Prohibition would reduce the number of potential people in that situation. For the people that inevitably would fall into drug abuse and addiction is where social programs come into place.

All the dangers you listed for prohibition are handled by social programs, decriminalisation of users and harm reduction. Here there are many places you can go to test your drugs for free to know if they are adulterated with dangerous substances or not. No question asked.

I don’t know the waiting periods for these treatments. But they are irrelevant to prohibition/legalization, they are not going to get extra help or quicker help because hard drugs are legal.

All these being said I don’t see any single thing that’s worse here because hard drugs are illegal.

Also we have the example of tobacco. While legal here there was a time when ilegal tobacco dealing was very big, because it was cheaper. With hard drugs would happen exactly the same. Ilegal would be cheaper than legal so most points about reducing gangs and drug-dealing related crimes would be defeated.

Users are not criminalised, so they can get help. Help is free for them, and there are plenty of social programs to get them out of that world. There are free points for drug testing, so they don’t use adulterated substances. Drug related violence is not a big issue here. There’s the typical marginalised violence in some neighbourhood, but I don’t see how making drugs legal would solve anything there. The only people being prosecuted here are drug dealers, which to be fair are making money by destroying people’s life so they kinda deserve being declared criminals imho.

There would always be drug addicts, but I don’t see how situation would be made better here by legalising those drugs. By keeping them illegal at least you reduce the potential drug users who would fall into that horror.

All this for hard drugs of course. Soft drugs should be legal, for moral reasons. Here they are partially legal. There use to be some places where you could legally get weed but they are in a gray area. Anyway marijuana is so common and personal use in your own home is perfectly legal. Thought I think in this case it should get the same status as alcohol.
