It's already illegal to drive impaired, doesn't matter your intoxicant. It could even be legally prescribed by a doctor.
But it's much more legal to sell alcohol than it is any other drug. Put the onus on the drug sellers to provide a safe controlled place to consume... which I hope comes with some legality and maybe some access to the banking system.
Nope, try suggesting that in much of the mainstream/popular internet and you'll be immediately pounced on for discriminating against the homeless (and then the people who said that will get pounced on for saying homeless rather than "unhoused"). "So you think it should be legal for rich people to get high but not poor people". Pretty soon someone will bring race into it too.
Honestly it seems to me like that stuff is happening less and less often. It just comes with not talking to literal children all the time. I'm all for privacy but i think in these arguments we should really be allowed to know who is 14 and who isn't. I think a big part of the toxicity and radicalism on the internet is that we're now having to have political discussions invaded by literal high schoolers. No one would privilege their ridiculous opinions at the Thanksgiving dinner table
The issue with drug criminalisation is that people get arrested who weren't going to hurt anyone, weren't any threat to themselves, haven't done anything objectionable and nevertheless were risking prison. The wins on that front should be preserved.
