Non-consensual sexual contact in bars is common, but few studies have focused on the extent of this problem at electronic dance music (EDM) parties, which are growing in popularity. We aimed to estimate prevalence and correlates of non-consensual sexual contact among individuals who attend EDM parties in New York City (NYC). Adults (ages 18-40 years) entering EDM parties in NYC were surveyed in 2018 using time-space sampling. Participants (n = 1005) were asked whether they had experienced unwanted or uninvited sexual contact including unwanted groping, kissing, or touching at an EDM party. We estimate that 15.2% of EDM party attendees in NYC have experienced non-consensual sexual contact at such parties. The majority (62.5%) of those reported that it occurred 1-2 times and 49.1% were usually or always drunk or high during the encounter(s). Almost all women experiencing non-consensual contact (99.5%) were all or mostly touched by men; 38.6% of men were all or mostly touched by other men. Women were at more than twice the odds of reporting non-consensual sexual contact than men (aOR = 2.38, p < .05) with 21.8% of women reporting experiencing non-consensual sexual contact compared to 11.0% of men. Among women, those ages 18-24 were at over twice the odds (aOR = 2.75, p < .05) of experiencing non-consensual sexual contact than those ages 25-40. EDM party environments can increase susceptibility to non-consensual sexual contact. Prevention needs to be geared toward those at risk, and education is needed for those likely to commit non-consensual sexual contact.

Background: Research has shown that lesbian, gay, and bisexual (LGB) young adults have substantially higher rates of tobacco, alcohol, and drug use compared to heterosexuals. Many have attributed these higher rates to minority stressors including discrimination and stigma. Substance use behaviors often continue through later life and can interact with chronic medical disease to increase the risk for adverse events. However, little research focuses on the prevalence of unhealthy substance use among older LGB adults. This study estimates the national prevalence of substance use among LGB middle-aged and older adults and odds of use relative to heterosexuals.
Method(s): We examined aggregated data from 25,880 adults age >=50 from the 2015 to 2017 National Survey on Drug Use and Health, an annual cross-sectional survey of a nationally representative sample of non-institutionalized individuals in the United States. We estimated the prevalence for past-month binge drinking and past-year non-medical cannabis use, alcohol use disorder, nicotine dependence, cocaine, methamphetamine, and prescription opioid, sedative, stimulant, and tranquilizer misuse and their odds of use relative to heterosexual adults age >=50 adjusting for age, gender, race, income, and marital status.
Result(s): In adjusted analyses, we found that LGB adults age >=50 were at 2.3 times higher odds (95% confidence interval [CI]=1.6, 3.2) of reporting past-year non-medical cannabis use; they were at 1.7 times higher odds (95% CI 1.1, 2.5) of reporting prescription opioid misuse, and 2.4 times higher odds (95% CI 1.3, 4.3) of reporting prescription tranquilizer misuse compared to heterosexuals. We did not find significant differences in use of other substances.
Conclusion(s): Consistent with other studies of younger LGB, this study shows some substance use is higher in older LGB adults compared to their heterosexual counterparts. LGB middle-aged and older adults are at higher risk for cannabis use, prescription misuse of opioids and tranquilizers. Prevention and interventions for unhealthy substance use should focus on older LGB populations to reduce harms.

OBJECTIVE:Electronic dance music (EDM) party attendees are a high-risk population for drug use and associated adverse effects. We examined trends in past-year drug use within this population to better inform prevention and harm reduction efforts. METHODS:Each summer from 2016 through 2019, we used time-space sampling to survey a cross-section of adults entering EDM parties at randomly selected nightclubs and at dance festivals in New York City. Ns ranged from 504 (2019) to 1,087 (2016). We estimated log-linear trends in past-year use of 16 different synthetic drugs or drug classes. RESULTS:Between 2016 and 2019, estimated past-year prevalence of use of ketamine increased from 5.9% to 15.3% (a 157.6% relative increase; P = .007), LSD use increased from 9.9% to 16.6% (a 67.7% relative increase, P < .001), powder cocaine use increased from 17.3% to 35.2% (a 103.5% relative increase, P < .001), and GHB use increased from 1.0% to 4.2% (a 311.8% relative increase; P = .002). Past-year use of >3 drugs increased from 12.7% to 20.5% (a 61.4% relative increase; P = .013); however, estimated past-year use of unknown powders decreased from 2.0% to 1.1% (a relative 44.7% decrease; P = .038) and ecstasy/MDMA/Molly use was stable across years (at 25.0 to 28.5 %; P = .687). CONCLUSIONS:Reports of powder cocaine, LSD, ketamine, and GHB are becoming more prevalent among EDM party attendees. Prevention and harm reduction efforts are needed to address increasing use. Research is also needed to examine whether increasing media coverage of medical use of ketamine and other psychedelics affects prevalence of recreational use.

OBJECTIVE:The number of novel psychedelic phenethylamines and tryptamines has continued to increase, but little academic research has focused on the effects of these substances. We sought to determine and compare the subjective effects of various substances. METHODS:We conducted in-depth interviews with 39 adults (75.4% male and 87.2% White) who reported experience using psychedelic phenethylamines and/or tryptamines. Participants described the effects of compounds they have used. We examined the subjective drug effects in a qualitative descriptive manner. RESULTS:Participants reported on the use of 36 compounds. The majority (64.1%) reported the use of 2C series drugs, with 2C-B use being most prevalent; 38.5% reported the use of NBOMe, and 25.6% reported the use of DOx. With regard to tryptamines, 46.2% reported use, and 4-AcO-DMT was the most prevalent drug used in this class. 2C-B was often described as being more favorable than other 2C series compounds with the effects described as being comparable with MDMA and LSD. NBOMe effects were generally described in an unfavorable manner, and the effects of DOx were often described as lasting too long (12-36 hr). The effects of 4-AcO-DMT were often described as mimicking psilocybin. CONCLUSION/CONCLUSIONS:Knowing the effects of various compounds can inform education, prevention, and harm reduction efforts regarding the use of these drugs.

Objectives/UNASSIGNED:Skip-logic is commonly used on electronic surveys in which programs provide follow-up questions to affirmative responses and skip to the next topic in response to non-affirmative responses. While skip-logic helps produce data without contradictory responses, erroneous non-affirmative reports can lead to loss of accurate information. We examined the extent to which type-in drug use responses contradict unreported use in a survey of a high-risk population-electronic dance music (EDM) party attendees. Design/UNASSIGNED:We surveyed 1029 EDM party-attending adults (ages 18-40) using time-spacing sampling in 2018. We examined the extent to which reporting of recent drug use via type-in responses occurred after past-year use of the same drugs were unreported earlier on the same survey. Changes in prevalence of use and predictors of providing discordant responses were examined. Results/UNASSIGNED:< .001) were at higher odds of providing a discordant response. Conclusions/UNASSIGNED:Electronic surveys that query drug use can benefit from follow-up (e.g. open-ended) questions not dependent on previous responses, as they may elicit affirmative responses underreported earlier in the survey.

Background/UNASSIGNED:Ecstasy (3,4-methylenedioxymethamphetamine [MDMA]), commonly referred to as Molly in the US, is commonly adulterated with drugs potentially more dangerous than MDMA. Synthetic cathinones ("bath salts") are common adulterants, and use of these compounds tends to be stigmatized. We investigated whether presenting information on the extent of ecstasy being adulterated with "bath salts" affects intentions to use. Methods/UNASSIGNED:A total of 1,025 adults entering electronic dance music parties were surveyed in 2018. Using an experimental posttest-only design with random assignment, half were randomly assigned to view a published Vice headline about ecstasy/Molly commonly being adulterated with "bath salts." Results/UNASSIGNED:= .030) of past-year ecstasy users' intention to test their ecstasy for adulterants. Conclusions/UNASSIGNED:Knowledge that ecstasy is commonly adulterated may help reduce the risk for future use among non-recent users and increase the willingness of users to test their ecstasy. This information can be used to target those at risk for ecstasy/Molly use.

Most human subjects research involving contact with participants has been halted in the US due to the COVID-19 crisis. We have been testing an online method to recruit and survey participants as a temporary replacement for our street-intercept survey method. Online surveys already generate less generalizable findings than other surveys, but offering compensation for online survey completion further reduces generalizability because this increases mischievous submissions. In this letter we discuss methods to help detect invalid responses, such as utilizing a screener to test for eligibility and using flags to detect mischievous responses and repeat submissions. We recommend that researchers approach online recruitment and surveying with caution.

INTRODUCTION AND AIMS/OBJECTIVE:Longitudinal studies have found that recanting of drug use is common. We investigate the extent to which individuals in a high-risk population-electronic dance music (EDM) party attendees-provide inconsistent reports of drug use. DESIGN AND METHODS/METHODS:Nine hundred and thirty-three EDM party attendees were intercept-surveyed before entering randomly selected parties in 2017. A quarter (n = 236) completed the optional follow-up survey (63.1% of those providing an email address to be contacted for follow up). We compared self-reported past-year drug use on baseline and follow-up surveys (mean = 3.6 days post-baseline) among those who completed both. Predictors for providing discordant responses were also examined. RESULTS:About 42.4% provided a discordant response between surveys, but discord regarding reported use of individual drugs (measured in changes in absolute percentage) ranged from 0.0% to 5.1%. At follow up, prevalence of reported use of LSD decreased (by 3.8%, P = 0.013) and prevalence of reported use of shrooms also decreased (by 5.1%, P = 0.005); however, test-retest reliability was strong or almost perfect for all 17 drugs (κ range: 0.88-1.00). Those reporting the use of a higher number of drugs at baseline were at increased risk of providing discordant responses. Those surveyed outside of festivals were less likely to provide more discordant responses than those surveyed outside of nightclubs. DISCUSSION AND CONCLUSIONS/CONCLUSIONS:Although reporting of drug use was very reliable in this high-risk population, inconsistent self-reported use of some drugs was still common. Research is needed to determine how to acquire more accurate responses in this population at the point of recruitment without relying on follow-up surveys.
