The war on illegal firearms kind of ties in with the war on drugs. It's the bigger gangs that usually get ahold and do them. Honestly it's like something GTA type. Not so fictiony, of course, but yeah. Cocaine is deprived from Coca... man made substances are added to it to make cocaine.
I know what you mean there. There's kids that're younger than me you can barely talk to. They're all slow talking. "heyyyy mayyn. wanna smoke sum weeeeeed?" it's ridiculous. Yes I've smoked before, no I haven't in a good while.. and don't plan on it. I had two blunts my first time and I had decent side effects. Next day at work was horrible, I couldn't remember anything. I've came out of that now, but yeah. I'm sure if you smoke TONS then you won't for a long time.
edit: Cannabis was originally used for healing, though. Drug abuse ftl.
