Their "dissuasion commissions" made up of lawyers and social workers do not have the power to mandate compulsory treatment. They either recommend treatment or community service for addicts and if they refuse the commission can issue a sanction such a fine or taking away personal possessions.

Authorities can't forcibly drag addicts into treatment but once they voluntarily consent to treatment they have conditions for release, you can't just check yourself out any time if you have a history of overdosing. Apparently 85% of their addicts voluntarily agree to treatment when asked to by a dissuasion commission.
