RATIONALE/BACKGROUND:Current prevalence estimates of synthetic cathinone ("bath salt") use may be underestimates given that traditional metrics (e.g., surveys, urinalysis) often fail to capture the emergent issue of synthetic cathinone adulteration of more common illegal drugs, such as ecstasy (3,4-methylenedioxymethamphetamine). OBJECTIVES/OBJECTIVE:This review examines the evolution of synthetic cathinones and prevalence of use over the past decade in the United States. We also review methods of self-report and biological testing of these compounds as well as adverse outcomes associated with adulterated drug use. RESULTS:Synthetic cathinone use emerged in the United States by 2009 with use associated with tens of thousands of poisonings. Reported poisonings and self-reported use have substantially decreased over the past five years. However, our review suggests that current estimates of use are underestimates due to underreporting stemming primarily from unknown or unintentional use of adulterated formulations of relatively popular illegal drugs, such as ecstasy. CONCLUSIONS:While intentional synthetic cathinone use has decreased in recent years, evidence suggests that prevalence of use is underestimated. Testing of drugs and/or biological specimens can improve the accuracy of synthetic cathinone use estimates. Furthermore, we advocate that researchers and clinicians should become better aware that exposure to these potent compounds (e.g., as adulterants) often occurs unknowingly or unintentionally. To improve our understanding of synthetic cathinone adulteration, research utilizing a combinatorial approach (survey and biological testing) will help more accurately estimate the prevalence and impact of this public health issue.

OBJECTIVE:To estimate prevalence of past-month marijuana, cocaine, and nonmedical prescription opioid (NPO) use and determine employment-related correlates of drug use among construction trade/extraction workers (CTEW). METHODS:We analyzed ten years of data (2005-2014) from 293,492 adults (age≥18) in the National Survey on Drug Use and Health, comparing CTEW and non-CTEW. RESULTS:CTEW were 5.6% (n = 16,610) of the sample. Compared to non-CTEW, CTEW were significantly more likely to report past-month marijuana (12.3% vs. 7.5%), cocaine (1.8% vs. 0.8%), and/or NPO use (3.4% vs. 2.0%; Ps<.001). Among CTEW, past-week unemployment and working for >3 employers was associated with increased odds of marijuana and NPO use. Missing 1-2 days in the past month because the participant did not want to go into work was associated with increased odds for use of marijuana, cocaine, and NPO use. Missing 3-5 days of work in the past month because sick or injured was associated with double the odds (aOR = 2.00 [95% CI: 1.33-3.02]) of using NPO. Having written drug policies was associated with reduced odds for cocaine use, and workplace tests for drug use during hiring and random drug testing were also associated with lower odds of marijuana use. CONCLUSIONS:CTEW are a high-risk population for drug use. Precarious employment is associated with higher prevalence of drug use while some workplace drug policies were associated with lower prevalence. Coupled with reports of high overdose mortality among CTEW, these findings suggest that prevention and harm reduction programming is needed to prevent drug-related morbidity and mortality among CTEW.

BACKGROUND:"Drug checking" has become a common harm reduction method used to test illicit substances, such as ecstasy, for purity and/or the presence of adulterants. Formal drug-checking services have been operating for decades, and the use of personal reagent test kits appears to be relatively common; however, little attention has been devoted to understanding the role and broader experiences of 'drug-checkers' (i.e., people who test their own and/or other people's substances). As such, it remains unknown who is engaging in this practice, their motivations for drug-checking, and what barriers they may experience. We addressed this research gap by interviewing people who check drugs about their experiences, with a goal of better understanding drug checking practices. METHODS:We conducted in-depth interviews with 32 adults in North America who reported testing drugs. Coding was conducted in an inductive manner and thematic analysis was used to identify relevant themes. RESULTS:Over half (56.2%) of our sample was affiliated with a drug checking organization. Among non-affiliated checkers (43.8%), the majority (57.1%) tested for friends, 21.4% tested only for themselves, and 21.4% were people who sold drugs and tested for their clients. Motivations were driven largely by altruism, described by checkers as wanting to protect their peers from exposure to adulterants. People interviewed who sold drugs were altruistic in the same manner. Barriers to checking-particularly at nightclubs and festivals-included perceived illegality of test kits and denied approval to test drugs at venues, although many checkers circumvented this barrier by checking drugs without such approval. CONCLUSIONS:Drug checkers in North America seek to educate people who use drugs about the risk of exposure to unexpected substance types, but they face various barriers. Policy change could help ensure that these potentially life-saving services can be provided without fear of fines and/or criminal prosecution.

Background/UNASSIGNED:The ceremonial use of psychoactive/hallucinogenic plant based drugs, such as ayahuasca, psilocybin and others, is a growing trend in the United States (US) and globally. To date, there has been little research documenting how many people are using psychoactive substances in this context, who the users are, what benefits/risks exist in the use of these drugs and the relationship between ceremonial drug use and recreational drug use.In this paper we describe a cohort of plant medicine facilitators in the US and explore how they differentiate plant medicine use from recreational drug use. Methods/UNASSIGNED:Using modified ethnography, individual interviews were conducted in 2016 with 15 participants who are currently facilitating plant medicine ceremonies in the US. Descriptive content analysis was performed to discover themes and to inform a larger mixed-method study. Results/UNASSIGNED:Ceremonial drug use was seen by participants as a natural healing and treatment modality used in the context of community and ritual. Three main themes were identified relating to participants' differentiation between ceremonial plant medicine use and recreational drug use: 1) participants see a clear delineation between plant medicine use and recreational drug use; 2) plant medicine is seen as a potential treatment for addiction, but concerns exist regarding potential interference with recovery; and 3) plant medicine use may influence recreational use. Conclusions/UNASSIGNED:More research is needed on who is using plant medicine, motivators for use, perceived and real risks and benefits of plant medicine use and harm reduction techniques regarding safe ingestion.

Background: Drug use among electronic dance music (EDM) party attendees is common; however, studies are needed to examine associations between drug use and sexual orientation as this can inform prevention and harm reduction efforts in the lesbian, gay, and bisexual (LGB) community. Methods: Data were examined from a repeated cross-sectional study of 3066 young adult EDM party attendees surveyed entering nightclubs and dance festivals in New York City between 2016 and 2018. Of these participants, 277 identified as gay/lesbian, 293 identified as bisexual, and 83 identified as other sexuality. We examined how sexual orientation relates to past-year use of various 'traditional' drugs (e.g., ecstasy/MDMA/Molly) and new psychoactive substances (NPS; e.g., "bath salts") in a bivariable and multivariable manner, stratified by sex. Results: Compared to heterosexual males, gay males were at higher odds for use of ecstasy, GHB, and methamphetamine; bisexual males were at higher odds for use of LSD and unknown powders, and males identifying as "other" sexuality were at higher odds for use of mushrooms and 2C drugs. Compared to heterosexual females, lesbians were at higher odds for use of mushrooms and GHB; bisexual females were at higher odds for use of cocaine, LSD, mushrooms, and tryptamines, and females identifying as "other" sexuality were at higher odds for use of cocaine and tryptamines. Conclusions: We determined differential risk of use of different drugs among those who attend EDM parties according to sexual orientation. Findings can be used to tailor prevention messaging to specific groups within the LGB community.

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.

Background: Posting on social media can have lasting consequences in one's social life and career. Research has not yet focused on social media or more modern forms of communication as social risk factors for individuals high on drugs. This study aims to examine prevalence and correlates of engaging in social media posting and related behavior while high. Methods: We examined data from 872 adults (39.8% female) who were surveyed entering electronic dance music (EDM) parties in New York City and reported lifetime illegal drug use. Participants were asked whether they were ever high on a drug while (1) posting on social media, (2) calling or texting someone, and (3) being in a photo. Those answering affirmatively were also asked whether they later regretted the behavior. We examined demographic and drug-related correlates of these behaviors. Results: Of the participants, 34.3% posted on social media while high (with 21.4% regretting it), 55.9% had texted or called someone while high (with 30.5% regretting it), and 47.6% had been in a photo while high (with 32.7% regretting it). Females and young adults (ages 18-24) were at high risk for posting on social media while high and at higher risk for engaging in more of these behaviors. Past-month marijuana users in particular were at increased risk for engaging in each of these behaviors. Conclusion: Engaging in these behaviors while high on drugs appears to be prevalent, and prevention and harm reduction efforts should seek to prevent or reduce likelihood of social harm that can result from such situations.

OBJECTIVES/OBJECTIVE:Binge drinking is a risk factor for a range of harms. This study estimates the national prevalence of binge drinking and adds to our understanding of correlates of binge drinking among older adults in the United States. DESIGN/METHODS:Cross-sectional analysis. SETTING/PARTICIPANTS/METHODS:A total of 10 927 adults, aged 65 years or older, from the 2015 to 2017 administrations of the US National Survey on Drug Use and Health. MEASUREMENTS/METHODS:tests. We then used multivariable generalized linear models using Poisson and log link to examine the association between covariates and binge drinking among all past-month alcohol users aged 65 years or older. RESULTS:Of 10 927 respondents, 10.6% (95% CI = 9.9%-11.2%) were estimated to be current binge drinkers. Binge drinkers were more likely to be male, have a higher prevalence of current tobacco and/or cannabis use, and have a lower prevalence of two or more chronic diseases compared to nonbinge drinkers. In multivariable analysis, among past-month alcohol users, the prevalence of binge drinking was higher among non-Hispanic African Americans than whites (adjusted prevalence ratio [aPR] = 1.44; 95% CI = 1.16-1.80), tobacco users (aPR = 1.52; 95% CI = 1.33-1.74), cannabis users (aPR = 1.41; 95% CI = 1.11-1.80), and those who visited the ED in the past year (aPR = 1.16; 95% CI = 1.00-1.33). CONCLUSION/CONCLUSIONS:Over a tenth of older adults in the United States are estimated to be current binge drinkers. Results confirm the importance of screening for binge drinking behaviors among older adults to minimize harms.
