Prevalence of new psychoactive substances in oral fluid samples from French drivers

Currently, standard roadside testing in France is performed in oral fluid (OF) using an on-site immunological screening for drugs of abuse (DOA), specifically the Drugwipe-5S® from Securetec (OF screening test for ecstasy/amphetamine, opiates, cocaine and cannabis). In 2016 and in 2017, we tested French and Belgian drivers’ OF samples for new psychoactive substances (NPS) after a positive or negative roadside screening test for DOA. Here, we complete these data by updated results in French drivers’ OF sampled in 2018, 2019 and 2020.
