While there is some truth to that, I think that cigarette and alcohol companies simply have great lobbyists.

If cocaine was legal at some point and they had great lobbyists, it would be legal forever.

I'm very libertarian on this issue. Let people do what they want provided there isn't significant risk to the public (i.e. driving an 18 wheeler while tripping on mushrooms).

Cocaine was sorta legal in the past (coke Cola anyone?) but I otherwise agree. My body my choice, doesn't mean I can manufacture, distribute, or be publicly slammered under the influence, but if someone wants to snort a line, well (please note I also do not support hard drug use)
