Alright, then whats the most common drug on earth (I don't know)?

in use, sell or production?

My friends and I think it's cocaine. (Not that we use it)
It's even in Coke.

It used to be in coke. I don't think it is still in there.

yeah cocaine is used a lot, mainly in rich countries like America/Europe etc.
Oh and of course in Cuba, the dominican republic and Jamaica.
But I guess, that meth is also used as much as cocaine recently.

It would be weed, because its a 'recreational drug' but I personally dont think its a drug.
I would say heroin actually.

Cocaine for sure,and weed.

My family finally ate in a fancy restaurant. Pizza, pasta and bread. I had none of it. Why? My fucking braces.

Where I live, my city of course has drugs but ask Nickone about drug central and he will tell you all about what is in this city that makes it what it is.

@Granby: I dont think weed is the most used drug, because the cocaine and heroin rate inceased dramatically over the past years. So did meth. Those drugs are mostly used in big cities and countries like the USA (from the Mexican border) or China & Japan. But weed is already a very common one because it is soft, rather cheap and there is no lethal-dosis.

Nevertheless I think cocaine is the most, followed by meth, weed and heroin.

#edit: we're forgetting about another big drug: XTC. I guess it'll be after weed
