Public health monitoring indicates that cannabis use is prevalent in Europe. Although estimates should be interpreted with caution due to potential error, the best available data at present indicates that an estimated 3·9% of all adults aged 15 to 64 reporting past month use. There is a considerable variation in prevalence of use, ranging from 9·1% in Spain to less than 1% in Malta, Hungary, and Turkey. Approximately 1 in 7 past-month users were estimated to meet CUD criteria, with substantial heterogeneity between countries. In countries where cannabis use is more common, such as in the Netherlands and Spain, the share of users meeting CUD criteria appears to be lower than in countries where cannabis use is less common, such as Malta and Hungary. However, there are also exceptions to this, such as the UK, which has both relatively high rates of cannabis use and of CUD.
