Researchers say Marijuana Smoking Not Linked To Cancer or Lung Damage

Donald Tashkin's is a tale cannabis pushers like to repeat. The physician and professor at UCLA's David Geffen School of Medicine set out to prove -- via a study funded by the National Institutes on Drug Abuse -- that marijuana is bad for you. Instead, a long-term study found no solid link between marijuana use and lung cancer, in sharp contrast to tobacco terrible effects on health.
Similar findings were repeated all over the world. In a collection and review of studies on marijuana's effect on the lungs, published in the June issue of the Annals of the American Thoracic Society, Tashkin concludes that compared to tobacco smoking, heavy marijuana use has "relatively small and far lower" risks.
This despite an average joint marijuana having four times the tar of a typical American Spirit. How can this be?
It's worth remembering that this is not a new development -- Tashkin's long-term study was published in 2006. And well before that -- as in the 19th Century, when cannabis tinctures and other marijuana medicines were sold in pharmacies -- doctors were prescribing marijuana as a treatment for asthma patients.
There's more similarities between tobacco and marijuana that most cannabis advocates would like to admit. There are similar levels of ammonia and other carcinogens, and marijuana smokers inhale about four times the tar, Tashkin notes.
Yet several long-term studies found no positive association between marijuana use and lung cancer. And others -- judging lung function and health by lung capacity, function, and things like levels of sputum and phlegm -- found no positive link between marijuana use, even heavy, long-term use, and chronic obstructive pulmonary disease.
Marijuana use does have deleterious effects, but they are short-term. Other than bronchitis that goes away after the pipe is put away, it appears there's not much else long term harm done to the lungs by marijuana.
