Notes:

This table aims to present an overview of national surveys. Exceptionally, some relevant regional surveys are presented. Some city surveys reported by countries were not included as they tend to produce higher prevalence estimates which are not comparable with estimates for whole countries (or large regions with both urban and rural areas). Athens was included as a reference point for the 1993 survey.

'Data collection' means 'data collection method used in the survey': 'interview' (face-to-face interview, which may include self-completed sections for the more sensitive questions, also it may include CAPI -computer assisted interviews), 'phone' (telephone interview), 'mail' (mailed questionnaire), 'Multimethod' (Multi-Method - simultaneous use of interview, mail or internet in the same survey).

'Survey sample' refers to the number of actual respondents to the survey (Net sample). In some cases, national surveys cover originally a broader age range ('original age range') than that presented here for the standard groups 'All adults'(15-64) and 'Young adults' (15-34). Sample sizes are presented respectively for the 'original age range', the 'all adults' and 'young adults' groups.

In surveys with small sample sizes results should be interpreted with caution.

Countries were asked to report results using, as far as possible, EMCDDA standard age groups (all adults: 15-64, young adults: 15-34). In countries where age ranges are more restrictive, prevalence estimates may tend to be slightly higher. Some countries have recalculated their prevalence figures using the EMCDDA standard age groups.

For methods and definitions on population surveys in general, see General population surveys of drug use – methods and definitions.
