Harm Reduct J. 2023 Mar 29;20(1):43. doi: 10.1186/s12954-023-00770-5.
Illicit substance use has constantly evolved over the years, particularly in the party scene. Monitoring these changes is essential to adapt harm reduction strategies. The OCTOPUS survey was implemented to enhance knowledge on drug use at music festivals. The objective of the work presented here was to describe drug use and to characterize profiles of substance use in music festival attendees.
OCTOPUS was a cross-sectional survey carried out during 13 various music festivals (dub, eclectic and electronic music) in the Loire-Atlantique department (France) from July 2017 to July 2018. Participants were festival attendees. Data were collected by trained research staff using a face-to-face structured interview. We analysed the use of illicit drugs in the last 12 months to describe the prevalence of use and to characterize the profile of substance use using a latent class analysis.
In total, 383 festival attendees were included. Of 314 (82%) participants who reported drug use, the most reported drugs were cannabis, ecstasy/MDMA and cocaine. We identified two profiles of drug use: (i) a "no/low polysubstance use" profile mainly characterized by the use of "classic" stimulants (ecstasy/MDMA, cocaine) and (ii) "moderate/extensive polysubstance use", with high probabilities of "classic" stimulants use and especially other drugs reported: speed, ketamine, new psychoactive substances (NPSs).
We observed frequent polysubstance use in festival attendees. Harm reduction should be targeted at the increased risk of toxicity linked to polysubstance use, and the reduction in harm caused by particular drugs (ketamine, NPS, speed) could be further strengthened.
非法物质的使用多年来一直在不断演变，尤其是在派对场景中。监测这些变化对于适应减少伤害策略至关重要。实施 OCTOPUS 调查是为了增强对音乐节上药物使用的了解。本研究的目的是描述药物使用情况，并描述音乐节参与者的物质使用特征。
OCTOPUS 是一项横断面调查，于 2017 年 7 月至 2018 年 7 月在法国卢瓦尔河地区的 13 个不同音乐节（雷鬼、折衷和电子音乐）期间进行。参与者为音乐节参与者。数据由经过培训的研究人员使用面对面的结构化访谈收集。我们分析了过去 12 个月内非法药物的使用情况，以描述使用的普遍性，并使用潜在类别分析来描述物质使用特征。
共有 383 名音乐节参与者被纳入。在报告药物使用的 314 名（82%）参与者中，报告最多的药物是大麻、摇头丸/MDMA 和可卡因。我们确定了两种药物使用特征：（i）“无/低多药使用”特征，主要表现为“经典”兴奋剂（摇头丸/MDMA、可卡因）的使用；（ii）“中度/广泛多药使用”，“经典”兴奋剂使用的可能性较高，尤其是其他报告的药物：安非他命、氯胺酮、新精神活性物质（NPS）。
我们观察到音乐节参与者中频繁的多药使用。减少伤害应该针对与多药使用相关的毒性风险增加，并且可以进一步加强减少特定药物（氯胺酮、NPS、安非他命）造成的伤害。
