It was with great interest that we read the article published by Dolengevich-Segal (Dolengevich-Segal et al., 2017), which provides an interesting review of the emerging phenomenon known as chemsex and the different drugs used in this type of practice.We would like to highlight the importance and usefulness of this paper, given the progressive increase in the prevalence of drug use in the context of sexual activity among men who have sex with men (MSM) in Western Europe (Fernández-Dávila et al,. 2016). This situation raises the need to launch epidemiological studies to assess the phenomenon - not only, however, from the point of view of mental health, but also from the field of infectious diseases and toxicology. We must not forget that this type of practice involves an increase in the risk of infection by sexually transmitted diseases and the problems that drug use can cause from the toxicological point of view. Both are causes of emergency room (ER) consultation, and more training in how to tackle the problems arising from chemsex should be provided.
