I've used tobacco from a cigarette in a joint before. I personally think that smoking from a pipe gets you high, but smoking a joint with tobacco gets you stoned, because the tobacco calms you down. This is basically what I plan on everytime, so if I'm just going to chill with friends I'll roll a j with tobacco, but if I want to be fucked and go to the movies or the mall or whatever I'll smoke a bowl. I don't know, but that's how it works for me.
