I can tell you that there are over 4000 chemicals in cigarettes that not only kill you, they cause more addiction to the nicotine...nicotine is relatively harmless....there's a lot more nicotine in marijuana than there is in tobacco....but marijuana (even though it has tons of chemicals) is not treated by man in a factory as is tobacco....cigarettes contain cyanide, ammonia, and thousands of unnatural chemicals...so even though marijuana has chemicals, it's all naturally synthesized within the plant....chemicals in cigarettes, I would say, are more harmful than chemicals in marijuana. The only other factor you want to take into account is the filter; you smoke tobacco through a filter with cigarettes, but not at all with marijuana...so that's a factor.

I personally think it all weighs out...they're probably both just as harmful as the other in smoke form...you're oxidizing thousands of different chemicals with that sudden fire with both substances...

But to sum it up, if you were to take tobacco out of cigarettes and smoke it filterless, say, in a bong or pipe, it would probably kill you a lot faster than pot would....

The nicotine in cigarettes is free-based with ammonia, much the same way cocaine is free-based with baking soda to make crack...so it's 100 times more potent and 1000 times more addictive...
