Prevalence of "High Risk" Opioid Use in Norway
"High-risk opioid users are a heterogeneous group that includes marginalised drug users with long-standing ‘careers’ of heroin use, as well as socially included persons who became addicted to opioids through excessive consumption of prescribed pharmaceuticals. The description of high-risk opioid use does not include stable patients in opioid substitution treatment (OST) or others using pharmaceutical opioids in accordance with a doctor’s prescription. Patients in OST who misuse prescribed drugs or other opioids than the prescribed one(s) shall be included, however.
