Many studies indicate that a large number of addicts commit crimes and, conversely, many offenders are addicts. Individuals who fall into both these categories show clear bio-psychosocial problems. With few resources at their disposal, professionals from both the Department of Health and Social Services and the Department of Public Security feel uncomfortable trying to help these individuals. This study presents the results of 6 focus groups on the types of services that should be offered to addict-offenders. Results indicate that proper assessment of the addiction and the addict-offender's motivation to undertake rehabilitation is essential. Another crucial element is an open channel of communication among the various professionals involved in the case management and treatment of these individuals. Finally, a good reference system is needed. However, the authors insist on the caution that must prevail when control and help are provided together in a concerted effort.
