Hmm...the information I'm finding now is interesting. It says that IF marijuana smokers and cigarette snokers had the same amount of exposure to their substance of choice it would be worse, but on average the marijuana smokers smoke about 4x a day whereas the cigarette smokers average closer to 25x a day... Interesting stuff, I hand't thought about that before.

Bleah, I kept thinking of more things to add.

Edit: Just like this...Here's a good article...
