Marijuana vs Cigarettes

[Coop_DeVille]

Forgive me if this is posted in the wrong section.. I am new here.

I would like to know how smoking a small amount of pot compares to smoking cigarettes, in terms of cancer or other lung damage. To put it into perspective, if someone takes a couple of hits (short drags on a small pipe) a few times a week at night to help to get to sleep, can this cause lung cancer or other cancer problems?
