TY - JOUR A1 - Ihle, Wolfgang A1 - Lehmann, Katrin A1 - Esser, Günter T1 - Legale und illegale Substanzen im Jugendalter : Konsum, problematischer Gebrauch, risikoerhöhende und risikomindernde Faktoren bei 14- bis 15-Jährigen N2 - Use and misuse, age of first substance use, and prevalence of problematic use of legal (alcohol, nicotine) and illegal (cannabis etc.) drugs in adolescence were analyzed. The risk and protective factors for substance misuse were investigated. A representative sample of 246 14-15 year-olds were examined (20% of the population of a defined German region, cross-sectional design, self-rating inventory). Prevalence rates for problematic use were 19.9% for alcohol, 48% for nicotine, and 16.7% for illegal drugs. Mean age of first substance use was age 12 for legal drugs and age 14 for illegal drugs. 4,9% of the adolescents showed concurrent problematic use of nicotine, alcohol, and illegal drugs (male- female ratio: 5,2:1). Problematic substance use could be predicted best by a combination of risk factors (school failure, low level for availability of illegal drugs in the neighbourhood) and protective factors (participating a lot of sport, positive family climate). Suggestions for universal, selective, and indicated preventive interventions were derived.
