title: Substance use among adults 35 years of age: prevalence, adulthood predictors, and impact of adolescent substance use.
abstract: OBJECTIVE
  We examined the prevalence of substance use among American adults aged 35 years, and we considered adulthood predictors and the impact of adolescent substance use.
  
  
  METHODS
  National panel data were drawn from the Monitoring the Future study. Logistic regressions were conducted to assess the impact of demographics, life experiences, and adolescent substance use on smoking, heavy drinking, prescription drug misuse, marijuana use, and cocaine use at 35 years of age.
  
  
  RESULTS
  Factors related to increased likelihood of substance use include high school use, unemployment, and noncustodial parenthood. Lower use was associated with being female, a college graduate, a professional, married, or a custodial parent.
  
  
  CONCLUSIONS
  Among those aged 35 years, substance use was still rather prevalent and was a function of adulthood roles, experiences, and previous use.
