The latest study on cannabis use among the adult population by the French Observatory of Drugs and Addictive Tendencies (OFDT) is painting a picture that sometimes goes against conventional wisdom. Among under-25s, all indicators have been on the decline since 2017, whether they concern experimentation – down 5.5 points compared to the 2017 study, from 53.5% to 48% – or habitual use, which is down 2.1 points between 2017 and 2021, from 8.4% to 6.3%. Conversely, more people are reporting cannabis use over the age of 35, and even more so over 45. Despite the recent decline in the appeal of cannabis among under-25s, France remains firmly established as one of the European countries where this drug is most widely used.
