MDMA/Ecstasy Use Among Young People in Ohio: Perceived Risk and Barriers to Intervention

Evenings with Molly: Adult Couples' Use of MDMA for Relationship Enhancement

Within the modern resurgence of psychedelics as medicinal agents for a range of conditions, the story of MDMA (Ecstasy, Molly) has been re-narrated from a dangerous street drug to a breakthrough mental health therapy. Even still, the story of MDMA remains incomplete within a binary discourse of deviant recreational use versus psychotherapeutic-medical use. The present research aimed to uncover an emerging model of MDMA use grounded in the experiences of adult couples using MDMA privately and in the context of their committed relationships. Eight adult couples who self-reported active MDMA use were recruited for confidential in-depth interviews exploring questions related to drug, set, and setting as a general framework for understanding their private experiences with MDMA. A general inductive coding process was used to arrive at four overarching themes: Conscious Use, A Tool for Exploring, Planned Recovery, and Difficult Experiences. Couples reported making purposeful decisions about MDMA use, collaborating together on becoming physically and emotionally "set" for their drug experience. Couples described positive effects on communication, intimate bonding, and providing a relationship "tune up," among other durable changes to the relationship. An emerging cognitive-relational model of "evenings with Molly" contrasts with existing models of use by suggesting the possibility of informed, non-problematic adult use of the drug for cognitive and relational enhancement. With a small, homogenous sample reporting generally positive experiences with MDMA self-administration, findings from this study cannot be generalized. It remains unknown what proportion of the total MDMA user population might align with the non-problematic adult use of MDMA explored in this study. Additional focused investigations might examine the prevalence and varieties of non-clinical use among adults in order to arrive at rational, science-based regulatory frameworks.

Perceptions of drug users and community gate keepers on the causes and consequences of synthetic drug use in Kunming: A three-level social-ecological approach

Synthetic drug use (SDU) is on the rise in China. Utilizing a grounded three-level social-ecological theoretical model, we aim to better understand how users, medical professionals, and other community gatekeepers perceive the causes and consequences of synthetic drug use in Kunming, China. Past work typically relies on drug users confined to rehabilitation facilities. Utilizing qualitative methods, our work integrates how various community actors perceive problems around synthetic drug use. Thirty face-to-face interviews were conducted in Kunming that were audio-recorded and transcribed. We identify emergent personal, interpersonal and societal level themes shaping SDU which provided our grounded theoretical model. Regardless of their social position, informants identified curiosity, peer networks that facilitated exposure, and the communality of sharing the drug experience as reasons to try synthetic drugs. Drug users reported negative consequences of SDU including the inability to sleep, a fear that others might discover one was using, and the difficulty of quitting. Medical professionals and others in the community were more likely to identify potential harms of SDU. Still, these community members felt synthetic drugs were less problematic than traditional drugs and reported less prejudice and stigma about these new drugs. Overall, medical professionals felt ill-prepared to deal with this new epidemic.

A randomized trial of brief assessment interventions for young adults who use drugs in the club scene

BACKGROUND

Efficacious interventions to reduce drug use and its consequences for club drug using populations are not apparent in the literature. We tested interviewer- (CAPI) and self-administered (ACASI) comprehensive health and social risk assessments as distinct interventions compared to waitlist control.

METHODS

750 men and women ages 18-39 with multidrug use and heterosexual behavior were randomized in equal proportions to the three conditions. Instrumentation included well-tested measures of drug use, risky sex, mental distress and substance dependence.

RESULTS

The sample was 56% male; mean age=25. Reported risk behaviors and health consequences did not differ by assessment modality. Adjusted HLM analyses showed a significant main effect of assigned condition on all outcomes. CAPI participants had greater reductions in drug use, risky sex, mental distress and substance dependence symptoms, and greater increases in abstinence, compared to ACASI intervention or control participants at 12months, except that the CAPI and ACASI conditions had similar efficacy for reductions in drug use. Effect sizes for CAPI versus ACASI participants were d=0.2-0.3, and between CAPI and controls d=0.2-0.4. Effect sizes for improved outcomes between ACASI compared to controls were small to non-significant.

CONCLUSIONS

The study established the therapeutic benefit of interviewer interaction in reducing risky behavior among this young drug using population. The study demonstrated the efficacy and acceptability of a low threshold intervention in reducing drug use, sexual risk and related co-morbidities among a not-in-treatment young adult population that exhibits severe and complex levels of drug use, but that is also highly resistant to intervention.

From "herbal highs" to the "heroin of cannabis": Exploring the evolving discourse on synthetic cannabinoid use in a Norwegian Internet drug forum

BACKGROUND

In the early 2000s, online vendors began selling an array of so-called "legal highs"--apparently organic produce made from exotic herbs. Simultaneously, members of online drug discussion forums began to debate the alleged effects of the new drugs, creating an enormous base of user-derived information based on personal experiences.

METHODS

This study combines the historical data spanning a seven-year period derived from a Norwegian drug discussion forum about synthetic cannabinoids and interviews with 14 male forum members who all had experience with the drug. By combining the two sources, this study reveals not only the evolving discourse on synthetic cannabinoid use but also how forum members related to the online information that they gathered and co-produced.

RESULTS

Analysis of the evolving online discourse revealed three distinct phases. The first was an enthusiastic phase, with users embracing the new drugs. The second was a phase characterized by growing ambivalence and scepticism towards use of the drugs. The third was one in which members of the community rejected the new drugs based on negative reviews from users.

CONCLUSION

The analysis displays the communal process whereby members co-operate in the exchange of an extensive body of knowledge accumulated about synthetic cannabinoids, and the way in which this evolving discourse influences members of the forum in their views and representations of the drugs. Paradoxically, the online discussions of synthetic cannabinoids, which had great significance for their proliferation when they were initially introduced to the market, now seem to be a deterrent. The role of online drug communities in the development of new drug trends should receive renewed attention.

Brief interventions to reduce Ecstasy use: a multi-site randomized controlled trial

Studies examining the ability of motivational enhancement therapy (MET) to augment education provision among ecstasy users have produced mixed results and none have examined whether treatment fidelity was related to ecstasy use outcomes. The primary objectives of this multi-site, parallel, two-group randomized controlled trial were to determine if a single-session of MET could instill greater commitment to change and reduce ecstasy use and related problems more so than an education-only intervention and whether MET sessions delivered with higher treatment fidelity are associated with better outcomes. The secondary objective was to assess participants' satisfaction with their assigned interventions. Participants (N=174; Mage=23.62) at two Australian universities were allocated randomly to receive a 15-minute educational session on ecstasy use (n=85) or a 50-minute session of MET that included an educational component (n=89). Primary outcomes were assessed at baseline, and then at 4-, 16-, and 24-weeks postbaseline, while the secondary outcome measure was assessed 4-weeks postbaseline by researchers blind to treatment allocation. Overall, the treatment fidelity was acceptable to good in the MET condition. There were no statistical differences at follow-up between the groups on the primary outcomes of ecstasy use, ecstasy-related problems, and commitment to change. Both intervention groups reported a 50% reduction in their ecstasy use and a 20% reduction in the severity of their ecstasy-related problems at the 24-week follow up. Commitment to change slightly improved for both groups (9%-17%). Despite the lack of between-group statistical differences on primary outcomes, participants who received a single session of MET were slightly more satisfied with their intervention than those who received education only. MI fidelity was not associated with ecstasy use outcomes. Given these findings, future research should focus on examining mechanisms of change. Such work may suggest new methods for enhancing outcomes. Australia and New Zealand Clinical Trial Registry: ACTRN12611000136909.

Perceived risk of methamphetamine among Chinese methamphetamine users

BACKGROUND

Methamphetamine use has grown considerably in China in recent years. Information about perceptions of risk on methamphetamine is important to facilitate health promotion efforts.

METHODS

Using both survey data and qualitative interview data, the authors evaluate the perceived risk of methamphetamine use among Chinese users using a mixed-methods approach. Through Respondent Driven Sampling, the authors recruited a sample of 303 methamphetamine users in Changsha, China.

RESULTS

A majority (59.1%) perceive that infrequent methamphetamine use poses no risk to the user, while 11.2% perceive at least moderate risk for light use. A majority (56.7%) perceived at least moderate risk associated with regular methamphetamine use. Most (82.2%) also perceive methamphetamine to be easily obtainable. A path model indicates that perceived risk shapes intentions to use and expectations of future use, as does perceived availability. Qualitatively, while addiction was the most common risk discussed by users, they differed on whether they perceived the drug addictive. Other concerns raised by interviewees included impaired cognition, mental health problems, physical harm, and social dysfunction.

CONCLUSION

While some users identify significant risks with methamphetamine, others do not perceive its use to be problematic. Collectively, these findings indicate that intervening upon perceptions of risk among Chinese methamphetamine users may be a means to influence intentions to use.

Interview as intervention: the case of young adult multidrug users in the club scene

This paper reports on changes in substance use and substance dependence symptoms-without intervention-among young adult multidrug users in the club scene, ages 18-29, (N = 444) who participated in a natural history study. Computer-assisted personal interviews at baseline and 6-, 12-, and 18-month follow-ups included well-tested measures of substance use and dependence. Changes in substance dependence symptoms and drug use frequencies were calculated using Cohen's d statistic. Mean age was 22; 40% were female; 58% were Hispanic, 17% White, and 21% Black. At 18-month follow-up assessment, participants reported significantly fewer days of cocaine (d = -.85 at 18 months), ecstasy (d = -.93), benzodiazepine (d = -.82), and prescription opioid (d = -.81) use, as well as reduced substance dependence symptoms (d = -.42). These results, together with data from focus groups with completers, suggest that comprehensive health and social risk assessments may have quite strong intervention effects among young adult multidrug users.

"I'm not afraid of those ones just 'cause they've been prescribed": perceptions of risk among illicit users of pharmaceutical opioids

BACKGROUND

There has been a rise in the illicit use of pharmaceutical opioids ("pain pills") in the United States. Conducted with young adult non-medical users of pharmaceutical opioids, this study uses qualitative methods and cultural consensus analysis to describe risk perceptions associated with pharmaceutical opioids and to determine patterns of cultural sharing and intra-cultural variation of these views.

METHODS

The qualitative sub-sample (n=47) was selected from a larger sample of 396 young adults (18-23 years old), who were participating in a natural history study of illicit pharmaceutical opioid use. Qualitative life history interviews, drug ranking task, and cultural consensus analysis were used to elicit participant views about risks and harms associated with pain pills and other drugs, as well as alcohol and tobacco.

RESULTS

Cultural consensus analysis revealed that the participants shared a single cultural model of drug risks, but the level of agreement decreased with the increasing range of drugs ever used. Further, those with more extensive drug use histories differed from less "experienced" users in their views about OxyContin and some other drugs. Overall, pain pills were viewed as addicting and potentially deadly substances, but these properties were linked to the patterns and methods of use, as well as characteristics of an individual user. Further, risks associated with pharmaceutical opioids were further curtailed because they "came from the doctor," and thus had a legitimate aspect to their use.

CONCLUSIONS

This study highlights potential problems with universal approaches to substance use prevention and intervention among young people since such approaches ignore the fact that substance use education messages may be experienced differently depending on an individual's drug use history and his/her perceptions of drug risks. Findings reported here may be useful in the development of prevention and intervention programs aimed at reducing the harm associated with illicit use of pain pills.

Perceived risk associated with ecstasy use: a latent class analysis approach

This study aims to define categories of perceived health problems among ecstasy users based on observed clustering of their perceptions of ecstasy-related health problems. Data from a community sample of ecstasy users (n=402) aged 18 to 30, in Ohio, was used in this study. Data was analyzed via Latent Class Analysis (LCA) and Regression. This study identified five different subgroups of ecstasy users based on their perceptions of health problems they associated with their ecstasy use. Almost one third of the sample (28.9%) belonged to a class with "low level of perceived problems" (Class 4). About one fourth (25.6%) of the sample (Class 2), had high probabilities of "perceiving problems on sexual-related items", but generally low or moderate probabilities of perceiving problems in other areas. Roughly one-fifth of the sample (21.1%, Class 1) had moderate probabilities of perceiving ecstasy health-related problems in all areas. A small proportion of respondents (11.9%, Class 5) had high probabilities of reporting "perceived memory and cognitive problems", and of perceiving "ecstasy-related problems in all areas" (12.4%, Class 3). A large proportion of ecstasy users perceive either low or moderate risk associated with their ecstasy use. It is important to further investigate whether lower levels of risk perception are associated with persistence of ecstasy use.

Thizzin'-Ecstasy use contexts and emergent social meanings

The drug "Ecstasy" has been most commonly associated with raves, or electronic music dance events, and attributed with sexual disinhibition. In an ethnographic investigation of drug use among second-generation Southeast Asian youth in Northern California (2003), respondents described little use of or interest in using Ecstasy; yet in a second study, Ecstasy was the fourth most commonly-used substance. This paper investigates the social contexts for this change in use patterns. Respondents were second-generation Southeast Asian youths and young adults between the ages of 15 and 26 who were currently or recently drug-involved. We compared qualitative data from the two studies and found emerging patterns of meaning and context related to the observed change in use patterns. Ecstasy use among co-resident African American youth within the context of the local "hyphy" hip-hop music subculture had influenced Southeast Asian youths' uptake of the drug, known as "thizz." Respondents referred to the effects of the drug as "thizzin'," described as energizing, disinhibiting, numbing, and emotion enhancing. Reported consequences of "thizzin'" included violence and aggression as well as fun, while sexual disinhibition was rarely mentioned. The meanings assigned to drugs, including the effects ascribed to them, may be relative to the social contexts within which users are exposed to and consume drugs. The findings indicate the susceptibility of youths to local trends in drug use, particularly associated with popular cultural movements and music. Second-generation youths may be particularly susceptible relative to the conditions of their immigration and processes of identity formation unique to them.

Negotiating ecstasy risk, reward, and control: a qualitative analysis of drug management patterns among ecstasy-using urban young adults

This paper is based on qualitative in-depth interviews conducted from 2008 to 2009 with 118 ethnically diverse Ecstasy users from the greater Hartford area, CT, USA. Participants were urban, primarily Black and Hispanic, aged 18 to 36, and had limited higher education compared with samples in previous Ecstasy research. Interviews focused on personal background, history of Ecstasy and other drug use, and recent sexual events. In this paper, we examine: participants' negotiation of perceived risks and benefits of Ecstasy use, behavioral strategies employed to minimize risks, and the relationship of risk-benefit analysis, motivation for use, frequency of use, and polydrug use to participants' sense of control over their Ecstasy use. We conclude with recommendations for intervention approaches and suggestions for future research.

The impact of positive and negative ecstasy-related information on ecstasy use among college students: Results of a longitudinal study

AIMS: To: 1) estimate the proportion of students exposed to specific types of information regarding the positive and negative effects of ecstasy, 2) test models that quantified the relationship between exposure to these messages and subsequent ecstasy use, controlling for peer drug use and sensation-seeking. METHODS: As part of the College Life Study, 447 students, ages 17-20, from a university in the mid-Atlantic region of the US completed an in person interview plus three follow-up assessments. FINDINGS: Individuals who had heard a greater number of negative messages were significantly more likely to use ecstasy, even controlling for positive messages, prior ecstasy use, peer ecstasy use, perceived harm, sensation-seeking, sex, and race. Some messages were significant at the bivariate level. CONCLUSIONS: Ecstasy use may have been influenced more by the content of the messages than by the quantity or diversity of messages. Interventions should be designed to address both positive and negative perceptions about a particular drug, rather than focusing exclusively on the negative information. Future evaluations should focus on the effectiveness of multi-pronged sustainable prevention programs in reducing adolescent drug use risk.

Modifiable risk factors of ecstasy use: risk perception, current dependence, perceived control, and depression

Risk perception, perceived behavioral control of obtaining ecstasy (PBC-obtaining), current ecstasy dependence, and recent depression have been associated with past ecstasy use, however, their utility in predicting ecstasy use has not been demonstrated. This study aimed to determine whether these four modifiable risk factors could predict ecstasy use after controlling for socio-demographic covariates and recent polydrug use. Data from 601 ecstasy users in the National Institute on Drug Abuse-funded TriCity Study of Club Drug Use, Abuse and Dependence were analyzed using multivariate logistic regression. Participants were interviewed twice within a 2-week period using standardized instruments. Thirteen percent (n = 80) of the participants reported using ecstasy between the two interviews. Low risk perception, high PBC-obtaining (an estimated ecstasy procurement time < 24h), and current ecstasy dependence were statistically associated with ecstasy use between the two interviews. Recent depression was not a significant predictor. Despite not being a target predictor, recent polydrug use was also statistically associated with ecstasy use. The present findings may inform the development of interventions targeting ecstasy users.

A structured review of reasons for ecstasy use and related behaviours: pointers for future research

BACKGROUND

While the health risks of using ecstasy warrant intervention development, a recent meta-analysis of determinants of ecstasy use identified a number of lacunae in the literature. Specifically, no studies were included that address behaviours other than 'using ecstasy' (e.g. 'trying out ecstasy' or 'ceasing ecstasy use'). However, because meta-analyses aim to integrate study results quantitatively, the resulting rigid exclusion criteria cause many studies to be discarded on the basis of their qualitative methodology. Such qualitative studies may nonetheless provide valuable insights to guide future research. To provide an overview of these insights regarding ecstasy use, the current study summarizes and combines what is known from qualitative and exploratory quantitative literature on ecstasy use.

METHODS

The databases PsycINFO and MedLine were searched for publications reporting reasons for ecstasy use and related behaviour, and the results were structured and discussed per behaviour and compared over behaviours.

RESULTS

Two main categories of reasons were found. The first category comprised reasons to start using ecstasy, use ecstasy, use ecstasy more often, and refrain from ceasing ecstasy use. The second category comprised reasons to refrain from starting to use ecstasy, use less ecstasy, and cease using ecstasy. Reasons for related behaviours within each of these two categories appear to differ, but not as substantially as between the two categories. A large number of reasons that were not yet explored in quantitative research emerged.

CONCLUSION

The current summary and combination of exploratory studies yields useful lists of reasons for each behaviour. Before these lists can inform interventions, however, they beg quantitative verification. Also, similarity of determinant configurations of different behaviours can be assessed by addressing determinants of several behaviours in one study. Another important finding is that meta-analytical integration of the literature may overlook important findings and implications. Thus, qualitative reviews remain useful instruments in setting the research agenda.

Careers in ecstasy use: do ecstasy users cease of their own accord? Implications for intervention development

Background

Ecstasy (MDMA, 3, 4-methylenodioxymethamphetamine) use is widespread in the Netherlands, with a lifetime prevalence of 4.3%, and two-thirds of dance party visitors being ecstasy users. However, research into Dutch ecstasy use patterns is lacking. In addition, recent studies suggest that ecstasy users cease their use automatically, which implies that interventions would do better to better focus on the promotion of harm reduction strategies than on inducing cessation. The current study addresses this process of ecstasy cessation.

Methods

32 participants from the Dutch dance scene were interviewed, and the results were systematically analysed using NVivo.

Results

Most ecstasy users had started to use out of curiosity. During use, users applied a host of harm reduction strategies, albeit inconsistently and sometimes incorrectly. Most users appeared to cease ecstasy use automatically because of loss of interest or changing life circumstances (e.g. a new job or relationship).

Conclusion

It appears that cessation of ecstasy use is largely determined by environmental variables and not by health concerns. This supports the idea that health promotion resources are better spent in trying to promote consistent and correct application of harm reduction practices than in trying to induce cessation.

Do adolescent ecstasy users have different attitudes towards drugs when compared to marijuana users?

BACKGROUND

Perceived risk and attitudes about the consequences of drug use, perceptions of others expectations and self-efficacy influence the intent to try drugs and continue drug use once use has started. We examine associations between adolescents' attitudes and beliefs towards ecstasy use; because most ecstasy users have a history of marijuana use, we estimate the association for three groups of adolescents: non-marijuana/ecstasy users, marijuana users (used marijuana at least once but never used ecstasy) and ecstasy users (used ecstasy at least once).

METHODS

Data from 5049 adolescents aged 12-18 years old who had complete weighted data information in Round 2 of the Restricted Use Files (RUF) of the National Survey of Parents and Youth (NSPY). Data were analyzed using jackknife weighted multinomial logistic regression models.

RESULTS

Adolescent marijuana and ecstasy users were more likely to approve of marijuana and ecstasy use as compared to non-drug using youth. Adolescent marijuana and ecstasy users were more likely to have close friends who approved of ecstasy as compared to non-drug using youth. The magnitudes of these two associations were stronger for ecstasy use than for marijuana use in the final adjusted model. Our final adjusted model shows that approval of marijuana and ecstasy use was more strongly associated with marijuana and ecstasy use in adolescence than perceived risk in using both drugs.

CONCLUSION

Information about the risks and consequences of ecstasy use need to be presented to adolescents in order to attempt to reduce adolescents' approval of ecstasy use as well as ecstasy experimentation.

Social cognitive determinants of ecstasy use to target in evidence-based interventions: a meta-analytical review

AIMS

The health hazards and prevalence of ecstasy use have been documented in two decades of research, but no review reporting on potentially modifiable antecedents of use is available. The aim of this study was to integrate systematically research identifying cognitive correlates of ecstasy use. Such research has the potential to identify targets for evidence-based interventions designed to discourage use.

METHODS

The databases PsycINFO and MedLine were searched, inclusion criteria applied to resulting hits, and descendency and ancestry approaches applied to the selected publications. Reported associations between cognitive determinants, including intention to use and ecstasy use measures, were synthesized by calculating a weighted mean effect size, r.

RESULTS

The pattern of associations lent support both to the theory of planned behaviour (TPB) and the expectancy approach as descriptions of potentially useful determinants. Attitudes were associated most strongly with intention and use, followed by subjective norm and perceived behavioural control.

CONCLUSIONS

Consideration of the strength of associations and the potential modifiability of identified cognitions suggests that evidence-based interventions to discourage ecstasy use should target negative expectancies, perceived behavioural control and anticipated regret, and consider tailoring perceived behavioural control elements.

Maximising the highs and minimising the lows: harm reduction guidance within ecstasy distribution networks

BACKGROUND

Little is known about how users build and share knowledge concerning the highs and lows of Ecstasy and the role that Ecstasy sellers play in the exchange of this information.

METHODS

These findings are based on a National Institute on Drug Abuse-funded project, "An Exploratory Study of Ecstasy Distribution," conducted between 2003 and 2006. We completed in-depth interviews with 120 men and women in the San Francisco Bay Area who had sold 5 or more doses 5 or more times in the 6 months prior to the interview. The research focused on buyer-seller relationships and the influence of these relationships on users' health.

RESULTS

Users constructed harm reduction strategies in attempts to maximise the Ecstasy high and minimise the risks. The social context of Ecstasy use allowed for the exchange of harm reduction information and advice on how to maximise the pleasurable aspects of Ecstasy. Some participants served as "guides" to ensure that their customers had safe and enjoyable experiences while using Ecstasy.

CONCLUSION

These findings suggest that Ecstasy sellers are important points of intervention for the dissemination of harm reduction information as friendship networks were the primary link in creating awareness of safer Ecstasy use.

Psychiatric disorders and their correlates among young adult MDMA users in Ohio

This study describes the lifetime prevalence, correlates, and age of onset of selected psychiatric disorders among a community sample of MDMA users (n = 402), aged 18 to 30, in Ohio. Participants responded to interviewer-administered questionnaires, including sections of the computerized Diagnostic Interview Schedule for DSM-IV. Fifty-five percent of the sample had at least one lifetime disorder, with major depression (35.3%) and antisocial personality disorder (ASPD) (25.4%) the most common. Proportionately more women were diagnosed with depression, generalized anxiety disorder, and posttraumatic stress disorder (PTSD), while proportionately more men were diagnosed with ASPD. Proportionately more non-White participants had attention deficit/hyperactivity disorder (AD/HD). Higher levels of education were associated with proportionately less PTSD, ASPD, and AD/HD. Higher frequencies of MDMA use were associated with proportionately more ASPD and AD/HD. Comparing the age of first MDMA use with the age of onset for selected psychiatric disorders revealed that for most participants disorders preceded use. Multivariate analysis revealed participants with more than a high school education were less likely to have experienced a lifetime disorder, while those who had used MDMA more than 50 times were more likely. Variations in the prevalence of psychiatric disorders have practical implications for drug abuse prevention and treatment programs.

Prevalence and correlates of current depressive symptomatology among a community sample of MDMA users in Ohio

Research suggests that MDMA can cause serotonin depletion as well as serotonergic neurodegradation that may result in depression among users of the drug. Several small-scale studies have used various editions of the Beck Depression Inventory (BDI) to quantify depressive symptomatology among MDMA users. This study represents the largest application of the BDI to date to explore symptoms of current depression among a community sample of young adult MDMA users (n = 402). Internal consistency testing of the BDI-II with this sample revealed Cronbach's alpha = .92. Results show a mean BDI-II score of 9.8, suggesting low levels of depressive symptomatology among study participants. Two-thirds of the sample had scores that placed them in the non-depressed/minimal depression category, while 4.7% had scores indicative of severe depression. Logistic regression analysis revealed that men were significantly less likely than women and people who used opioids were significantly more likely than non-users to have higher levels of depressive symptomatology. Higher lifetime occasions of MDMA use were marginally related to symptoms of serious depression.

Drug use practices among MDMA/ecstasy users in Ohio: a latent class analysis

This study describes the drug use practices among 402 recent MDMA (3,4-methelyenedioxymethamphetamine) users recruited in Ohio using respondent-driven sampling. About 64% of the participants were men, 81.6% were white, and the mean age was 20.9 years. Latent class analysis was used to identify subgroups of MDMA users. Use of cocaine, opioids, amphetamines, tranquilizers, inhalants, marijuana, and hallucinogens during the previous 6 months, and days of "drunkenness" in the past 30, were used for classification. A three-class model was preferable and reflected "Limited range," "Moderate range," and "Wide range" drug use patterns. For example, the conditional probability of using opioids during the previous 6 months was .07 in Class 1, .59 in Class 2, and .88 in Class 3. Other substances followed similar patterns. Predictors of class membership were examined in a multinomial logit model in which the "Limited range" Class was treated as the reference group. Participants who were white, younger, and who reported more than 10 occasions of MDMA use were more likely to be in the "Wide range" drug use Class. Latent class analysis is a useful method to help describe and understand variability in polydrug use patterns.

Chronic tolerance to recreational MDMA (3,4-methylenedioxymethamphetamine) or Ecstasy

This review of chronic tolerance to MDMA (3,4-methylenedioxymetamphetamine) covers the empirical data on dosage escalation, reduced subjective efficacy and bingeing in recreational Ecstasy users. Novice users generally take a single Ecstasy tablet, regular users typically take 2-3 tablets, whereas the most experienced users may take 10-25 tablets in a single session. Reduced subjective efficacy following repeated usage is typically described, with many users subjectively reporting the development of tolerance. Intensive self-administration or bingeing is often noted by experienced users. This can comprise 'stacking' on several tablets together, and 'boosting' on successive doses over an extended period. Some experienced users snort Ecstasy powder nasally, whereas a small minority inject MDMA. Chronic tolerance and bingeing are statistically linked to higher rates of drug-related psychobiological problems. In terms of underlying mechanisms, neuroadaptive processes are certainly involved, but there is a paucity of evidence on hepatic and behavioural mechanisms. Further studies specifically designed to investigate chronic tolerance, involving low intermittent dose regimens, are required. Most animal research has involved intensive MDMA dosing regimens designed to engender serotonergic neurotoxicity, and this may comprise another underlying mechanism. If distal serotonin axon terminal loss was also developing in recreational users, it may help to explain why reducing subjective efficacy, dosage escalation and increasing psychobiological problems often develop in parallel. In conclusion, there is extensive evidence for chronic pharmacodynamic tolerance to recreational Ecstasy/MDMA, but the underlying mechanisms are currently unclear. Several traditional processes are probably involved, but one of the possible causes is a novel mechanism largely unique to the ring substituted amphetamine derivatives, namely serotonergic neurotoxicity.

"Rollin' on E": a qualitative analysis of ecstasy use among inner city adolescents and young adults

Ecstasy use has spread beyond the rave and club scenes into other arenas of party culture, and from middle-class America to working-class and low-income neighborhoods of large cities. In order to explore ecstasy use among inner city adolescents and young adults, we conducted in-depth interviews with 23 poly-drug users who had used ecstasy, in Hartford, CT. Most users reported positive experiences while on the drug. Negative experiences were most often related to poly-drug mixing. However, heavy users (40+ times ever used) experienced negative aftereffects, which led them to decide to decrease or halt their use. Some participants discussed using ecstasy during sex, and irregular use of condoms. These findings point to the need for more in-depth research on MDMA use within inner city settings, with a particular focus on ethnic and cultural context, self-controlled drug use, poly-drug mixing, and sex risk behaviors.

Sources of information about MDMA (3,4-methylenedioxymethamphetamine): perceived accuracy, importance, and implications for prevention among young adult users

The goal of this cross-sectional study was to assess the perceived accuracy and the importance of various sources of information about MDMA/ecstasy among young adult users. A respondent driven sampling plan was used to recruit a community sample of recent ecstasy users (n = 304), aged 18-30, in Ohio, who responded to structured interviews. Friends, drug abuse treatment programs, and physicians were perceived to be the most accurate sources of information about ecstasy by 45.7, 37.2, and 30.3% of the sample, respectively. Friends were considered the most important source of information about ecstasy (40.2%), followed by web sites like DanceSafe (16.2%), and MTV/VH1 television specials (6.9%). About half the sample used the Internet to obtain information about ecstasy, with younger and more educated participants significantly more likely to do so. Educated users were also significantly more likely to consider the Internet to be an important source of information. Web sites like DanceSafe were visited by four times as many users as government-sponsored web sites. Findings support the development of peer-oriented, network strategies to reach ecstasy users with prevention messages. Efforts to make prevention web sites more attractive should be considered.
