New psychoactive substances (NPS) are substances that have recently become available, and are not worldwide regulated. They often intend to mimic the effect of controlled drugs, becoming a public health concern. In 2014, 101 substances were reported for the first time in the EU, which may require to be studied and risk-assessed by the scientific community. The EMCDDA recognizes it as an emerging topic where research is most needed, as the scientific community is struggling to keep pace with the speed at which new substances appear. On the one hand, case reports and internet-based surveys are quickly published but do not provide enough evidence to guide clinical decisions. On the other hand, classical high-reliability methodologies such as Cohort and Clinical studies take too long and their cost is too high to be of much use for the study of NPS. We propose an intermediate methodology to tackle this unmet need. González and colleagues described a set of highly educated, experimental users of NPS with extensive knowledge and consumption of substances. These users usually look for drug checking of the substances they intend to consume. We suggest we could benefit from the collaboration of such users, and the possibility of obtaining analytical confirmation, to retrieve information about NPS in a quick and reliable fashion. Recluting of subjects that submit NPS to a drug checking facility. Analysis of the samples for analytical confirmation. Check inclusion criteria and propose inclusion in the study. Give structured forms for reporting effects and adverse events.
