The aim of the present study was to determine the risk of lung cancer associated with cannabis smoking.
A case–control study of lung cancer in adults ≤55 yrs of age was conducted in eight district health boards in New Zealand. Cases were identified from the New Zealand Cancer Registry and hospital databases. Controls were randomly selected from the electoral roll, with frequency matching to cases in 5-yr age groups and district health boards. Interviewer-administered questionnaires were used to assess possible risk factors, including cannabis use. The relative risk of lung cancer associated with cannabis smoking was estimated by logistic regression.
In total, 79 cases of lung cancer and 324 controls were included in the study. The risk of lung cancer increased 8% (95% confidence interval (CI) 2–15) for each joint-yr of cannabis smoking, after adjustment for confounding variables including cigarette smoking, and 7% (95% CI 5–9) for each pack-yr of cigarette smoking, after adjustment for confounding variables including cannabis smoking. The highest tertile of cannabis use was associated with an increased risk of lung cancer (relative risk 5.7 (95% CI 1.5–21.6)), after adjustment for confounding variables including cigarette smoking.
In conclusion, the results of the present study indicate that long-term cannabis use increases the risk of lung cancer in young adults.[/quote:l719lodd]

Of course if I was that concerned about getting lung cancer I'd stop smoking altogether - cigarettes as well - and buy a vaporizer.
They say that breathing LA air is the equivalent of smoking a half pack of cigarettes a day.
I'm not calling anyone out here.

Without reading the report, is it safe to assume the increase shown in the study for pot smokers wasn't necessarilly the only type of smoke inhaled by the group? Or were those people ONLY pot smokers? If so, an argument coud be made then that the results aren't conclusive as to just pot.[/quote:2o98h62p]
The quote you picked up on is from a marijuana.com "myth" page. That's their statement.
The New Zealand study actually was able to control for cigarette smoking and was able to determine risk rates for marijuana-only, cigarette-only, and combined marijuana and cigarette smoking separately. Even in marijuana-only, the risk is increased 5.7%.
Everyone knows of someone who died in a car crash and wasn't drinking...does that make it ok to drink and drive?
I didn't realize so many C-level managers and entrepreneurs smoked weed, either, until recently. Once I got into project management, I started working around these people, and I've come to find out more smoke pot than those who don't...by far.
You shouldn't be surprised. About 1/3 of the US population has smoked pot. Considering the demographics here, the number on MD is much higher than that.
