I see a need for a government to facilitate access to clean good quality drugs, taxing them, and providing the support mechanisms to enable people to come off those drugs.
Just to emphasize, Portugal didn't legalize any drugs. It decriminalized drug use and possession.
Which mean you are not going to be judged and sent to prison, but you can still get fined, especially if you refuse the treatments they suggest.
Drug trafficking, defined as possession of more than the average dose for 10 days is still a crime.
