When the person comes to that commission, there's a technical staff with psychologists and social workers, who collect a history for the person, trying to identify the needs and to understand if the person is in fact addicted to substances or is a mere recreational, occasional user. In any case, if the person has an addictive disorder, they are invited to join a treatment facility, but it's not compulsory. There's some work of motivation to address people to treatment.
Most of the people who are present at those commissions are not addicted, in fact. Most of them are users who are not really problematic, but the aim is to intervene before they become problematic, so to act on any factor in their lives that may lead to a more problematic way, to more problematic use, later on.
