However...The problem would lie with the huge increase in usage and people overdosing in the first few years.
Pot is one thing, I agree that it should be legal...but when your talking meth, blow, heroin...etc. That's another story.
You know how dangerous it is to make meth? And if it's legal, you don't think people will be trying to make their own?
If people want to mess up their own lives, what right do we have to point guns at them? We should help as many people that want help, and we should actively try to help people that don't desire help, but we shouldn't use violence to forcibly help people.
I see little difference between pot, heroine, meth, alcohol, tabaco, blow, etc.
To me, they are bad actions that people voluntarily subject themselves to. Why should we use violence against them?
Fundamentally, I don't believe that someone's sense of morality or sense of "health" should be enforced at gun point onto other people. That is true for drug use, insurance (or lack thereof), etc.
I think if its legal less people would try to make their own, as industries would spring up to do it legitimacy (and it could be certified by the FDA saying what is in it). Also it would help buster's war on robots (for a little while) as there would be more jobs.
