Marijuana May Fight Lung Tumors

Cannabis may be bad for the lungs, but the active ingredient in marijuana may help combat lung cancer, new research suggests.

In lab and mouse studies, the compound, known as THC, cut lung tumor growth in half and helped prevent the cancer from spreading, says Anju Preet, PhD, a Harvard University researcher in Boston who tested the chemical.

While a lot more work needs to be done, the results suggest THC has therapeutic potential, she tells WebMD.

Moreover, other early research suggests the cannabis compound could help fight brain, prostate, and skin cancers as well, Preet says.

The findings were presented at the annual meeting of the American Association for Cancer Research.

The finding builds on the recent discovery of the body's own cannabinoid system, Preet says. Known as endocannabinoids, the natural cannabinoids stimulate appetite and control pain and inflammation.

THC seeks out, attaches to, and activates two specific endocannabinoids that are present in high amounts on lung cancer cells, Preet says. This revs up their natural anti-inflammatory properties. Inflammation can promote the growth and spread of cancer.

In the new study, the researchers first demonstrated that THC inhibited the growth and spread of cells from two different lung cancer cell lines and from patient lung tumors. Then, they injected THC into mice that had been implanted with human lung cancer cells. After three weeks, tumors shrank by about 50 percent, compared with tumors in untreated mice.

Preet notes that animals injected with THC seem to get high, showing signs of clumsiness and getting the munchies. You would expect to see the same thing in humans, so if this work does pan out, getting the dose right is going to be all important, she says.

Paul B. Fisher, PhD, a professor of clinical pathology at Columbia University, says that though the work is interesting, it's still very early.

The issue with using a drug of this type becomes the window of
concentration that will be effective. Can you physiologically achieve what you want without causing unwanted effects, he tells WebMD.

Want to lean the facts about medical cannabis? Why there is no such thing as "recreational use"? Why ALL use is medical?

I have an odd hobby, I collect medical studies and articles on cannabis. Want to read the real thing, not some 3rd hand story about the facts? My collection is available on line here-

http://www.greenpassion.org/showthread.php?t=20828

Why not get the actual medical facts for a change, instead of rehashed propaganda dating from 1937!

Cannabis has been shown to be useful in treating cancers, MS, diabetes, high blood pressure, fibro, motion sickness, GERD, Crohn's, IBS, epilepsy, nausea, osteoporosis, spasicity, dystonia and much more! From trivia conditions like the hiccups, to deadly serious ones like breast cancer, cannabis can treat them! But DON'T believe me! Look at the studies! Educate yourself!

To give you a preview of my list, here are a few WebMD articles I pulled just to give you a taste of what's in my list-

It's funny that they're calling this "new" research when studies have been showing that THC and the like fight cancer since 1974.

There's nothing new about this.

clevercandi, the reason bottled water is marketed is because it can just be bottled and sold. It doesnt need to be patented. The patent laws for medicinal compounds and research state that natural compounds cannot be patented, and only reason researchers patent a compound is to make money, because whenever another researcher uses the patented compound they have to pay for the licensure. Thus, it's just not economical to funnel the hundreds of millions of dollars necessary into a compound you cannot even make a return off of. Water is marketed to the consumer, and we dont pay licensure to drink it.

Congress should take a history lesson from the Prohibition. They're inhibiting a substance that is addictive and can be dangerous, but the demand is there and so there will always be a supplier. Prohibition was ended during the Depression so that there would be jobs and the government could tax the breweries, among other things. Congress imposes taxes on ciggs and booze even tho -how- many people are killed each year as direct result of either product. It's foolish to keep trying to fight the country. And if weed is legalized, the govt can regulate it and drug cartels would have a leg cut from beneath them.

as for the idea that potheads are bad, etc. Queen Victoria, the Prude with a P, smoked weed regularly for medicinal purposes.

Isn't it interesting that every post on this string is for legalizing marijuana, and yet we allow our government to spend billions of dollars keeping illegal. The damage the drug war has done to our country is beyond description. Check out DRCnet's website and volunteer or send money.

I wish I had know of this study when my mother had surgery for lung cancer which eventually killed her. Perhaps she would have lived a few more years if the study is correct. I know I would have done what I could to have ensured that she had a pain free life after the surgery which was not the case.

Well, too bad for anyone suffering from lung cancer. Marijuana is BAD BAD BAD, much worse than cancer any day. At least that's what the Feds would have us believe.

&quot;Groovy......was this study funded by &quot;High Times&quot; or &quot;Rolling Stone&quot;?&quot;
No infidel, but you've already demonstrated your taste for propaganda. If it isn't funded by FOX news, you're not buying...
