@ Drug legalization:
Legalization of ALL drugs is suicidal, literally, those things aren't even supposed to be consumed by humans some of them would kill the person withing the first uses. The rest either results in dependecy or severe health problems(which also lead to death except more painfully).
The only one I think should even be considered to be legalized is marijuana as it's one of the least prejudicial. I'm not someone who likes alcohol, cigarettes or drugs in general, and if it was up to me, they'd stop existing, but they do, so you need to keep control over them, people are going to find a way to get what they want, and if it's not gonna be on a convinience store, they'll find a drug dealer.
Legalizing it would not only mean it'd be supervized to ensure quality(you'd be surprised to know how much weed there actually is in those things going around) but also significantly reduce crime rates and boost the economy.
And this is not just a "it isn't a crime anymore so the rate doesn't exist anymore", just look at Prohibition and how it backfired with the Mafia.
Still, as someone who is utterly disgusted by these, I believe there should be some enforcement against their use in public areas.
We all know the problem with passive smokers and the **** drunk people do so I don't think I have to say much in regards to that.
