Prevalence of new psychoactive substances (NPS) in Brazil based on oral fluid analysis of samples collected at electronic music festivals and parties
In a study recently published in Drug and Alcohol Dependence, researchers examined the prevalence of new psychoactive substances (NPS) in Brazil through the analysis of oral fluid samples collected at parties and electronic music festivals. From 2018 to 2020, 462 oral fluid samples were collected from eleven parties and two festivals and analyzed with liquid chromatography–tandem mass spectrometry. Among those reporting drug use, 89% of samples were positive for MDMA, 29% for ketamine, 6% for methylone, and 4% for N-ethylpentylone. While over a third of samples were positive for at least one NPS, only 5% of participants reported recent NPS consumption. Read the full study here.
