This table aims to present data on school students obtained from national surveys. International comparability is based on standardisation by target age group (mean age 15.5), cluster sampling methods with the goal of more than 1500 participating students from the target group. Questions about cannabis use are based on the ESPAD survey questionnaire, data collection in the schools, and assurance of anonymity. Caution is recommended regarding some data in specific countries.
Caution is required comparing figures due to methodological limitations. For methods and definitions see Methods and definitions: youth and the schools population.
