A new study by the Journal of the American Medical Association found that daily use of marijuana has been linked to the development of certain cancers.
The largest study of its kind has unexpectedly concluded that smoking marijuana, even regularly and heavily, does not lead to lung cancer.
The new findings “were against our expectations,” said Donald Tashkin of the University of California at Los Angeles, a pulmonologist who has studied marijuana for 30 years.
“We hypothesized that there would be a positive association between marijuana use and lung cancer, and that the association would be more positive with heavier use,” he said. “What we found instead was no association at all, and even a suggestion of some protective effect.”
True, but it’s not that simple.
Where is this from? That contradicts what the article saysm
The article doesn’t talk about lung cancer.
I’ve posted the link to the article I quoted in another comment.
