"In France, a study conducted by the French Addictovigilance Network clearly showed a 2.5‐fold increase in the number of ketamine users among people with substance use disorders between 2012 and 2021 [9]. This finding is even more alarming given that the number of daily users, users with distress at discontinuation and users with addiction were also found to be increasing. In 2023, it was estimated that 2.6% of adults aged 18–64 in France had experience with ketamine [8]."
