Description of several original cases of chemical bids, either by the operating mode used (victims of specialized Internet sites), or by the nature of the substance used (Ayahuasca decoction), documented by the toxicological analyses. Case 1: Outside victim 5, where non-contemporary zolpidem catches of the facts are suspected, the results of the hair analyses are compatible with single doses of zolpidem (and alprazolam in victim 5), thereby objectiving chemical submission by these molecules. Cases 2 and 3: The analyses allowed to document and concertify chemical submission by zolpidem in a silver theft (case 2), and rape (case 3) by means of Ayahuasca beverage in an initiative ritual context. All the questioned have recognized the facts.
