abstract: Drug consumption by adolescents causes social and health problem.
  
  
  OBJECTIVE
  This prospective study was designed to examine reasons for and against using substances such as tobacco, alcohol, and marijuana and to discover whether or not motives to use drugs vary with the number of drugs used.
  
  
  METHODS
  The participants were 886 adolescents from a suburban high school (Nancy, France), who answered a self-report questionnaire.
  
  
  RESULTS
  The response rate was 95% (655 males and 175 females, mean age 17.5 +/- 2.5 years).  The prevalence of current tobacco use, former tobacco use and never used was 40.7, 21.3 and 31.7%, respectively.  For alcohol consumption, the results wre 85.8, 3.5 and 0.7% respectively and for marijuana consumption 34.4, 18.3 and 47.3%, respectively.  Ecstasy had already been used by the respondens.  The main reasons given by the adolescents to explain why they did or did not use these substances varied with the mumber of drugs used.
  
  
  CONCLUSIONS
  This work shows an increasing deterioration of youths' social relations (with his/her parents and with him/herself) that seem to depend onthe number of drugs used.  Further research is necessary to improve these results.
