RESUMO
BACKGROUND: Club drug use-including 3,4-Methylenedioxymethamphetamine, ketamine, crack/cocaine, hallucinogens, gamma hydroxybutyrate, volatile nitrites, and methamphetamine-has been linked to sexual risk behaviors among MSM. Few studies examine how the use of club drugs and the association between club drug use during sex and sexual risk may differ by race/ethnicity. METHODS: Using data from a cross-sectional study among alcohol-using MSM in San Francisco (n = 252), we examined the associations between the interaction of race/ethnicity and club drug use during sex, and the following behavioral outcomes: any condomless anal intercourse (CAI), insertive CAI, receptive CAI, and any serodiscordant sex in the past six months. All models controlled for income, HIV status, relationship status, age, and current use of a biomedical HIV prevention tool (i.e., Pre-Exposure Prophylaxis [PrEP] or antiretroviral therapy). RESULTS: There were significant racial differences in club drug use (p < 0.001) and club drug use during sex (p = 0.01). Asian/Pacific Islander (API) and Latino participants reported using club drugs the most at 78.8% and 79%, respectively. Among users of club drugs, club drug use during sex was most common among Black (100%), and Latino MSM (93%). Significant interactions between race/ethnicity and club drug use during sex were observed for CAI (p = 0.02), insertive CAI (p = 0.01), and receptive CAI (p = 0.01). API participants who used club drug during sex had higher odds of reporting CAI (aOR = 15.27, CI = 1.50-155.34), insertive CAI (aOR = 21.11, CI = 2.04-218.10), and receptive CAI (aOR = 21.11, CI = 2.04-218.10). CONCLUSIONS: Given the differing rates of club drug use during sex by race/ethnicity and the role race/ethnicity plays in modifying the relationships between club drug use during sex and sexual risk behaviors, culturally-tailored interventions may be needed to address the needs of ethnically-diverse, club drug-using MSM.

OBJECTIVE: To investigate associations between reported eating disorder (ED) diagnosis and substance use disorder (SUD) diagnosis, substance misuse, and illicit drug use among US college students. METHOD: Data consisting of n = 414,299 students' responses to the National College Health Assessment survey conducted by the American College Health Association between fall 2015 and spring 2019 were utilized for this study. Unadjusted and adjusted odds ratios were used to determine the association of reported ED diagnosis with reported SUD diagnosis, misuse of cigarettes, e-cigarettes, alcohol, marijuana, cocaine/methamphetamine, sedatives, hallucinogens, opiates, inhalants, MDMA, and other club drugs, as well as illicit use of prescription pain killers, prescription sedatives, and prescription stimulants. A sensitivity analysis investigating associations between reported anorexia nervosa (AN), bulimia nervosa (BN), and each substance use outcome was also conducted. RESULTS: Among all in our analytic cohort, 7.15% reported receiving an ED diagnosis or being treated for an ED in the last 12 months. Students with ED indications were significantly more likely to report each of the substance use outcomes investigated in this study, including SUD diagnosis (aOR: 7.43; 95% CI: 6.98, 7.92; p < .0001), opiate misuse (aOR: 8.35; 95% CI: 7.38, 9.45; p < .0001), and misuse of other club drugs (aOR: 10.37; 95% CI: 9.10, 11.81; p < .0001) than peers without reported EDs. Both AN and BN were associated with an increased likelihood of SUD diagnosis. DISCUSSION: These findings demonstrate strong associations between EDs and the most extensive list of substance use outcomes explored in the context of college setting ED research to date.

A drug concoction called tusi has emerged in Latin America and in Europe and is now beginning to acquire popularity in the United States. "Tusi" is a phonetic translation of "2C," a series of psychedelic phenethylamines. The concoction is also sometimes referred to as "pink cocaine" as it typically comes in the form of pink powder. However, despite its name, the concoction rarely contains 2C series drugs. Multiple drug checking studies have found that the majority of tusi samples contain ketamine, often combined with 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine, cocaine, opioids, and/or new psychoactive substances. The tusi phenomenon complicates the drug landscape because it has the potential to confuse both people who use it and researchers alike. People using may think the drug is 2C/2C-B, and they may also be unaware that the concoction tends to consist of ketamine and a wide variety of other drugs. Unintentional exposure to its contents can lead to increased risk of adverse effects. The tusi phenomenon also has the potential to complicate drug research as unknown exposure to drugs like ketamine and MDMA will lead to underreporting of use. A combination of self-report and toxicological testing may be needed to inform the most accurate estimates of use. Both researchers and people at risk for use need to be informed about this new concoction. Drug researchers need to be cognizant about the way they query use, and people at risk for using need to be educated about the possible contents of tusi and associated dangers.

BACKGROUND: Over the last decade, rates of fentanyl-related overdoses have increased substantially across North America, a phenomenon which has widely been described as the "fentanyl epidemic." While research has explored the cultural impact of the fentanyl epidemic on opioid and/or injection drug use, less is known about its impact on other types of drug use. Drawing on two years of ethnographic research with people who use club drugs in Toronto's Electronic Dance Music (EDM) scene, this study looks at how people who use club drugs make sense of and respond to the fentanyl epidemic. METHODS: Data for the study was collected via participant observation and semi-structured interviews (n = 26). FINDINGS: The key finding was that fentanyl contamination had become a "risk priority" for the participants. They thereby adjusted their drug-using behaviors to account for this risk. However, by prioritizing fentanyl contamination above everything else, they often overlooked and/or disregarded other forms of harm reduction that they had once practiced (like getting testing kits to test for other adulterants). CONCLUSION: The findings suggest that the fentanyl epidemic has impacted not only practices of illegal opioid use, but also practices of club drug use. They suggest that the fentanyl epidemic has in some ways facilitated the adoption of risk management, while in other ways undermined it. The findings are interpreted with reference to Rhodes' "risk environment" framework and with particular attention to the need for harm reduction interventions that take into consideration how risk perceptions and behaviors are situation- and context-dependent.

BACKGROUND: Early onset of drug use could lead to long-term impairments, and research suggests that substance use and substance use disorders are more common among lesbian, gay, and bisexual (LGB) individuals. We sought to determine whether adults of different sexual identities were at differential risk for an earlier onset of drug use. METHODS: We examined data from adults participating in the five waves (2015-2019) of the National Survey on Drug Use and Health, a nationally representative sample of noninstitutionalized adults in the United States. We determined whether current sexual identity was associated with retrospectively reported age of the first use of marijuana, cocaine, inhalants, ecstasy, and methamphetamine. RESULTS: Compared to heterosexual individuals of the same sex, gay men had a later age of onset of use of all five drugs examined (marijuana, cocaine, inhalants, ecstasy, and methamphetamine) and bisexual men had a later onset of marijuana and inhalant use. Bisexual women had earlier age of onset for marijuana, cocaine, and ecstasy use. When examining early initiation (prior to age 15), both lesbian and bisexual women had greater odds of early initiation for marijuana, cocaine, and ecstasy; bisexual men had greater odds of early initiation for cocaine. Gay men had lower odds of initiation prior to age 15 for marijuana, inhalants, and methamphetamine. CONCLUSIONS: Current sexual identity is a correlate of earlier onset drug use. Longitudinal research is needed to further examine such associations as sexual identity can shift over time. Results are discussed in relation to prevention efforts aiming younger LGB persons.

Background: Research on the efficacy of ketamine in treating depression and 3,4-methylenedioxymethamphetamine (MDMA) in treating post-traumatic stress disorder have been widely covered by the media. Given recent widespread coverage of the efficacy of these drugs, it is important to determine whether such coverage influences prevalence of recreational use. While longitudinal studies would be most ideal for assessing this, to acquire preliminary data, we tested survey items assessing this potential phenomenon in a population known for high prevalence of use of these drugs. Method: Adults entering randomly selected nightclubs in New York City (n = 209) were surveyed about drug use. Questions were included to assess their perceived likelihood of recent media coverage about medical benefits associated with use of ketamine and MDMA affecting their own use. Results: Two-thirds (66.8%) of participants had ever used ecstasy/MDMA and 22.6% had ever used ketamine. The plurality of participants reported that media coverage about ketamine (46.1%) and MDMA (39.9%) did not affect their likelihood of using. 10.1% and 21.0% of participants reported increased likelihood of using ketamine and MDMA, respectively. 52.3% of those reporting past-month ketamine use and 6.1% of those reporting no lifetime use reported being more likely to use in response to media coverage about ketamine. 28.6% of those reporting past-month ecstasy use and 5.5% of those reporting no lifetime use reported being more likely to use in response to media coverage about MDMA. Discussion: Media coverage about the medical benefits of ketamine and MDMA might influence specific subsets of people to use.
RESUMO
BACKGROUND: The past decade has seen increasing attention directed to the development of HIV prevention interventions for male couples, driven by epidemiological data indicating that main or primary - rather than causal - partnerships account for a substantial number of HIV infections in this population. Couples HIV testing and counseling (CHTC) has emerged as a standard of care in the US. This protocol describes a study that aims to evaluate the efficacy of two adjunct components to CHTC - communication training (CT) videos and a substance use module (SUM) - to reduce drug use and sexual HIV transmission risk behavior. METHODS: Eligible couples must include one participant who is aged 17-29, HIV-negative, and reports recent drug use. Both partners must be aged 17 or older, identify as cismale (assigned male sex at birth and currently identify as male gender), and communicate in English. Couples are randomized post-baseline to one of four conditions (CHTC as usual, CHTC plus CT video; CHTC + SUM and CHTC + CT video + SUM) in a full-factorial design. Follow up assessments are completed at 3-, 6-, 9- and 12-months post baseline. DISCUSSION: Results of this trial will enhance the application of CHTC. If found effective, adjunct components would comprise a brief and scalable drug use intervention that could be readily integrated into existing HIV testing settings.

Researchers have established that substance use interferes with anti-retroviral medication adherence among gay and bisexual men (GBM) living with HIV. There is limited parallel examination of pre-exposure prophylaxis (PrEP) adherence among HIV-negative GBM. We conducted retrospective 30-day timeline follow-back interviews and prospective semi-weekly diary data for 10 weeks with 104 PrEP-using GBM, half of whom engaged in club drug use (ketamine, ecstasy, GHB, cocaine, or methamphetamine)-generating 9532 days of data. Participants reported their day-by-day PrEP, club drug, marijuana, and heavy alcohol use (5 + drinks in one sitting). On average, club drug users were no more likely to miss a dose of PrEP than non-club drug users (M = 1.6 doses, SD = 3.0, past 30 days). However, we found that club drug use (at the event level) increased the odds of missing a dose on the same day by 55% and the next day (e.g., a "carryover effect") by 60%. Further, missing a dose on one day increased the odds of missing a dose the following day by eightfold. We did not identify an event-level effect of marijuana use or heavy drinking on PrEP adherence. Our data suggest club drug users could have greater protective effects from daily oral or long-acting injectable PrEP compared to a time-driven PrEP regimen because of the concurrence of club drug use and PrEP non-adherence.

AIMS: There is increased concern about the use of alcohol and illicit drugs in nightlife settings. Most studies of substance use in nightlife settings are from the patrons' perspective, which leaves an understudied population - the nightclub staff. The aim of this paper is to study self-reported alcohol and substance use among staff at licensed premises in Norway: types of illicit drugs used, attitudes towards drugs, and observed drug use among patrons. METHODS: A survey was conducted at server-training courses in 20 different cities in Norway during 2015. The survey included: demographics, respondents' own alcohol and drug experience, attitudes towards drug use, and observed drug use among patrons at licensed premises. RESULTS: Data were collected from 912 staff working at licensed premises. A majority reported alcohol use in the past year, and 61% reported alcohol use two or more times a month. Overall, 45% of the respondents reported ever-used of illicit drugs. The four most commonly used drugs among staff were cannabis, cocaine, ecstasy/MDMA, and amphetamine. The majority of respondents supported Norway's strict drug laws, and 63% reported observing drug-intoxicated patrons at licensed premises during the past six months. CONCLUSIONS: The proportion of frequent drinkers and heavy episodic drinking among staff at licensed premises was high, and the prevalence of illicit drug use was much higher compared with the general population. Thus, staff at licensed premises can be considered a risk-group for alcohol and illicit drug use and therefore represent an important target population in club drug-prevention programmes.

Young women who regularly attend nightclubs are at risk for numerous health and social consequences, including mental distress, sexual and physical victimization and substance dependence. This paper uses a biopsychosocial framework to examine co-occurring mental health problems, victimization, substance dependence, sexual risk and physical pain among a sample of young women who use drugs (N = 222) in Miami's club scene. The majority of women were under 24 years old, Hispanic, and identified as heterosexual. Almost all the women reported past 90-day use of alcohol, ecstasy/MDMA, marijuana, cocaine and prescription opioids and benzodiazepines; 32% of women reported being in a monogamous relationship while 41.9% reported having three or more sexual partners in the past 90 days; 65.3% met DSM-IV criteria for substance dependence; 60.4% met DSM-IV criteria for serious mental illness (SMI) and 59.9% were victimized as minors. Women who had SMI had higher odds of substance dependence, concurrent physical pain, three or more sexual partners in the past 90 days, childhood victimization and severe abuse-related trauma. The high levels of interconnected mental health, victimization, trauma, physical pain, substance dependence and sexual risk factors observed are underreported in the literature, as young women club scene participants appear to be more similar to other marginalized drug-involved populations than previously considered. While further research is needed, it appears these young women are in great need of outreach for primary health, mental health, HIV prevention, increased social support and substance abuse treatment services.

This study examines the association between proximity of place of residence to preferred nightclub and substance use, sexual risk behaviors, and related problems, among a sample of 498 young adult substance users in Miami who report regular nightclub participation. Hierarchal linear models and logistic regressions were constructed to examine the impact of residential proximity to preferred nightclub on risk behaviors. Compared with participants residing in closer proximity to their preferred nightclub, participants residing further away reported higher intensities of alcohol and cocaine use (p < .01), greater condomless vaginal sex frequencies (p < .001), and more substance dependence symptoms (p < .05). Conversely, participants residing in closer proximity to their preferred nightclub had higher likelihood of arrest history (p < .05) than participants residing further away. Results suggest that participants residing further from their preferred nightclubs may be more invested in the nightclub outing and, therefore, engage in more risk behaviors.
RESUMO
Club drugs and alcohol abuse are prevalent among methadone maintenance treatment (MMT) patients. However, little is known about the association between these abuse and treatment outcomes among MMT patients. The aim of this study was to examine the prevalence of club drugs and alcohol abuse among MMT patients and to investigate the associations between these abuse and treatment outcomes - dropout and poor adherence. In this one-year cohort study conducting in Guangzhou, China, data including background characteristics, club drugs use in the last six months, alcohol use history and treatment-related information was collected. Cox regression analyses and log-binomial regression analyses were applied to identify the associations between these abuse and dropout and poor adherence, respectively. Thirty-seven participants (9.2%) admitted to the use of at least one type of club drugs in the last six months and 88 (21.9%) were identified as alcohol abusers. Of all participants, 21.0% had dropped out of treatment and 27.7% exhibited poor adherence during the study period. Adjusting for significant background variables, use of at least one type of club drugs [hazards ratio (HR) = 1.90, 95% confidence interval (CI) = 1.01-3.56] and use of methamphetamine in the last six months (HR = 2.26, 95% CI = 1.15-4.43) significantly predicted dropout. Frequency of having six or more drinks on one drinking occasion when drinking [relative risk (RR) = 1.87, 95% CI = 1.16-2.95] significantly predicted poor adherence. Our findings indicated that club drugs and alcohol abuse predicted dropout and poor adherence among MMT patients. Early identification and intervention for the abuse should be taken into consideration when developing interventions tailored to improve treatment outcomes among MMT patients.

BACKGROUND: The affinity for substance use among patrons of nightclubs has been well established. With novel psychoactive substances (NPS) quickly emerging on the European drug market, trends, and patterns of use are potentially changing. OBJECTIVES: (1) The detection of subgroups of consumers in the electronic dance music scene of a major German metropolitan city, (2) describing the consumption patterns of these subgroups, (3) exploring the prevalence and type of NPS consumption in this population at nightlife events in Munich. METHODS: A total of 1571 patrons answered questions regarding their own substance use and the emergence of NPS as well as their experience with these substances. A latent class analysis was employed to detect consumption patterns within the sample. RESULTS: A four class model was determined reflecting different consumption patterns: the conservative class (34.9%) whose substance was limited to cannabis; the traditional class (36.6%) which especially consumed traditional club drugs; the psychedelic class (17.5%) which, in addition to traditional club drugs also consumed psychedelic drugs; and an unselective class (10.9%) which displayed the greatest likelihood of consumption of all assessed drugs. "Smoking mixtures" and methylone were the new substances mentioned most often, the number of substances mentioned differed between latent classes. CONCLUSION: Specific strategies are needed to reduce harm in those displaying the riskiest substance use. Although NPS use is still a fringe phenomenon its prevalence is greater in this subpopulation than in the general population, especially among users in the high-risk unselective class.

AIMS: Alcohol and illicit substance use among young adults carries the risk of adverse consequences like violence, injuries, risky sexual behaviour and, ultimately, the development of possible addiction. The nightlife arena is a high-risk setting for excessive substance use and the aims of this study were to examine prevalence rates and identify high-risk subgroups in this context. METHODS: Patrons ( n = 1099, response rate 76%) entering or exiting 12 popular licensed premises in downtown Oslo, Norway, completed an anonymous self-administered questionnaire and their blood alcohol concentration (BAC) levels were measured using a Breathalyzer. RESULTS: The average BAC levels were similar ( t = 1.67, degrees of freedom (df)= 936, non-significant (ns)) and high both for males (1.03) and females (0.97). A total of 67% reported ever using illicit drugs, 43% reported last-year use, 25% last-month use and 14% use during the last 48 hours. High-risk groups included the youngest patrons (16-20 years) where 50% reported illicit drug use in the last year. Males reported more use of illicit drugs than females, whereas females had equally high alcohol consumption frequency and intoxication levels as males. Young age, male gender, frequent alcohol intoxications and age < 15 for first alcohol intoxication experience were associated with increased risk of illegal substance use in multivariate analyses. CONCLUSIONS: The high levels of alcohol and illicit drug use, particularly among patrons younger than 21 years, should be of concern to the community, policymakers and the nightlife industry. The nightlife arena may be an under-utilized setting for the implementation of risk-reducing interventions.
RESUMO
BACKGROUND: Men who have sex with men (MSM) are a risk group for new HIV infections. Drug use among men who have sex with men is often accompanied by risky sexual behaviours. Local AIDS help centres and gay advice centres are recording an increase in drug use among MSM clients in Germany. This study examines reasons for drug use and drug use contexts for MSM, including syndemic factors and experiences of social support. METHODS: The study is based on a qualitative research approach. We conducted 14 structured, in-depth interviews with substance-using MSM in three German cities. An interview guidance document was used that was developed on the basis of the syndemic approach. Data analysis was based on structured analysis of content. RESULTS: The MSM interviewed had extensive experience of drug use, in particular amyl nitrate, amphetamines, methamphetamine, ketamine, cocaine and cannabis. The drugs were used both at parties and in connection with sexual experiences (chemsex). Twelve men said that they had an existing HIV infection at the time of the interview. The men also reported experiences of violence and discrimination because of their sexual orientation. The social networks of the MSM and dating apps are highly relevant for experiencing chemsex. Certain places in the MSM community also have an impact on drug purchase, drug consumption and chemsex sessions. CONCLUSIONS: MSM are a group that is vulnerable to psychological problems, in particular problematic drug use. This group requires specific help from drug services and AIDS support services that are orientated towards the life situation and substance use contexts of the clients. Both support systems should work together more closely and network. Furthermore, specific prevention strategies, aimed at both mental and physical well-being, should be developed for substance-using MSM.

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.

BACKGROUND: Couples HIV testing and counseling (CHTC) is now a standard of care prevention strategy recommended by the Centers for Disease Control and Prevention for sexual minority men (SMM) in relationships. Despite standard recommendations that couples complete CHTC every 6-12 months, no study has empirically evaluated the effects associated with CHTC retesting. OBJECTIVE: This study aims to understand the benefits associated with continued dyadic engagement in the HIV prevention continuum through routine CHTC retesting, which is of particular importance for emerging-adult SMM in relationships who use drugs. METHODS: Eligible couples for this CHTC retesting trial must already be enrolled in the 4Us trial, where they completed a CHTC session after their baseline survey. The purpose of the original 4Us trial was to test the efficacy of 2 intervention components for CHTC: a communication skills training video and a substance use module. Couples were eligible for the original 4Us trial if they identified as cisgender male, were in a relationship for 3 months or longer, were aged 17 years or older, and communicated in English. At least 1 partner had to be aged 17-29 years, report HIV negative or unknown serostatus, report use of at least 1 drug (cannabis, cocaine or crack, crystal methamphetamine, ketamine, gamma-hydroxybuterate [GHB], psychedelics, ecstasy, prescription medication misuse, opiates, and nitrates) use, and engage in condomless anal sex (CAS) acts with a casual partner or have a main partner who is nonmonogamous or serodiscordant. Those who complete the 4Us 12-month follow-up and remain in a relationship with the partner they participated in 4Us with are offered the opportunity to participate in this CHTC retesting trial. Those consenting are randomized to either CHTC retesting or individual HIV testing. Follow-up assessments are conducted 3 and 6 months after randomization to evaluate the effects of repeat CHTC on 2 primary outcomes: (1) CAS with a casual partner in the absence of preexposure prophylaxis (PrEP), and (2) CAS with a serodiscordant main partner who is not virally suppressed or concurrent CAS between main and casual partners in the absence of PrEP. RESULTS: The CHTC retesting trial launched in January 2023, and enrollment is ongoing. As of February 2024, the study had enrolled 106 eligible participants (n=53 couples). CONCLUSIONS: Findings from this CHTC retesting study will contribute to knowledge about the benefits associated with regular (repeated) CHTC testing versus routine individual HIV testing for SMM in relationships. The results of this trial will inform CHTC retesting guidance. TRIAL REGISTRATION: ClinicalTrials.gov NCT05833074; htps://www.clinicaltrials.gov/study/NCT05833074.

RESUMO
Gamma-hydroxybutyrate (GHB) was a somewhat prevalent club drug two decades ago, but research has been lacking regarding the current epidemiology of use. In this study, prevalence and correlates of past-year GHB use were estimated based on noninstitutionalized US adults participating in the 2015-2020 National Survey of Drug Use and Health (N= 241,675). An estimated 0.05% (95% CI: 0.04-0.07) of adults in the US have used GHB in the past year. Compared to those age 18-25, those age 35-49 were at increased odds for use (aOR = 2.28, 95% CI: 1.02-5.10), and compared to heterosexual men, gay men in particular were at high odds for use (aOR = 27.82, 95% CI: 11.09-69.80). Those identifying as bisexual men (aOR = 3.39, 95% CI: 1.17-9.82) and lesbian/bisexual women (aOR = 3.37, 95% CI: 1.44-7.90) were also at high odds for use. Despite all drugs examined being significant correlates of use in bivariable models (ps < .001), only past-year use of methamphetamine (aOR = 15.68, 95% CI: 7.40-33.25), ketamine (aOR = 8.52, 95% CI: 2.67-27.20), and ecstasy (aOR = 4.41, 95% CI: 1.80-10.75) was associated with increased odds of use in the multivariable model. Results suggest that GHB use is currently rare, but gay men and people who use other party drugs are at particularly high risk for use.
RESUMO
Few epidemiological studies have focused on seasonal variation in the use of common psychedelics and party drugs among nightclub and festival attendees, typically those who attend electronic dance music (EDM) events. We sought to determine whether the use of different drug types varies seasonally within this population. Across 15 seasons from summer 2017 through fall 2022, we surveyed 3,935 adults entering randomly selected nightclubs and festivals in New York City regarding their past-month use of cocaine, MDMA (3,4-methylenedioxymethamphetamine, commonly known as ecstasy), lysergic acid diethylamide (LSD), psilocybin (shrooms), and ketamine. Multivariable models were used to compare adjusted odds ratios for drug use within each season with the grand mean of combined seasons. Summer was associated with higher odds for use of LSD (aOR 2.72; 95% CI, 1.88-3.93) and psilocybin (aOR 1.65; CI, 1.12-2.43), independent of increases in psilocybin use over time (p < .001). A significant increase in use of ketamine (p = .014) and significant decreases in use of cocaine (p = .002) and ecstasy (p = .002) were found across time, but multivariable models did not detect seasonal variations. Summer is a risk factor for use of common psychedelics among people who attend EDM events. Therefore, the summer months may be the best time to disseminate information about harm reduction for psychedelic drug users.
RESUMO
INTRODUCTION: People who attend nightclubs and festivals are known for high prevalence of party drug use, but more research is needed on underreporting in this population, in part because unintentional drug exposure through adulterated drug products is common. We examined the prevalence of drug use in this population, based both on self-reporting and on hair test results, with a focus on the detection of underreported use. METHODS: Adults entering nightclubs and festivals in New York City were asked about past-year drug use in 2019-2022 (n = 1,953), with 328 providing an analyzable hair sample for testing. We compared trends in self-reported drug use, drug positivity, and "corrected" prevalence, adjusting for unreported use, and delineated correlates of testing positive for ketamine and cocaine after not reporting use (discordant reporting). RESULTS: Of the 328 who provided a sample, cocaine and ketamine were the most frequently detected drugs (55.2% [n = 181] and 37.2% [n = 122], respectively), but these were also the two most underreported drugs, with 37.1% (n = 65) and 26.4% (n = 65), respectively, testing positive after not reporting use. Between 2019 and 2022, positivity decreased for cocaine, ketamine, 3,4-methylenedioxy-metamfetamine, and amfetamine, and underreported exposure to cocaine and ketamine also decreased (P < 0.05). Underreporting of the use of these drugs was common, but we also detected underreported exposure to ethylone, fentanyl, 3,4-methylenedioxyamfetamine, metamfetamine, and synthetic cannabinoids. Prevalence of discordant reporting of cocaine use was higher among those testing positive for ketamine exposure (adjusted prevalence ratio = 2.63; 95% CI: 1.48-4.69) and prevalence of discordant reporting of ketamine use was lower post-coronavirus disease caused by the SARS-CoV-2 virus (adjusted prevalence ratio = 0.39; 95% CI: 0.16-0.91) and among those reporting cocaine use (adjusted prevalence ratio = 0.53; 95% CI: 0.32-0.89). DISCUSSION: Underreporting of drug use was common, suggesting the need for researchers to better deduce intentional underreporting versus unknown drug exposure via adulterants. CONCLUSIONS: Researchers should consider both self-report and toxicology results from biological samples when examining trends in use.
