Quote:SAN DIEGO, May 24 â€” Smoking marijuana does not appear to increase the risk of lung cancer or head-and-neck malignancies, even among heavy users, researchers reported here.
Quote:They found that the heaviest users in the study had smoked more than 60 joint years worth of marijuana (One joint-year equivalent to 365 marijuana cigarettes or one per day.), or more than 22,000 joints in their lifetime. Moderately heavy users smoked between 11,000 and 22,000 joints.
"That's an enormous amount of marijuana," Dr. Tashkin said.
Despite the heavy use, "in no category was there any increased risk, nor was there any suggestion that smoking more led to a higher odds ratio," he continued. "There was no dose-responseâ€”not even a suggestion of a dose responseâ€”and in all types of cancer except one, oral cancer, the odds ratios were less than one."
One more excuse for not legalizing shot down!
Smoke 'em if you got 'em!
I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children… - Wendell Berry, 1971
