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.
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.
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).
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.
电子舞曲（EDM）派对参与者是药物使用和相关不良后果的高风险人群。我们研究了该人群中过去一年药物使用的趋势，以便更好地为预防和减少伤害工作提供信息。
每年夏天，从 2016 年到 2019 年，我们使用时空抽样法，在纽约市随机挑选的夜总会和舞蹈节上，对进入 EDM 派对的成年人进行了横断面调查。2019 年的 Ns 为 504，2016 年为 1087。我们估计了过去一年中 16 种不同的合成毒品或毒品类别的使用情况的对数线性趋势。
在 2016 年至 2019 年期间，估计过去一年使用氯胺酮的比例从 5.9%增加到 15.3%（相对增加 157.6%，P=0.007），使用 LSD 的比例从 9.9%增加到 16.6%（相对增加 67.7%，P<0.001），使用可卡因粉末的比例从 17.3%增加到 35.2%（相对增加 103.5%，P<0.001），使用 GHB 的比例从 1.0%增加到 4.2%（相对增加 311.8%，P=0.002）。过去一年使用>3 种药物的比例从 12.7%增加到 20.5%（相对增加 61.4%，P=0.013）；然而，估计过去一年使用未知粉末的比例从 2.0%下降到 1.1%（相对减少 44.7%，P=0.038），摇头丸/ MDMA / Molly 的使用在几年内保持稳定（在 25.0 到 28.5%之间；P=0.687）。
在 EDM 派对参与者中，可卡因粉末、LSD、氯胺酮和 GHB 的报告越来越普遍。需要采取预防和减少伤害的措施来应对使用的增加。还需要研究是否增加关于氯胺酮和其他迷幻药物的医学用途的媒体报道会影响娱乐性使用的流行率。
