbiotic link between SC and heroin use.

Abstract
A survey pertaining to synthetic cathinone (SC) use was completed by 499 polysubstance users enrolled in a residential recovery program in the Southeastern United States. Of the final sample, 28% reported ever SC use. SC-users, compared with nonusers, were more often younger (32.7 vs. 36.0, p = .001), White (93.4% vs. 80.8%, p = .001), and on probation/parole since 2010 (80.9% vs. 70.9%, p = .032). SC-users evidenced extensive drug histories and were less likely to be enrolled in an urban-based program, compared to a rural, Appalachian-based program (73.8% vs. 86.6%, p = .001). Use of synthetic cannabinoids (adjusted odds ratio [AOR] = 1.9, p = .044), kratom (AOR = 1.7, p = .045), and inhalants (AOR = 2.3, p = .001) were significantly associated with SC use. Approximately 23% of SC-users preferred SCs to amphetamines or cocaine; however, only 3.6% ranked SC as their most preferred drug. Past-year SC use declined to 6.6%. Among polysubstance users in this sample, SC use may be a potential indicator of versatile and indiscriminate drug-taking.

Abstract
Recent data suggest that both nonmedical prescription drug and MDMA (ecstasy/molly) use have risen among African Americans. However, studies investigating these two forms of drug use among African Americans are rare. As a result, very little is known about African-American MDMA users and their nonmedical use of prescription medications. The primary goal of this study, therefore, was to describe patterns of nonmedical prescription drug use among African Americans who use MDMA. We also assessed alcohol and illicit drug use among the sample. Surveys (n=100) and in-depth interviews (n=15) were conducted with African-American young adults in Southwest Florida between August 2014 and November 2015. Survey results show that a significant proportion of the sample used MDMA in conjunction with prescription medications (benzodiazepines=59%; opioids=35%; stimulants=13%). Qualitative findings suggest that benzodiazepine medications were used to alleviate MDMA comedown symptoms, opioids were used to achieve a different quality high, and stimulants were used to provide added energy throughout the night. These results suggest that treatment practitioners and harm reduction professionals should pay particular attention to informing users of the potential hazards of combining MDMA with prescription medications. Although additional research is clearly needed, these findings are an important first step towards understanding both nonmedical prescription drug and MDMA use among African Americans, and could be used to tailor treatment and risk reduction interventions to this population.

Abstract
BACKGROUND Ecstasy pills with MDMA as the main ingredient were introduced in many European countries in the 1980s, and were often linked to the rave and club scenes. However, use gradually levelled off, in part as a response to increased concerns about possible mental health consequences and fatalities. Extensive use of MDMA now seems to be re-emerging in many countries. In this study, we investigated the cultural and social meaning associated with MDMA use in Oslo, Norway, with an emphasis on how users distinguish MDMA crystals and powder from "old ecstasy pills". METHODS Qualitative in-depth interviews (n=31, 61,3% males) were conducted with young adult party-goers and recreational MDMA/ecstasy users (20-34 years old, mean age 26.2 years). RESULTS Research participants emphasised three important perceived differences between the MDMA crystals and ecstasy pills: (i) The effects of MDMA were described as better than ecstasy; (ii) MDMA was regarded as a safer drug; (iii) Users of MDMA crystals were described as more distinct from and less anchored in out-of-fashion rave culture than those using ecstasy. These differences were an important part of the symbolic boundary work MDMA users engaged in when justifying their drug use. CONCLUSION MDMA has re-emerged as an important psychoactive substance in Oslo's club scene. One important reason for this re-emergence seems to be its perceived differentiation from ecstasy pills, even though the active ingredient in both drugs is MDMA. This perceived distinction between MDMA and ecstasy reveals the importance of social and symbolic meanings in relation to psychoactive substance use. Insights from this study can be important in terms of understanding how trends in drug use develop and how certain drugs gain or lose popularity.

Abstract
AIMS Failure to complete high school predicts substantial economic and social disadvantage in adult life. The aim of this study was to determine the longitudinal association of mid-adolescent polydrug use and high school non-completion, relative to other drug use profiles. DESIGN A longitudinal analysis of the relationship between polydrug use in three cohorts at grade 9 (age 14-15 years) and school non-completion (reported post-high school). SETTING A State-representative sample of students across Victoria, Australia. PARTICIPANTS A total of 2287 secondary school students from 152 high schools. The retention rate was 85%. MEASUREMENTS The primary outcome was non-completion of grade 12 (assessed at age 19-23 years). At grade 9, predictors included 30-day use of eight drugs, school commitment, academic failure and peer drug use. Other controls included socio-economic status, family relationship quality, depressive symptoms, gender, age and cohort. FINDINGS Three distinct classes of drug use were identified-no drug use (31.7%), mainly alcohol use (61.8%) and polydrug use (6.5%). Polydrug users were characterized by high rates of alcohol, tobacco and cannabis use. In the full model, mainly alcohol users and polydrug users were less likely to complete school than non-drug users [odds ratio (OR) = 1.54, 95% confidence interval (CI) = 1.17-2.03) and OR = 2.51, 95% CI = 1.45-4.33), respectively, P < 0.001]. These effects were independent of school commitment, academic failure, peer drug use and other controls. CONCLUSIONS Mid-adolescent polydrug use in Australia predicts subsequent school non-completion after accounting for a range of potential confounding factors. Adolescents who mainly consume alcohol are also at elevated risk of school non-completion.

Abstract
Though research indicates a complex link between substance use and sexual risk behavior, there is limited research on the association between sexual risk behavior and prescription drug misuse. In light of alarming increases in prescription drug misuse and the role of demographic characteristics in sexual risk behavior and outcomes, the current study examined demographic differences (gender, sexual identity, age, relationship status, parental class background, and race/ethnicity) in sexual risk behavior, sexual behavior under the influence of prescription drugs, and sexual risk behavior under the influence of prescription drugs in a sample of 402 young adults (ages 18 to 29) who misused prescription drugs. Nearly half of the sexually active young adult prescription drug misusers in this sample reported recent sex under the influence of prescription drugs; more than three-quarters reported recent sex without a condom; and more than one-third reported recent sex without a condom after using prescription drugs. Zero-inflated Poisson regression models indicated that White race, younger age, higher parental class, and being a heterosexual man were all associated with sexual risk behavior, sex under the influence of prescription drugs, and sexual risk under the influence of prescription drugs. Findings have implications for the targeting of prevention and intervention efforts.

Uosukainen H, Tacke U, Winstock AR. Self-reported prevalence of dependence of MDMA compared to cocaine, mephedrone and ketamine among a sample of recreational poly-drug users. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2014; 26:78-83. [PMID: 25107829 DOI: 10.1016/j.drugpo.2014.07.004] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2014] [Revised: 07/02/2014] [Accepted: 07/07/2014] [Indexed: 11/30/2022]
Abstract
BACKGROUND Evidence regarding MDMA (ecstasy) dependence and the most suitable criteria for its assessment are controversial. This study aimed to assess the prevalence of last year symptoms of dependence upon MDMA compared to cocaine, mephedrone and ketamine among a large global non-treatment seeking sample. METHODS A cross-sectional anonymous online survey was promoted by a UK-based dance music website between 15 November 2010 and 1 January 2011. Endorsement of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) dependence criteria was sought from all last year users of MDMA, cocaine, mephedrone and ketamine. Reporting ≥3 dependence symptoms was indicative of dependence. Logistic regression models with Generalized Estimating Equations were used to compare dependence symptoms between groups. RESULTS MDMA users were more likely to report ≥3 DSM-IV dependence symptoms compared to users of cocaine (odds ratio OR 0.81, 95% confidence interval CI 0.71-0.93), mephedrone (OR 0.91, 95%CI 0.78-1.06) and ketamine (OR 0.52, 95%CI 0.44-0.62) (p<0.001). MDMA users were less likely to report desire to use less or get help compared to users of other substances (p<0.001). MDMA got the highest rating of pleasurable high (mean 8.2±1.7) and lowest rating for risk of harm (mean 2.7±2.4). CONCLUSIONS Our results highlight the self-reported dependence potential of MDMA but low desire to use less or get help. MDMA's pleasurable effects may compensate for drug-related problems and, therefore, DSM-IV criteria may not be suitable for assessing MDMA dependence. Further research is needed on the ability of DSM-V to assess MDMA dependence.

Abstract
BACKGROUND Alcohol use and illicit drug use peak during young adulthood (around 18-29 years of age), but comparatively little is known about polydrug use in nationally representative samples of young adults. Drawing on a nationally representative cross-sectional survey (Australian National Drug Strategy Household Survey), this study examines polydrug use patterns and associated psychosocial risk factors among young adults (n = 3,333; age 19-29). METHOD The use of a broad range of licit and illicit drugs were examined, including alcohol, tobacco, cannabis, cocaine, hallucinogens, ecstasy, ketamine, GHB, inhalants, steroids, barbiturates, meth/amphetamines, heroin, methadone/buprenorphine, other opiates, painkillers, and tranquilizers/sleeping pills. Latent class analysis was employed to identify patterns of polydrug use. RESULTS Polydrug use in this sample was best described using a 5-class solution. The majority of young adults predominantly used alcohol only (52.3%), alcohol and tobacco (34.18%). The other classes were cannabis, ecstasy, and licit drug use (9.4%), cannabis, amphetamine derivative, and licit drug use (2.8%), and sedative and alcohol use (1.3%). Young adult males with low education and/or high income were most at risk of polydrug use. CONCLUSION Almost half of young adults reported polydrug use, highlighting the importance of post-high school screening for key risk factors and polydrug use profiles, and the delivery of early intervention strategies targeting illicit drugs.

Abstract
This study examines patterns of use of prescription drugs and methamphetamine. We drew our sample from a study about 130 active and inactive methamphetamine users and focused on 16 participants with a recent history of methamphetamine and prescription drug use. We collected in-depth interviews to explore relationships in use trajectory patterns. The qualitative methods we used in this study followed the constant comparison process developed by grounded theory methods and analytical ethnography, which is based on familiarity with the social setting and developing propositions while conducting a research study. We used a triangulation of methods and analysis and included qualitative data, such as participant observation notes and in-depth interviews, as well as quantitative data that we collected in drug history matrices. Five themes emerged from the coding of the interview transcripts: (1) sequential polydrug use; (2) concurrent polydrug use (3) temporary substitution of preferred drug; (4) consequential-based use; and (5) switching from using methamphetamine to using prescription drugs. The trajectory patterns of methamphetamine and prescription drug use complicates treatment significantly.

Abstract
To better understand patterns of drug use trajectories over time, it is essential to have standard measures of change. Our goal here is to introduce measures we developed to quantify change in drug use behaviors. A secondary goal is to provide effective visualizations of these trajectories for applied use. We analyzed data from a sample of 92 older drug users (ages 45 to 65) to identify transition patterns in drug use trajectories across the life course. Data were collected for every year since birth using a mixed methods design. The community-drawn sample of active and former users were 40% female, 50% African American, and 60% reporting some college or greater. Their life histories provided retrospective longitudinal data on the diversity of paths taken throughout the life course and changes in drug use patterns that occurred over time. Bayesian analysis was used to model drug trajectories displayed by innovative computer graphics. The mathematical techniques and visualizations presented here provide the foundation for future models using Bayesian analysis. In this paper we introduce the concepts of transition counts, transition rates and relapse/remission rates, and we describe how these measures can help us better understand drug use trajectories. Depicted through these visual tools, measurements of discontinuous patterns provide a succinct view of individual drug use trajectories. The measures we use on drug use data will be further developed to incorporate contextual influences on the drug trajectory and build predictive models that inform rehabilitation efforts for drug users. Although the measures developed here were conceived to better examine drug use trajectories, the applications of these measures can be used with other longitudinal datasets.

Abstract
This study examines the role that self-esteem plays in HIV-related risk taking among users of the drug, Ecstasy. The first part of the analysis focuses on the relationship of self-esteem to HIV risk-taking. The second part examines predictors of self-esteem in this population. Conducted between 2002 and 2004, the research is based on a sample of 283 young adult Ecstasy users who completed approximately two-hour-long, face-to-face interviews via computer-assisted structured interviews. Study participants were recruited in the Atlanta, Georgia metropolitan area using targeted sampling and ethnographic mapping. Results indicated that self-esteem is associated with a variety of risky practices, including: the number of sex partners that people had, individuals' likelihood of having multiple sex partners, the number of different illegal drugs people used, and their condom use self-efficacy. The multivariate analysis conducted to ascertain the factors that impact participants' levels of self-esteem yielded six factors: educational attainment (positive), coming from a family-of-origin whose members got along well (positive), the extent of alcohol problems (negative), the number of positive effects experienced as a result of Ecstasy use (positive), the number of negative effects experienced as a result of Ecstasy use (negative), and the extent of experiencing symptoms of post-traumatic stress disorder (negative).

Abstract
This study examines drug effect-enhancing behaviors practiced by young adult users of the drug, Ecstasy. Between August 2002 and August 2004, 283 face-to-face interviews were conducted with active Ecstasy users. Study participants were recruited in the Atlanta, Georgia metropolitan area using a targeted sampling approach. The large majority of study participants (87%) engaged in at least one behavior specifically designed to bolster the effects of their Ecstasy use, with 61% of the study participants reporting having engaged in at least three such behaviors during the past 30 days. Taking steps to boost one's Ecstasy-related high was associated with binging on Ecstasy and a variety of adverse outcomes, such as experiencing a greater number of negative consequences resulting from Ecstasy use and experiencing more Ecstasy-related drug dependency symptoms. Multivariate analysis revealed several factors associated with greater involvement in effects-boosting behaviors, including race (not being African American), spending time with other drug users, using Ecstasy for its touch-enhancing qualities, enjoyment of the music-and-Ecstasy-use experience, and childhood maltreatment experiences. The implications of these findings for treatment, prevention, and intervention for drug problems among Ecstasy users are discussed.

Abstract
This paper focuses on past, present, and potential future contributions of ethnographic research to describing and understanding “street cultures” of drug use and the implications these have for informing various interventions. The first section provides an overview of ethnography and drug abuse research. This is followed by a historical perspective on the ethnography of street cultures. Next, the significance of ethnographic drug abuse research is highlighted, with a focus on its methodology. Ethnographic contributions to the development, implementation, and evaluation of interventions are discussed, including ethical issues. Subsequently, the interdisciplinary nature of ethnographic drug abuse research is described. Methodological challenges emerged over time as the definition of street cultures and drug trends shifted. These are illustrated with examples, including the use of prescription drugs, new heroin users, and rural drug and methamphetamine use. The final sections focus on career opportunities for ethnographers and opportunities and barriers for the future. We address training needs for interdisciplinary inquiry, the potential role of ethnographers in prevention and treatment research, and the link to studies on the brain and genetics. The future of ethnographic research on drug use will be influenced by the funding structure. We conclude with a summary of reflections on the past and aspirations for the future.

Abstract
BACKGROUND Ecstasy use has increasingly become popular among young adults, many of whom view it as a safe drug with no or limited negative social and health consequences. In this paper, we explore the perceptions of ecstasy users about its recreational use as well as regarding the normalisation of use. METHODS The study participants were recruited using targeted and theoretical sampling. To be eligible, they had to be between 18 and 25 years and have used ecstasy at least four times within the past 90 days. In-depth interviews were conducted with 112 individuals. Data analysis included the constant comparison method commonly used in modified grounded theory. RESULTS The study participants associated their recreational ecstasy use with control, shaping both the timing and setting of their use. In addition, they supported that easy access/availability and social accommodations of use contributed to their acceptance of ecstasy use as a normal part of life. Moreover, low risk perceptions of the social and health consequences of ecstasy used were identified as resulting in normalisation. CONCLUSION The study findings reveal the importance of considering recreational ecstasy use from the perspective of the users themselves for prevention efforts and when providing social and health services, including intervention strategies. In addition, the potential normalisation of ecstasy use must be considered.
