So, unpacking your worldview here, how do you feel about cancer brought about by smoking, or by prolonged exposure to materials that you know are radioactive and/or carcinogenic? Does that change with the knowledge that processed meat and plastics, things that are impossible to avoid unless you structure your life around limiting exposure to them, are most likely mild carcinogens?
Also, please tell me, regardless of how you classify addiction, that you at least understand that the only evidence-based approach to drugs is decriminalisation. Almost all of the societal ills associated with them are entirely the fault of their possession and sale being crimes. You can’t find safe environments to use them in if they’re illegal, nor can you feel safe seeking medical aid if you’ve taken too high a dose without realising it. If you’re a dealer, you have no regulatory bodies to answer to, and pay no taxes on the money you make. If you’re running organised crime, you’re already sitting on enough of a supply to land you in jail for the rest of your life, and that makes murdering competitors seem like a much more palatable option. And then there’s the developing world. Most of the money this makes ends up back in the hands of rebels, warlords and cartels in the developing world, where they cause untold misery and suffering.
But if you legalise them, that nips most of those problems in the bud. You can publicly admit to using them, feel safe seeking medical aid when you mistakenly take too much, get help from programs designed to end your dependence. The dealers go out of business, replaced by actual stores that pay taxes and follow regulations, like not being able to sell to minors or water down your product to sell more of it. Organised crime loses one of its biggest sources of money overnight, given that their expensive material of unknown origin and purity is suddenly replaced by cheaper material of known origin and purity. The cross-border smuggling also ceases, because what else are you going to find that is illegal, compact, and high in value? Oh, and the developing world can actually benefit from drug production, since the criminal groups will be greatly weakened from the loss of profits, and developed world importers would rather deal with legitimate businesses than violent criminals and rebels.
We learnt this shit a century ago with alcohol, one of the most destructive drugs (even meth would not be as destructive if legalised), why are we still doing it?
There is something to be said for using squat toilets instead of sitting toilets in public bathrooms, so long as there are properly cleaned sitting toilets for the elderly and disabled (I have seen some shocking disabled public bathrooms over the years)
