"Furthermore, drug-related treatment coverage is lower among women than it is among men in all five global regions. About 1 in 18 women with drug use disorders received treatment globally in 2022, while the number was 1 in 7 for men. In regions like Africa and Asia, men in need of drug use treatment were over five times more likely to be treated than women, while in Europe men with drug use disorders were more than twice as likely as women to be treated."
