Figure GPS-4. Trends in last 12 months prevalence of cannabis use among young adults (aged 15 to 34) [see all figures in this series...]

Part (i) All countries

Notes:

Sample sizes (respondents) for the 15 to 34 age group for each country and year are presented in Table GPS-8 part (ii).

Data taken from national surveys available in each country. Figures and methodology for each survey can be consulted in Table GPS-8 part (ii).

For ‘young adults’, the EMCDDA uses the range 15 to 34 years (Denmark and the UK from 16 years, Germany, Estonia (1998) and Hungary from 18 years). In France the age range was 25 to 34 in 1992 and 18 to 39 in 1995.

The most recent General population surveys reported by the Czech Republic display a wide variation in results, the reason for which is being explored, but may be due to differing sampling methods.  The data is provided for information, but given the lack of comparability between surveys should be treated with caution.
