Public Health Scotland has published data on hospital activity related to illicit drug use between 1996/97 and 2019/20. The data show that drug-related hospital stays more than tripled over the period, increasing from 87 to 282 per 100,000 population. Almost half of all drug-related hospital admissions (49%) involved opioid use.
