Notes:

 Those that declared having used cannabis in 20 days or more in the 30 days previous to the interview are referred to as 'daily or almost daily users' in the texts. 

 (1) For United Kingdom frequency collected as frequency in the last 12 months but analysis presented is based only on users in the last 30 days. Data refer to 16 to 24 years.
