[Population of people placed in police custody, hidden barometer of diverted medicines].

PURPOSE OF THE STUDY: The population of people in police custody is a sentinel niche that is poorly represented in the "usual panels" of public health studies. The aim is to make an overview of their diversion of drugs.

PATIENTS AND

METHODS

A retrospective study based on cases of misuse in a sample of people in custody examined between 2015 and 2016 at the forensic medicine unit of the hospital Hôtel-Dieu-Paris.

RESULTS

Of the 5149 medical examinations, 302 were for substance use disorder or drug misuse. In 2016, the number of notifications for misuse of clonazepam increased (n=65); the user population appears to be getting younger (average age=23.5 years) and to be supplied mainly by deal (63%). Regarding opioid substitution treatments, the indicators of abuse and diversion are confirmed, while morphine sulfate stands out with a strong deal (>75%), IV injection (62%) and polydrug use, including methadone, cocaine (62%).

CONCLUSION

From our results, national surveys in general population and studies carried out in the context of deprivation of liberty, people in police custody constitute a real barometer of the parallel market for street drugs. Clinical impacts can be major; a better monitoring is needed. For caregivers, it is also a matter of better identification of misuse, substance use disorder for a future orientation of the patient.
