Chemsex, a specific form of sexualized drug use (SDU), has rapidly increased in the last decade. This phenomenon could result in a complex public health issue because of the heterogeneity amongst socio-psychological profiles of the practitioners, leading to the difficulty to target specific populations. Healthcare professionals need to be aware of this practice and its related risks to provide care adapted to the individual who consults. Here, we suggest that better knowledge of this field can help to improve prevention measures and provide information with a non-judgmental and respectful approach to those who practice chemsex.
