There is dumb high school kid OD, the drug they think is safe is actually laced with too much fent. I assume you aren’t going to let these kids buy from legit sources anyways, so I’m not sure how they are avoiding buying from the homeless encampment next to their city bus stop (something that actually happened here in Seattle). Then there are people that don’t care, and do as much drugs as they can get their hands on, the people who are in crisis all the time.

If you can’t go after the users, you have to find some other way to get to the dealers. Portugal has that problem, since they can’t go after use, the police aren’t finding an effective way to go after dealers either.
