Brief summary

The study aims (i) to identify which substances leading to hospitalizations at Mayotte are also called chimique and (ii) to correlate these substances with clinical pictures in order to favor a better approach of the treatments.

Detailed description

The CEIP-A of Bordeaux (in charge of French overseas departments) has been commissioned by the MILD&CA in 2015 to reinforce the links between local caregivers and the addictoviligance's inquieries. In particular, the CEIP-A has been alerted about a drug called chimique in Mayotte, leading to many hospitalizations. Most of the patients are less than 18 year old or are young adulthoods. For all patients who have agreed to participate in this study, the remainder of the blood sample will be reused for a drop of blood on blotting paper; the remainder of the remainder will be stored in the heparinized tube. Medical data collected in the emergency department will also be collected. All the data will be analyzed by the pharmacology and toxicology laboratory of the Bordeaux University Hospital
