[Drug-facilitated crimes: prospective data collection in a forensic unit in Paris].

INTRODUCTION

Little is known about the rate of crimes that are facilitated by the administration of psychoactive products without the victim's knowledge. This study analyzes the cases collected over a two-year period in a forensic unit in Paris.

MATERIAL AND

METHODS

The study covers the period from January 1, 2005 and December /31, 2006. It includes crime victims who consulted for toxicological testing in the forensic unit of the Hôtel Dieu in Paris, after filing a criminal complaint describing symptoms suggestive of chemical submission (amnesia, impaired vigilance or behavior) and whose toxicological tests indicated the presence of a psychoactive product that they had not been aware of taking. The tests used chromatographic techniques on blood, urine, hair, and food or drink residue.

RESULTS

Toxicological testing identified 52 cases of drug-facilitated crimes, primarily for theft and sexual abuse (including rape). The psychoactive products were most often incorporated in drinks, half of them alcoholic beverages. Benzodiazepines accounted for 77% of the cases. Other substances, found more rarely, included antihistamines, neuroleptics, and GHB.

CONCLUSION

Appropriate samples must be taken from victims rapidly to enable toxicological analysis. Chromatographic analysis must supplement immunological analysis, which is not sufficiently specific or sensitive. The collection of this information must continue in order to quantify the phenomenon and monitor the emergence of new products.
