Yeah. It's not something either you or I are expert in, and it's a complex problem. But any time we have prohibited a substance in the USA, it has only increased its availability, and created a violent and profitable black market supply chain.
And, knowing the US Politician's tendency to stick a band-aid on major problems, and then run far away crowing about how they fixed it... I don't want to give them more power over a weakened and victimized populace that's already got a hard enough time fighting addiction, etc.
Make the politicians focus on the real issue, and don't give them an "easy out" or untenable platitude like, "Heroin is bad, mmmkay?" Prohibition has never worked for us. Liquor, drugs, nukes. It always fails and creates much worse secondary effects.
