Joking aside, look at Singapore for a success case.
I'm not sure how Singapore fares, but Japan is also known for its hard-line drug policy. This just pushes the harm underground. Just because you don't see it, and society turns a blind eye to it, doesn't mean it's not there. tl;dr: the hardline policy towards drug use in Japan created a massive underground meth problem. [1]
[edit] It doesn't take much research to find out something quite similar is happening in Singapore, too.
> “People think drugs are very hard to get in Singapore, but actually before the pandemic they were everywhere, and even now there are people selling them.” [2]
Hardline policies don't reduce the harm.

The overall impact of alcohol on society is not because it is “much more dangerous than most”, but because it is consumed (and abused) by orders of magnitude more people than almost every other drug.
I think it's fair to say that alcohol does far more harm to the user than psychedelics.
I agree but also think that’s a very different statement from “alcohol is a much more dangerous drug than most”
Maybe that's true, but the genie isn't going back into the bottle as like 50 years of the 'war on drugs' has so clearly demonstrated.
The war on drugs started 18 June 1971 with Richard Nixon's declaration that drug abuse is “public enemy number one.” At this point, drugs seem more available than ever. I strongly suspect we would minimize harm in the reality in which we live (rather than the pretend reality where drugs don't exist) by acknowledging that.
