This would be solved if drugs were decriminalized and testing kits were very easy to use and come by but I guess a lot more people have to die before society as a whole acquires common sense
Drug abuse is a much smaller problem in east Asia where it is intensely criminalized. In Singapore drug trafficking is a capital offense. Drug abuse is a massive problem in those parts of the US where it is de-facto decriminalized on the west coast. I think the evidence is fairly clear on what would constitute a solution, rather the debate is on whether we’d be willing to pay the costs of that solution.
