Marijuana and your lungs
Friday, March 23rd, 2007Dear Julius,
I've heard that if you smoke marijuana, you're putting yourself at a greater risk for lung cancer than if you smoke tobacco. Is that true? If so, how harmful is it?
No, it's not true. I say that tenatively, since there is a catch, which I'll explain in a second.
It's not true, in that if you smoke marijuana regularly, and even if you are a heavy user, you are at no increased risk for lung cancer. The University of California at Los Angeles recently concluded a rather large (1,200 people) study on marijuana's link to lung cancer. They found that marijuana use has no corellation to lung cancer.
