Injection drug users (IDUs) entering an urban low-threshold opiate detoxification unit in Munich, Germany, between 1991 and 1997 were asked for lifetime suicide attempts and administered a questionnaire, including sociodemographic, IDU-related, and drug user treatment related variables. Among 1,049 participants, 20% had ever tried to commit suicide. In the logistic regression, female gender, older age, drug user treatment experience, lack of drug user counseling, and emergency treatment were associated with attempted suicide. Regular screening for suicidal behavior in IDUs should be undertaken with a special focus to mention risk factors. The study's limitations are noted. This study was partially sponsored by the German Ministry of Health.
