Portugal did not decriminalize use of drugs! Public use of drugs, and being uncontrollably high in public, is criminal and they use the court system to force people into voluntary rehab (the other choice is prison) where they use an evidence-based drug treatment system and up to a few years of job skills and counseling before releasing the person. Decisions are made by a panel of doctors and ex street-junkies who know the truth of the situation and what the addicted will say and do.
Portland Oregon on the other decriminalized the drugs - as in you can buy and inject anything in front of a cop and pass out in your own vomit in the middle of the sidewalk and the police can't even move you.
Regrettably they knowingly chose to reference Portugal as if they were following its advice while using the terminology to describe a completely different system.

That feels like the joke about Freud trying to cure Cocaine addiction with Heroin and merely inventing the speedball.
What do you think of Suboxone? It blocks withdrawal symptoms and the further effect of opioids, making users not suffer or want more drugs during the process. At the end, the user is not dependent or addicted, and is ready for actual rehabilitation.
