New Psychoactive Substances: A Hidden Problem in Mexico

Objectives: There is no epidemiological information available about the use of new psychoactive substances (NPS) among the Mexican clinical population. For this reason, we examined NPS use among patients in a treatment institution, on the basis of clinicians’ report. Materials and Methods: This was an exploratory study carried out during 2017 and conducted by means of a survey, to consult clinicians about which NPS were used by patients in the previous year. Results: It was found that all groups of NPS were present in practically all of the treatment units in the country. The groups of NPS most reported were that of ketamine and phencyclidine. Conclusions: The results show the need to evaluate NPS use through an epidemiological perspective among both the clinical and the general populations.
