The Norwegian Public Health Act (§10.2) permits involuntary interventions for adult patients with SUDs. The act includes an option to retain the patient for up to 3 months, when voluntary efforts are insufficient, and the health of the patient is seriously at risk, due to extensive, prolonged substance use. In Norway, patients with SUD, whether voluntarily admitted or involuntarily admitted, are often treated in a single ward, and they receive the same types of therapy. In the acute phase, the main goal of retention is to provide life-saving treatment. Over the longer term, the aim is to motivate patients to enter voluntary treatment and engage in long-term recovery .
