Despite numerous studies done on the benefits of marijuana, some are asking for a study on how marijuana smoking can affect the lungs.
There is no large study that shows a direct link between marijuana smoking and lung cancer.
Dr. Jenifer Marks, a general thoracic surgeon at the Medical Center of Aurora in Colorado, believes the questiona bout lung cancer and marijuana smoking is a public health question.
“They are exposing their lungs to foreign materials and foreign irritants that can lead to several known lung conditions. And although we don’t know that lung cancer is one of them, it also took us a really long time to prove that cigarettes and tobacco lead to lung cancer,” Marks said.
“Case is closed,” said Mason Tvert, at the Marijuana Policy Project in Denver. He believes the question has been asked and answered.
Tvert cites the National Academies of Science, Engineering and Medicine, and studies by UCLA professor Donald Tashkin.
“The longest, largest studies that have been done on cannabis smoking and cancer have concluded that not only is there no link between using cannabis and developing cancer, people who smoke cannabis are less likely to develop these lung problems than people who are non-smokers,” Tvert said.
