That study wasn't propaganda-motivated. I was able to look at it in detail today in our med school library. It was by medical scientists and was a fair sampling, not supported by any funds from anti-drug or pharmaceutical companies. Just pure research. It's just that it was a very different and much smaller evaluation group than other studies that have been done. It certainly showed diametrically opposite findings from what the larger Tashkin/UCLA studies have reflected.

What does it mean? It means the same thing we've always known, particularly since studies have a history of conflicting on this subject. I means you need to be aware that there may indeed be some risk for very heavy smokers. And it means we need more far-reaching human studies to see if there's a consistent conclusion that can be drawn.

I have known two people who were cigarette-level cannabis smokers. In other words, they smoked very heavily, many many joints a day. Both of those were middle-aged men. Both have now died of lung cancer. They never smoked cigarettes, either of them. Maybe it was genetic. Maybe it was from environmental exposure earlier in their childhoods. But it certainly made those who'd known of their heavy cannabis histories wonder. We have a nation of 14 million cannabis smokers here in America, probably many many more, but since it's an illicit substance for the most part, we have no way of getting a more accurate count. That's a lot of folks, and anyone who believes some percentage of those folks hasn't had at least some cancers or health-related negative consequences doesn't really have an accurate view of statistical morbidity and mortality. You can bet it's certain that in a group that big, someone has died, whether it's from heavy cannabis smoking and cancer. From heavy smoking and heart disease. From heavy smoking and respiratory failure. Since cannabis use is mostly illicit, though, we don't see cannabis morbidity/mortality reported like we do other diseases.

Do they mean tobacco before or after all the harmful chemicals have been added by the tobacco industry?

I don't put to much faith in lab animal testing. Seems that white mice get cancer off of everything that we enjoy.

Have a good one!:jointsmile:

If they could show me a single case of somebody smoking only marijuana and getting lung cancer, I might be inclined to believe them. However, all I see is 400,000 deaths a year from cigarettes, and not one from the good herb. It sounds like propaganda to me.

I have never known a single person that got cancer from weed. A lot of people are smoking because of cancer not because of pot.

[Innominate]

Simply not true.

As far as I know ... the largest case study done regarding this issue was in 2006.

Study Finds No Cancer-Marijuana Connection - washingtonpost.com

Research showed no proof of marijuana use directly effecting lung cancer rates ... but a 20x risk for those who smoke 2-3 packs of cigs a day.

Cannabis can be used in food, resin pills, and vaporized anyways .....

I wish everybody was aware, though, that the majority of cancer risk in tobacco doesn't even come from the carcinogens, but from Polonium-215 present in the soil they grow the tobacco in; and thus retained in the plant itself.


Funny how these objective anti-cannabis sites, giving us all the "facts", keep out facts like that; or the fact that cannabinoids selectively and aggresively destroy cancer cells. Not to mention acting neuro-protectively against physical head trauma and mutagenic agents.
