People say there is no evidence that marijuana causes cancer. I don’t believe that for one split second.

Ok…is that all? You want to post any research to the contrary?

Is there any research that could back it up, that marijuana does in fact cause cancer?
 
How could it not? The smoke is just as carcinogenic as cigarettes, isn’t it?
 
not sure if this belongs in the moral theology forum…

Beats the heck out of me. You brought up the subject so I was hoping you had some research available.
 
MARIJUANA / CANCER LINK*Lung cancer causing carcinogen more prevalent in marijuana than in tobacco.*Sandra Bennett, Northwest Centre for Health & Safety.

A breakthrough report published in the journal Science, October 18, 1996,provides the first true molecular evidence conclusively linking components in tobacco smoking to lung cancer.

A chemical found in tobacco smoking, benzopyrene, causes genetic damage in lung cells that is identical to the damage observed in the DNA of most malignant tumors of the lungs. Although scientists have been convinced in the past that smoking causes lung cancer, the strong statistical associations did not provide absolute proof. This paper absolutely p(name removed by moderator)oints that mutations in lung cancer cells are caused by benzopyrene.

An average marijuana cigarette contains 30 nanograms of this carcinogen, compared to 21 nanograms in an average tobacco cigarette (Marijuana and Health, National Academy of Sciences, Institute of Medicine report,1982). This potent carcinogen suppresses a gene that controls growth of cells. When this gene is damaged, the body becomes more susceptible to cancer. This gene, P53, is related to half of all human cancers and as many as 70% of lung cancers.

Clearly marijuana smoke contains more of the potent carcinogen benzopyrene than tobacco smoke. Furthermore, the technique of\line smoking marijuana by inhaling deeply and holding the smoke within the lungs presents a chance of much greater exposure than a conventional tobacco cigarette. This material has been reviewed and commented on by William M. Bennett, M.D., Professor of Medicine, Division of Nephrology, Clinical Pharmacology and Hypertension at Oregon Health Sciences University, Portland, Oregon. Dr. Bennett, who is listed in “BEST DOCTORS IN AMERICA,” states, "The idea of using smoked marijuana containing these carcinogens as medicine, particularly for patients who have suppressed immune systems like those with AIDS, should be unthinkable. Thus, prior to considering marijuana as medicine, one must abide by the old edict, “first do no harm.”}

**Maybe this answers your question.

Not really, because it’s a 9 year old article. Got anything recent? Multiple studies would be nice as well.
 
Recent research and trends

. White or red patches in the mouth of a marijuana smoker may indicate oral or tongue, cancer. About half the people who get tongue cancer die within five years. Incidence of tongue cancer among people under 40 has gone up over 60 percent in the past two decades. Marijuana use by the young is suspected by researchers to be a source of these trends. One marijuana joint is as potent with cancer-agents-including carbon monoxide-as five tobacco cigarettes.
  • Among illicit drugs, only cocaine will land a person in the emergency room more often than marijuana-29 percent of episodes involve cocaine vs. 16 percent with marijuana.
Sources:www.forreal.org; A Summary of Findings from the 2001 National Household Survey on Drug Abuse, SAMHSA, 2002; Overview of the Key Findings, Monitoring the Future 2001, National Institutes of Health, 2002; Marijuana, Substance Abuse Resource Guide, SAMHSA, 2000; Emergency Department Trends from the DAWN, Preliminary Estimates, 2001, SAMHSA, Office of Applied Studies, 2002; Marijuana: Weeding Out the Hype!, SAMHSA, 2002.
 
If you do enough of anything you will get cancer and while marijuana can certainly fall in this category, I don’t suspect there are that many cases of it because people just dose up on the THC and stop. If they chain-smoked joints all day you would see more instances of cancer probably.

Thanks. Here’s another one. Someone tried to convince me that marijuana doesn’t stay in your body for months. I say that because he said that he had friends who took marijuana and he claimed his friends said it wasn’t true. I don’t believe that and refuse to.

Good thing you don’t work on an oncology unit like my spouse does. Here’s a delightful picture of what tongue cancer looks like. Keep rationalizing why one must use marijuana. Maybe you will convince yourself. You won’t ever convince me.

Bob Marley didn’t believe there was a link either 😉

Yes, but if they only have two years to live anyway. Who cares if they get cancer twenty years down the road.

And if we went by the edict “do no harm” most prescription drugs would be eliminated. It is a matter of weighing the risks vs. the benefits.
 
I think that the Government’s drive to recognize the use of majiruana is no more than an attempt to legetimize it. If becomes permissive for the sick then I guess we are to some degree sick. Today in America we have hundreds of other palliatives that are legal to use than marijuana, which is an introductory drug to stronger drugs. As little comfort the drug gives, I would never use it for medicinal use, let alone heart operation. In doing so, one would be doing an unholy act.
