Researchers find no link between marijuana and lung cancer

Researchers surprised to find no link between marijuana, lung cancer / Study's findings apply even to heavy pot smokers

Now all we need is a study to determine whether naturally grown and unprocessed tobacco has a direct link to cancer. The assumption has always been that it is the naturally occuring tar in the smoke that causes cancer; but since marijuana contains tar as well it either isn't the direct cause or its effects are negated by something else in marijuana smoke. With all of the chemicals added to American cigarettes during the curing and manufacturing process, it would be of little surprise to me if the cancer causing agent was a result of chemical processing and not part of the tobacco leaf's natural makeup. It would be an interesting twist if tobacco, as smoked by Sir Walter Raleigh, is safe and that it is actually tobacco companies that cause cancer. 🙂
