Abstract

Objective: new psychoactive substance use (NPS) is a reality in France, including among drivers. This work aims (i) to report pharmaceutical design of NPS detected in oral fluid (OF) from drivers initially screened for drugs around a music festival in 2019, and (ii) to compare obtained results with those of a previous similar study carried out in 2017 in the same situation (and the same music festival) and according to the same methodology. Methods: OF specimens were recovered from the used devices of the salivary immunochemical tests used by the police during the controls carried out at the entering and leaving the festival. These OF were analyzed using a liquid chromatography coupled with tandem mass spectrometry and high-resolution mass spectrometry methods using mass spectra libraries of approximately 1700 substances including (in 2020) more than 650 NPS and metabolites. Results: NPS were detected in 14 out of the 265 collected OF specimens. Ten NPS were identified (number of identification): APINACA (1), AB-Chminaca (1), 5F-AMB (1), 5F-PB-22 (5), 2C-D (1), methoxetamine (2), ketamine (1), x-CMC (1), 4-MEC (2), ethylone (2). The prevalence of NPS detection in OF (5.2%) is in the same order than the observed one in 2017 (6.8%) but these results are marked by the majority and increasing proportion of synthetic cannabinoids (47% of identified NPS in 2019 vs 25% in 2017), an increase also in the proportion of cathinone derivatives (29% in 2019 vs 6 % in 2017), and a decrease in cyclohexanones (17% in 2019 vs 43% in 2017). Conclusion: these pharmaceutical design trends (2019 vs 2017) observed in a population of drivers around a music festival seem to reflect those that can be seen in more general populations in France, with probably a rise in the consumption of synthetic cannabinoids.
