Illicit drugs consumption can be back-calculated based on the analysis of drug residues in wastewater using the wastewater-based epidemiology method. The Music Day, held on June 21 in France since 1982, has grown to global proportions and is now celebrated as World Music Day. This large outdoor event takes place in many cities with people allowed to play music in the streets. As psychotropic drugs are often associated with music events, the goal of this study is to investigate the use of illicit drugs on this day in Bordeaux, the fifth largest urban area in France. Daily sampling campaigns of composite wastewater were carried out for seven days in two wastewater treatment plants in Bordeaux in 2017 (Music Day) and 2018. World Music Day in Bordeaux has no observable effect on illicit drug consumption even if this event has massive public participation: this is the first report of the absence of an illicit drug consumption increase in a festival of such magnitude, corroborating the effect of others' views and opinions, because this event takes place publicly in the street and not among peers. Different hypothesizes are put forward to explain this fact: inappropriate type of event for drug consumption, effect of other festivals, and influence of the event's timing on a weekday.
非法药物的使用量可通过基于废水分析的药物残留的废水流行病学方法进行回溯推算。自 1982 年以来，法国将 6 月 21 日设立为音乐节，该节日已经发展成为全球性节日，现被称为世界音乐日。这个大型户外活动在许多城市举行，人们可以在街头演奏音乐。由于精神药物通常与音乐活动有关，因此本研究的目的是调查 2017 年（音乐节）和 2018 年在法国第五大城市波尔多的两个污水处理厂进行的为期七天的综合废水每日抽样活动中非法药物的使用情况。即使该活动有大量公众参与，波尔多的世界音乐日对非法药物的使用量并没有明显的影响：这是首次在如此大规模的节日中报告没有非法药物使用量增加的情况，证实了他人观点和意见的影响，因为该活动是在公共街道上公开举行的，而不是在同龄人中举行的。提出了不同的假设来解释这一事实：不适合药物消费的活动类型、其他节日的影响以及活动时间安排在工作日的影响。
