Since they say tobacco causes cancer, you would think smoking marijuana would as well… Right? Wrong!?
Marijuana decreases the risk of lung cancer. Marijuana does not cause chronic obstructive pulmonary disease (COPD). Thus, Pot is safer than cigarettes.
Professor emeritus of medicine at UCLA and one of the United States’ leading pulmonologists who has been studying weed and its effects on lungs for more than 30 years, Dr. Donald Tashkin once sought to prove pot causes lung cancer, but the evidence forced him to conclude that average weed smoking does not cause lung cancer or impair lung function:
“The smoke content of marijuana is very similar to that of tobacco. There is a higher concentrate of cancer-causing chemicals in marijuana tar, and it reaches the lungs before any other organ, so there is this idea that they are related in causing the same health issues of the lungs. But through my studies we failed to find any positive association [with cancer]. Instead, the association would be negative, between lung cancer and the use of marijuana. The likelihood is, that despite the fact that marijuana smoke contains carcinogens, we don’t see the same heightened risks of cancers that we see in tobacco.”
“I was opposed to legalization because I thought it would lead to increased use and that would lead to increased health effects. But at this point, I’d be in favor of legalization. I wouldn’t encourage anybody to smoke any substances. But I don’t think it should be stigmatized as an illegal substance. Tobacco smoking causes far more harm. And in terms of an intoxicant, alcohol causes far more harm.” – Dr. Tashkin
“Reasoning for this may be that marijuana is a potent anti-inflammatory and suppressive. But COPD is activated by tobacco smoke and other toxic substances. The other major impact of tobacco smoking on the lungs is the association between smoking tobacco and the development of destructive pulmonary disease, the third cause of death in America.”
Again, his current findings echo results from previous research. In a large cross-sectional analysis of US adults aged 18 to 59 using data from two rounds of the National Health and Nutrition Examination Surveys (NHANES), researchers from Georgia’s Emory University found in 2015 that occasional and low cumulative marijuana use was not associated with adverse effects on pulmonary function.
The largest and longest study ever to consider the issue [Researchers tested the lung function of 5115 young adults over the course of 20 years, starting in 1985 when they were aged 18 to 30], published in 2012 in the Journal of the American Medical Association, found that occasional marijuana smoking does not impair lung function.
Marijuana use alone doesn’t cause significant abnormalities to the lungs
Allen St. Pierre, executive director of the National Organization to Reform Marijuana Laws, told ThinkProgress:
“If we’re serious public policy people, we would let the scientists figure this out. Does one set of vegetative matter produce a certain range of carcinogens? If so, to what degree and amount? How do people consume it? This entire discussion should be based on science. But the laughable thing is that the government is against this type of research. All we have are anecdotes but we need science that meets the standards of a proper peer review.”
