The government see's that drugs are illegal for a reason. I could care less if someone wants to fry their brain doing some retarded drug, butttttt being that they did the drug and fried their brain they decide they can drive or do whatever. That's when innocent people die.
I guess if you were locked in your house sureeee do all the drugs you want! OD if you want I don't care lol. Just don't bring anyone else down with you.
Edit:
If they were legal, then they would be a whole lot easier to get. That will lead to more people doing it. That would probably lead to a "more" fucked up community. I say "more" because every community is fucked up to some level. Legalizing will just increase it I think.
