abstract="A representative, stratified sample of ninth-graders of comprehensive school 1968 were followed retrospectively and prospectively in files from hospitals and Social Welfare Administration and in other official registers. Those who had stated high-frequency drug use in a school questionnaire, those who had attended special classes or had dropped out of school appeared to a larger extent than the average ninth-graders in social and child psychiatric registers during childhood. Over a follow-up period of 11 years they had a large over-consumption of drug-related psychiatric and social care. They were more often sick-listed and assessed to be without income than the average year cohort. The women had children before 20 years of age and the men were exempted from military service to a higher extent.<p /><p>Language: en</p>",
