Study finds no marijuana-lung cancer link

LOS ANGELES, California (Reuters) -- Marijuana smoking does not increase a person's risk of developing lung cancer, according to the findings of a new study at the University of California Los Angeles that surprised even the researchers.
They had expected to find that a history of heavy marijuana use, like cigarette smoking, would increase the risk of cancer.
Instead, the study, which compared the lifestyles of 611 Los Angeles County lung cancer patients and 601 patients with head and neck cancers with those of 1,040 people without cancer, found no elevated cancer risk for even the heaviest pot smokers. It did find a 20-fold increased risk of lung cancer in people who smoked two or more packs of cigarettes a day.
The study results were presented in San Diego Tuesday at a meeting of the American Thoracic Society.
The study was confined to people under age 60 since baby boomers were the most likely age group to have long-term exposure to marijuana, said Dr. Donald Tashkin, senior researcher and professor at the UCLA School of Medicine.
The results should not be taken as a blank check to smoke pot, which has been associated with problems including cognitive impairment and chronic bronchitis, said Dr. John Hansen-Flaschen, chief of pulmonary and critical care at the University of Pennsylvania Health System in Philadelphia. He was not involved in the study.
Previous studies showed marijuana tar contained about 50 percent more of the chemicals linked to lung cancer, compared with tobacco tar, Tashkin said. In addition, smoking a marijuana joint deposits four times more tar in the lungs than smoking an equivalent amount of tobacco.
"Marijuana is packed more loosely than tobacco, so there's less filtration through the rod of the cigarette, so more particles will be inhaled," Tashkin said in a statement. "And marijuana smokers typically smoke differently than tobacco smokers -- they hold their breath about four times longer, allowing more time for extra fine particles to deposit in the lung."
He theorized that tetrahydrocannabinol, or THC, a chemical in marijuana smoke that produces its psychotropic effect, may encourage aging, damaged cells to die off before they become cancerous.
Hansen-Flaschen also cautioned a cancer-marijuana link could emerge as baby boomers age and there may be smaller population groups, based on genetics or other factors, still at risk for marijuana-related cancers.

As much as I would love to believe that is true, I have a hard time believing that inhaling smoke of any kind does not increase the risk of cancer. Like I said, though, I would hope to the high heavens that I am wrong.

I feel fairly confident that you are wrong. You are correct in the sense that there is no such thing as healthy smoke. Anything one smokes is going to take it's toll on the body. But, just because something isn't healthy does not mean that it is cancerous. It is certainly feasable that one type of smoke may be more, or less, harmful than another. (If forced, I would much rather inhale smoke from burning wood than smoke from burning plastic, for example.)

I believe a study last year showed that marijuana smoke contains significant anti-inflammitory components that are not present in tobacco and this may even lower the risk of cancer in smokers who also smoke ganj.
The same protein that causes inflammation in response to irritation also prevents apoptosis in epithelial cells. I wouldn't be surprised if this is a major factor in most smoking-related cancers but that remains to be proven.
This is interesting because it might be possible to add trace amounts of anti inflammitory agents to commercially made cigarettes to lower cancer rates but it would have to be very benign so hardcore smokers don't OD.

The government has been preaching for years that marijuana doesnt have any medical value and it turns out to be the fuckn cure for cancer.

well studies have shown THC to have anti-tumur properties.
THC not smoke.
would be righteous if cannabis were a cancer cure though.
