Ok, so I don’t get adulterated drugs, that still doesn’t do anything for the addiction.
Are we then going to actively discourage people from doing drugs? If so how? What effective form does that take?
Those who understand addiction, either first-hand or through research, understand that the root problem is not the drug/habit; the drug/habit tends to be the addict's best known way to sooth immense psychological pain. Shame drives addiction in deeper. So to actually help addicts, one needs to destigmatize the conversation, allow people to say "Hey, I'm in a bad place and I need help" with minimal fear of being judged (the addict tends to already hate their self pretty profoundly). And given how human nature works, destigmatization depends on legality.
Stopping addiction isn't about judging addicts; it's about understanding the root cause of their problem (which tends to be intense emotional trauma) and giving them empathic help to start building healthy relationships.
Also, trauma is not always a cause for addiction. Lots of people suffer trauma and don’t get addicted, conversely we also have people with little trauma who get addicted.
In 200 years history of drug suppression literally everything has been tried.
And yet, even in a high security prison, drugs are highly available.
If it can't be done in a max-security prison, how do you think it can work for a whole society?
What method of restricting supply has not been tried. The US has literally invaded other country to try to destroy supply bases. The military as whole division, billions spent on intercepting submarines.
Absurd high cost have been put on a dealer that is captured.
What is your solution to actually restrict supply in a meaningful way?
It isn't a 1:1 causal link--virtually nothing is. But there's very strong evidence that unprocessed trauma is one of the core drivers of addiction.
It's constructive to think of drugs and addictive behaviors as emotional crutches. You don't help people with problems walking by making crutches illegal; you do so by focusing on treating the root cause, which may include taking the crutch away in a properly supportive therapeutic environment.
I'd also point you to the experiments dubbed "Rat Park" (https://www.psychiatrictimes.com/view/what-does-rat-park-tea...). Addiction is ultimately a social/emotional disease; the drug/habit is the symptom.
Making drugs legal means that one can control the points and conditions of distribution. So one could require licensing, education, or even controlled application. Sure, you can take good, cheap, heroin, but you have to take it here.
Of course, the more onerous the path the get legal drugs, the more appealing illegal drugs become, so there's a safety -maximizing point somewhere along that integral.

We've all witnessed the war-on-piracy that the powers-that-be have been pursuing a few decades ago, and we've all seen it fail spectacularly. Similar to the drugs story, by going after the Napster-type filesharing systems, they created a much more lucrative black market where criminals made millions by being the first to crack protection schemes.
What reduced the problem to a manageable level? Apple Music/Spotify/Netflix. By making it legal to do entertainment in the confines of their own home, the harm to society at large was much reduced. And even better, because everything is legal now, production companies have much better insights into their market, and can better produce content that their users actually want.
yes, addiction is bad. fix the root cause of drug use instead of pretending you can fix the world with inefficient laws.
Also consider places like the Netherlands or various states in the US where cannabis is legally available. What you see there is that other drug use shifts to cannabis which is relatively safer than alcohol or opioids. You also see declining rates of use among teenagers as it become less mysterious and dangerous but rather common and uncool.
As for actively discouraging people, we are actively discouraging people from using tobacco. And it seems to be working pretty well.

Here's a good read on how Portugal has handled things (to quite some success): https://time.com/longform/portugal-drug-use-decriminalizatio...
It's easier for a 15-yo to buy weed than to buy alcohol (where weed is illegal, I should add).
