What Smoking Marijuana Does To Your Lungs






Given that smoking cigarettes causes cancer, cannabis smoking should as well? Incorrect.

Cannabis lowers the risk of lung cancer. Cannabis does not create chronic obstructive lung illness (COPD). Therefore, cannabis is much safer than cigarettes.

Professor emeritus of medicine at UCLA as well as one the United States' leading pulmonologists who has been studying Cannabis as well as its impacts on lungs for longer than 30 years, Dr. Donald Tashkin once looked for to prove cannabis causes lung cancer cells, yet the evidence compelled him to conclude that ordinary cannabis smoking does not create lung cancer or harm 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.”



Dr. Tashkin is not the only one in his analysis. To look into the organization in between cannabis smoking and lung cancer threat, information on 2,159 lung cancer cases and also 2,985 controls were pooled from 6 case-control research studies in the US, Canada, UK, as well as New Zealand within the International Lung Cancer cells Consortium. Results from the pooled analyses in 2014 given little proof for an increased threat of lung cancer amongst regular or long-term marijuana smokers.

“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



Dr. Tashkin discovered that smoking marijuana, unlike smoking tobacco, does not cause COPD.

“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 findings from a previous study. In a large cross-sectional evaluation people adults aged 18 to 59 utilizing information from two rounds of the National Health as well as Nutrition Examination Studies (NHANES), scientists from Georgia's Emory University found in 2015 that low as well as cumultive cannabis usage was not related to negative effects on lung function.





Cumulative lifetime marijuana usage, as high as 20 joint-years, is not connected with negative changes in spirometric [an individual's capacity to exhale] procedures of lung wellness. Greater than 20 joint-years of cumulative cannabis exposure was linked with a twofold enhanced chances of a FEV1/FVC less than 70%, this was the result of a rise in FVC [ required vital capability], instead of a disproportional reduction in FEV1 [forced expiratory volume] as is normally connected with obstructive lung conditions.



The biggest as well as longest research study ever before to think about the concern [Researchers tested the lung function of 5115 young adults over the course of Twenty Years, beginning in 1985 when they were matured 18 to 30], published in 2012 in the Journal of the American Medical Association, found that occasional marijuana smoking does not hinder lung function.

Cannabis may have useful impacts on pain control, hunger, mood, and management of various other chronic signs and symptoms. Our searchings for suggest that periodic usage of marijuana for these or various other objectives may not be connected with damaging effects on lung function.

Cannabis plus cigarette equals lung poisonous substance

Consultant Physician at St. Lucia's Victoria Medical facility, Dr. Martin Didier, cautions:

“Tobacco contains over 4,000 toxic substances which destroys your lungs. Marijuana for all we know is less toxic, probably contains up to 400 but the combination of smoking marijuana and tobacco they interact and it changes the whole thing into a poison. A poison which destroys the structure and function of the lungs with a lot of consequences.”



Cannabis use alone does not cause considerable problems 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.”

Since cigarette smoking causes cancer cells, cannabis smoking should. Cannabis decreases the threat of lung cancer cells. Cannabis does not trigger persistent obstructive lung condition (COPD). To investigate the association in between marijuana cigarette smoking as well as lung cancer risk, data on 2,159 lung cancer cells situations as well as 2,985 controls were merged from 6 case-control researches in the US, Canada, UK, and also New Zealand within the International Lung Cancer cells Consortium., released in 2012 in the Journal of the American Medical Organization, knew that periodic marijuana cigarette smoking does not impair lung function.
