Also, it didn't really fix the drug abuse problem. It did help a lot with the social consequences of abuse by removing obstacles to seek help (or provide help).
The drug abuse problem was not completely fixed but at least it shifted the principal caretaker of the problem from the security forces to the social security.
In my view these were the main factors for the relative (and undeniable as per [1]) success of the Portugal approach:
- Decriminalizing the use and possession without the intent to distribute (the measure that gets all the credit)
- The harm reduction program [2] with measures like needle exchanges, safe rooms for drug injection (popularly known here as "salas de chuto", roughly "kick rooms"), methadone clinics
- Relocation, requalification and housing programs to vacate popular drug hotspots like, for instance, Casal Ventoso (before [3], after [4])
It is interesting because in the span of one generation heroin consumption turned from "cool, rebelious and chic" (like in Kate Moss heroin chic) to a bums drug, provided by the government to the ones that lost their ways.
This change in perception helped to break the cycle of graduation from light drugs (like cannabis) to hard drugs (like heroin) in the youth and most likely is a significant factor in the success of the portuguese approach.
Kids won't touch the hard stuff because they can see very clearly based on who ends up in "salas de chuto" or in the methadone centers the harmful effect of the drug.
