I think the system is being overrated both in the article and in your comments. I'm from Portugal (but that doesn't mean I'm an authority on the reality of my country, as I haven't been involved in this kind of situations and didn't experience the system working) but I just think the whole thing just comes down to "you're not punished for having it".

But that doesn't mean that there exist government production sites or distribution stores. So there isn't any advantage for the goverment such as incoming tax money from the drugs or increse in job positions.

Also there is no mistaken belief that the goverment supports the drugs perceived by the youth because actually all the system does is not arresting you, the goverment doesn't provide the availability of drugs.

If the system ends up helping the addicted individuals or not, that is something that I don't know. Though it seems obvious that arresting someone is not the wisest first step for treatment, I end up figuring how does the system reaches the addicts then (I don't think getting help by themselves is something they would do without a great external help).
