Marijuana Causes Cancer?

Office of Environmental Health Hazard Assessment
Prop 65 Implementation

1001 I St., 19th Floor
Sacramento CA 95812-4010 We are responding to OEHHA's request for scientific information regarding the carcinogenicity of marijuana smoke for hearings by the Carcinogen Identification Committee on November 19, 2007. The best current evidence is that marijuana smoke does not cause cancer. Even though it can contain various carcinogenic pyrolytic compounds similar to those found in tobacco smoke, the best epidemiological studies have failed to detect elevated cancer rates in marijuana smokers. One possible explanation is that the major psychoactive ingredient of marijuana, delta-9-tetrahydrocannabinol (THC) has anti-carcinogenic properties, whereas the major ingredient of tobacco, nicotine, is cancer promoting [Melamede[1]].

say you had two groups: one group who ate burnt steak, and another group who ate burnt steak while drinking green tea. the group who drank the green tea would probably develop fewer cancers. It might even mitigate the statistical increase of the burnt steak to begin with. that is the affect we are seeing when we analyze marijuana smoke vs tobacco smoke. Even if THC/CBD are healthy, the other constituents of "smoke" (burnt plant matter) are NOT healthy.

@Gfrant this comment is making the point the video intended to point out. and no where does it claim that smoking any burning plant matter can't cause harm. but studies point out exactly what your analogy does...if a person smokes pot or pot and ciggs, there do seem to be lower chances of certain cancers over those who just smokes ciggs. the 'pot' is your green tea....pot does not increase most cancers it does seem to decrease...

Smoking anything causes a variety of health problems, if you dry out a fucking apple and smoke it regularly you can in fact develop CANCER. Im not hating, just be aware, and dont go around saying smoking anything is good.

@dmorris41 sighhh

Hear's the truth, if you go into the hospital and you are a smoker. They give you a pamphlet that tells you all these facts about cigerette smoke. Here's the problem, it says 10 minutes after your last cigerette your lungs start repairing themselves. one night I smoke almost 8 joints my lungs were effected I found it didn't stay that way for even ten minutes.

@joere444 that does not surprise me at all!

This is not to say that Marijuana doesn't have potentially beneficial properties. If you want to harness them, make an extract or cook with it. Perhaps even vape. Find a way to use it therapeutically without generating carcinogens. Marijuana doesn't cause cancer--combustion byproducts of plant matter does. Green tea might be healthy as a tea, but if you were to smoke it, you would generate carcinogens.

@EssiacHempLaetrile technically 125 reasons that were drug up because origionally they didnt have proof so yeah.

[NC420Reform]

@merolhed but they have done studies that show it can kill cancer cells too. I am not familiar with dysplasia and will do some research.

[merolhed]

but the products created by the combustion of the elements of the plant may cause irritation of the respiratory tract epithelium which is a cause of metaplasia that can develop dysplasia, and then malignant neoplasia. It doesn't happen always but there's a big chance that marijuana smokers can develop cancer in a long term. Sorry, my English sux
