Poisoning by psychoactive substances is increasingly common in Europe and can be responsible for deaths. These substances, also called "festive drugs", circulate among other places in festive gatherings (night clubs, concerts, free music, feria, etc.). The main objective of this study is to determine the molecules that circulate in festive events in Aquitaine, in order to implement prevention actions by looking at whether the circulating substances vary with the style of event.

Poisoning by psychoactive substances is increasingly common in Europe and can be responsible for deaths. These substances, also called "festive drugs", circulate among other places in festive gatherings (night clubs, concerts, free music, feria, etc.).

There is also a significant increase in the number of new psychoactive substances (NSPs) whose toxicity is unknown: by 2014, 101 new substances were detected for the first time in Europe. These molecules, because of this regular and rapid emergence, are not included in the narcotics list, in the great majority of cases.

Poison control centers, as well as addictovigilance centers, are regularly called upon for serious poisoning resulting in hospitalization, for which analytical evidence is most often missing or difficult to obtain. The lack of documentation, both analytical and clinical, of these files limits its expertise. As a result, medical knowledge, in particular clinical knowledge, progresses little which limits the efficiency of the management of these poisonings.

A 2015 pilot study on the Dax and Mont-de-Marsan (FERIATOX) fertilization sites on 27 patients showed that although several psychoactive substances have been identified in these patients (cocaine, ketamine, MDMA, cannabis, etc.) No DK was identified in this study. It is possible, however, that the profile of people who frequent ferias is different from that of music festivals, which explains the lack of identification of these substances in the FERIATOX study. To support this hypothesis, it seems important to renew this study on festive events of the type of music festival. The Garorock Festival (Marmande), held at the beginning of July, seems to be relevant for the study.
