Estimated Number of Problem Drug Users in Sweden
"Based on register data from the patient register and from the Prison and Probation Services, it was estimated that there were 29,500 problematic drug users. This corresponds to 38 per cent of the 77,000 people who confirm regular use of illicit drugs in the population survey, or 23 per cent of the 127,000 people who regularly use some type of illicit drug or presomption medicine without a doctors prescriptive [sic]. This means that there is a large group of people whose regular drug use does not lead them in to the health or corrections systems."
