Regular cigarettes can cause lung cancer, but what about using marijuana

Regular cigarettes can cause lung cancer, but what about using marijuana?
It's used legally for medical reasons, but I've heard nothing as to the effect it has on the lungs. Is it worse or the same as cigarettes?

ive heard its either worse or the same.. but not better
2 :
smoking ONE joint is the same as smoking four or more cigarettes. so its FOUR TIMES as bad. don't do it. =)

I've heard the latest statistic suggesting that one joint is equal to 5 cigarettes. That doesn't say much about the size of the joint, or if you're smoking the whole thing all by yourself. I think they're probably equally damaging when you consider that cigarettes are chock full of harmul chemicals whereas marijuana is pretty "all natural." Even so, marijuana is very tarry and much stronger than cigarette smoke, causing most people to cough each time they inhale it. So, while it might be all natural, the smoke is probably just as, if not more damaging to the lungs.

I've heard it could be worse. But, just taking the smoke in can't be good.
5 :
Marijuana smoke has been found to contain more cancer-causing agents than is found in tobacco smoke. Examination of human lung tissue that had been exposed to marijuana smoke over a long period of time in a laboratory showed cellular changes called metaplasia that are considered precancerous. In laboratory test, the tars from marijuana smoke have produced tumors when applied to animal skin. These studies suggest that it is likely that marijuana may cause cancer if used for a number of years
