Key messages

  • Rates of cannabis use remain higher among males than females in many countries
  • However, preliminary findings point to a convergence in male to female rates of cannabis use among more recent birth cohorts
  • Analyses of the full range of indicators of alcohol related harm are underway, however we found similar trends for rates of alcohol use and heavy episodic (binge) drinking, where male to female ratios are close to one in the most recent birth cohorts
  • Further analysis with the present dataset may highlight the way country specific changes in social norms have influenced changes in gender differences in substance use over the last century
