The purpose of this research is to identify the New Psychoactive Substances (NPS) that are responsible for intoxicating patients in ski resort during winter activities.

The New Psychoactive Substances expose to an additional risk of overdose or death due to their potency. These New Psychoactive Substances are used voluntarily by users wishing to test new substances, but also involuntarily because of association (unknowingly users) with more "conventional" drugs such as cocaine or heroin in the self-administered powder. These intoxications are still poorly known and the investigators believe that the identification of New Psychoactive Substances among the drugs consumed, and the association of their consumption with the appearance of a particular symptomatology allow the physician to guide the diagnosis and facilitate the care of future patients.
