Look, you shouldn't even forget around with drugs in the first place.
My brothers friends ended up in jail by drugs. And those same people helped raise me when I was a kid!
Just because it's illegal doesn't mean it's morally wrong.
I mean, saying that is basically "drugs should be illegal because they are bad because they are illegal".
Also, "drugs" is highly generic, some drugs save lives, some do little at all, the only "drug" discussed in this topic is Marijuana, so refer to that only.
Also, the discussion here probably died out a few days ago.
