In an 8-year longitudinal study, 368 pupils of the Jona-Rapperswil Vocational School aged between 15 and 17 years were subjected to a combined medical-educational half-yearly health education action against luxury articles and habit-forming substances in groups comprising the classes of each individual year. Before group session 34% were smokers, after the intensive instruction 23%. Before the session 62% drank, afterwards 34% took alcoholic drinks occasionally. No pupil had tried drugs during the six months instruction; the number of drug-takers remained constant at 3%. However, the desire to try a drug out of curiosity rose from 22% to 27%.
