[Comorbidity of substance abuse and antisocial behavior. Analysis of an adolescent psychiatric population].

Comorbidity, the simultaneous occurrence of different psychiatric disorders, is a common phenomenon in child and adolescent psychiatry. Usually, it affects the prognosis negatively. For example, drug abuse increases the risk of drug dependency among adolescents with conduct disorders. In this study, a high-risk group of 30 adolescents with conduct disorders at a regional psychiatric hospital was examined regarding drug abuse. Half of the adolescents were taking drugs. This influenced the course in a way which limited the therapeutic possibilities. The comorbidity of drug abuse and conduct disorders is discussed in connection with prevention.
