Figure 23 Recent (last year) use of cannabis among young adults (15–34 years old) in Europe and the USA

Notes:

In the USA, the survey was conducted in 2003, and the age range is 16‑34 years (recalculated from original data).

In the European countries, most surveys (17 out of 19) were conducted between 2001 and 2004, and the standard age range is 15‑34 (in some countries the lower end may be 16 or 18 years).

The European average prevalence rate was calculated as the average of the national prevalence rates weighted by national population of 15‑34 year olds (2001, taken from Eurostat).
