Introduction and Aims: In France, the law states that any person held in custody could be examined by a doctor. The main objective of the medical examination is to give medical evidence of health compatibility with custody. This review identifies health risks such as addictive behaviour. We wanted to know which psychoactive substances are used in this particular population, and how problematic these uses are., Design and Methods: A prospective, monocentric, open-ended study conducted via a structured questionnaire was carried out on detainees who reported having taken drugs or illegal substances. Practitioners investigated desired effects for each substance, and characteristics of use, by means of the dependence criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994). Problematic use was assessed when at least 3 items of the DSM IV were positive., Results: 604 questionnaires were examined. 90.7% of questionnaires reported tobacco use, 76.2% cannabis, 57.3% alcohol, 12.5% psychostimulants, 10.0% opiates and 0.7% benzodiazepines or Z-drugs. The frequency of problematic use was 74.6% for opiates, 44.9% for cocaine and 25.3% for cannabis. Compared to non-problematic users, problematic users were older, more likely to be jobless without financial means, more likely to have a medical history, including a greater likelihood of mental illness, and more chance of undergoing prescribed medical treatment. They included more women and more homeless people., Discussion and Conclusions: These results show characteristics of psychoactive substance use in a sample of people in custody. Psychoactive substances mentioned by respondents are not different from those observed in the general population, but for certain users, the desired effects are far from the pharmacologically expected ones. For some, taking substances seems to be part of their way of life, for others it is a means to compensate for an underlying feeling of uneasiness. Furthermore, problematic users present severity criteria which seem to be greater than in psychoactive substance users in the general population., (Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Introduction: There are no studies on medically examined persons in custody which specifically focus on identifying dependence profiles among users of intoxicants. Nonetheless, the characterisation of dependence profiles for intoxicants such as alcohol, cannabis, cocaine, heroin, amphetamines and their by-products is a medical necessity in this setting., Materials and Methods: A prospective, monocentric, open-ended study conducted by structured questionnaire was carried out on detainees who admitted to having taken an intoxicant/s (tobacco, alcohol, drugs or illegal substances). Social, legal and medical data were collected. The aim of the study was to explore characteristics of these persons in police custody., Results: 817 questionnaires were examined. More than one-third have a dependence on at least one substance. 37.7% were dependant of tobacco, 86.5% of drinkers, 24.7% of cannabis users. Of these, 90.1% were from men with a mean age of 29.4 years, 40% from individuals living alone, 25.7% from persons with no financial means and 19.6% from homeless persons. 10% were believed to be suffering from mental illness, 7.2% were thought to be asthmatic, 3% to have a chronic infection, and 2.9% to have epilepsy. 36.2% reportedly received treatment, 37.5% of which included benzodiazepine and 20.3% opiate substitution therapy. Incidence of psychological and psychiatric disorders is close to 10% of intoxicant detainees., Discussion: In this study, some of the stated pathologies occur in ratios similar to those in other published results. But, there is a high, and probably underestimated, prevalence of psychological and psychiatric disorders in this population of detainees reporting exposure to intoxicant or illegal substances., (Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.
