“For many years, the demonizing claims being made against cannabis have been crumbling as research slowly dispels them. Fifty years ago people earnestly believed that the consumption of cannabis was directly linked to the development of an array of mental illnesses, and violent and hypersexual behavior.”

 “Rewriting the medical records

The results of a new government-run research program are now forcing medical authorities to overturn these beliefs. The study has been ongoing for the past twenty years, following the smoking habits of over 5000 people.
 
 Researchers found that, contrary to popular belief, smoking cannabis, does not interfere with lung function or capacity. This holds true for ongoing regular -even including daily- and long term consumption.
 
 Curiously, as a general rule, cannabis smokers had better lung function than nonsmokers, which researchers attribute to the smoking action itself, rather than the cannabis. Pot smokers inhale deeply and hold those breaths to make the most of their supply, expanding the lung’s capacity.Dr. Tashkin found that, in almost all instances, cannabis consumers had rates of cancer that were no different from those who didn’t smoke cannabis. The one exception to this rule was between cannabis smokers and individuals who didn’t smoke anything (including tobacco), in which marijuana smokers actually had lower levels of lung cancer.”

“Regular cannabis smokers are no more likely to develop lung cancer than are people who indulge occasionally.

The finding of no significant increased risk held true whether the smokers imbibed once or twice – or more – each day, and regardless of how many years they had smoked, Dr. Li Rita Zhang reported at the annual meeting of the American Association of Cancer Research.

The study included data from six case-control studies conducted from 1999 to 2012 in the United States, Canada, the United Kingdom, and New Zealand, with a subject pool of 2,159 lung cancer cases and 2,985 controls. All of the studies were part of the International Lung Cancer Consortium (ILCCO), an international group of lung cancer researchers with the aim of sharing comparable data from ongoing and recently completed lung cancer studies from different geographical areas and ethnicities.

“OncologyPractice.com reports today that, “Regular cannabis smokers are no more likely to develop lung cancer than are people who indulge occasionally.” The cancer news site relates the findings of Dr. Li Rita Zhang reported at the annual meeting of the American Association of Cancer Research.”

 

““In an analysis of marijuana smokers that excluded tobacco smokers, there were no significant [cancer rate] differences in any of the comparisons, including habitual vs. nonhabitual use; number of joints smoked per day; duration of up to 20 years or duration of more than 20 years,” OncologyPractice reported.

The information fits in with prior assessments that marijuana smoking does not cause lung cancer.”

“In a recent presentation given at the annual meeting of the American Association of Cancer Research, investigators from the university of California, Los Angeles provided the latest data reaffirming that cannabis consumption is not associated with an elevated risk of lung cancer. Below is a summary of the findings from The Oncology Report:

The study included data from six case-control studies conducted from 1999 to 2012 in the United States, Canada, the United Kingdom, and New Zealand, with a subject pool of 2,159 lung cancer cases and 2,985 controls. All of the studies were part of the International Lung Cancer Consortium (ILCCO), an international group of lung cancer researchers with the aim of sharing comparable data from ongoing and recently completed lung cancer studies from different geographical areas and ethnicities.

Dr. Zhang of the University of California, Los Angeles, performed two analyses. One compared all lung cancer cases and all controls, regardless of concurrent or past tobacco use. Then, to reduce confounding by tobacco, she restricted the analysis to those who had never smoked tobacco.

… When compared with cannabis smokers who also used tobacco, habitual pot smokers had no significant increase in cancer risk. In an analysis of marijuana smokers that excluded tobacco smokers, there were no significant differences in any of the comparisons, including habitual vs. nonhabitual use; number of joints smoked per day; duration of up to 20 years or duration of more than 20 years.

The abstract of the presentation, which concludes “Our pooled results showed no significant association between the intensity, duration, or cumulative consumption of cannabis smoke and the risk of lung cancer overall or in never smokers,” is available online here.

Numerous preclinical studies have documented that cannabinoids possess potent anti-cancer properties, including the inhibition of lung cancer cell growth.”

Fighting Cancer: Another Study Reveals the Cannabis and Cancer Prevention Link

“Does marijuana cause cancer? Revealing the link between cannabis and cancer yet again, researchers with the California Pacific Medical Center in San Francisco have released findings that further bolster cannabis as an anti-cancer solution.
The researchers have found a compound in the much-talked-about plant could “halt the spread” of many types of aggressive cancers, including breast cancer.

The Cannabis and Cancer Link

Cannabidiol is the compound, and while it fights cancer cells, it does not produce the high feelings commonly associated with cannabis. Instead, it seems to “switch off” the gene responsible for metastasizing breast cancer.

They reportedly found the compound doesn’t only stop the breast cancer cells from growing, but even causes them to return back to normal cells, cancer-free.”

Smoking Marijuana Does Not Cause Lung Cancer

“New research shows here seems to be something in pot that actually undermines cancer, instead of causing it. — and the media are doing their best to ignore it.
 
There is a groundswell of attention in the news to marijuana’s role in causing and preventing various types of cancers. Last week, AlterNet published an article from the Marijuana Policy Project about a new study finding that pot smokers have a lower risk of head and neck cancers than people who don’t smoke pot…
 
Smoking pot doesn’t cause lung cancer. In fact, the study found that cigarette smokers who also smoked marijuana were at a lower risk of contracting lung cancer than tobacco-only smokers…
 

You’d think it would have been very big news in June 2005 when UCLA medical school professor Donald Tashkin reported that components of marijuana smoke somehow prevent them from becoming malignant.

 In other words, something in marijuana exerts an anti-cancer effect!”

Marijuana Unlikely to Cause Head, Neck, or Lung Cancer – WebMD

“Marijuana, unlike tobacco and alcohol, does not appear to cause head, neck, or lung cancer, says a researcher from Johns Hopkins Medical School in Baltimore who presented findings from a study here recently at a meeting of internal medicine physicians.

There has been an ongoing debate about whether marijuana is as dangerous as tobacco in terms of cancer development. Daniel E. Ford, MD, tried to sort out the evidence by the lifestyles — including marijuana, tobacco, and alcohol use — of 164 persons who were newly diagnosed with head, neck, or lung cancer compared to a group of 526 healthy persons living in the same area. The average age of patients was 49, while the average age of the healthy volunteers was 44. The cancer patients were all treated at four Baltimore-area hospitals, and the “controls” (healthy comparison group) were selected from a large group of people living in the Baltimore area who had been participating in an ongoing study. Ford tells WebMD that he wanted to find out whether the cancer patients were more likely to smoke marijuana or tobacco or to drink than were the healthy volunteers.

According to Ford, he thought he would find an association between marijuana use and cancer, but “that the association would fall away when we corrected for tobacco use. That was not the case. The association was never there.” And that surprised him because of the way marijuana is smoked: deep inhalations, with the smoke held in for effect. “It seemed natural that there would be some connection,” he tells WebMD.

Based on these findings, Ford says that cancer prevention efforts should “remain focused on tobacco and alcohol, two known carcinogens.””

Update from WebMD:

“Pot Smoking Not Linked to Lung Cancer

Study Shows No Increased Risk for Even the Heaviest Marijuana Smokers.
 
People who smoke marijuana do not appear to be at increased risk for developing lung cancer, new research suggests.While a clear increase in cancercancer risk was seen among cigarette smokers in the study, no such association was seen for regular cannabis users.Even very heavy, long-term marijuana users who had smoked more than 22,000 joints over a lifetime seemed to have no greater risk than infrequent marijuana users or nonusers.”

Medical Marijuana Inc Announces Positive Developments in Recent Studies Using Cannabidiol (CBD) Compound; NBC News, ABC News and Huffington Post Report California Pacific Medical Center’s Findings That CBD Stops Metastasis in Aggressive Cancers – The Wall Street Journal

“Medical Marijuana Inc Announces Positive Developments in Recent Studies Using Cannabidiol (CBD) Compound; NBC News, ABC News and Huffington Post Report California Pacific Medical Center’s Findings That CBD Stops Metastasis in Aggressive Cancers

SAN DIEGO, May 28, 2013 (GLOBE NEWSWIRE) — Medical Marijuana Inc (OTC Pink:MJNA) is pleased to inform shareholders and the general public of recent developments in the research involving Cannabidiol (CBD) and other Phyto-cannabinoids.

The Following is taken from a Huffington Post interview with Dr. McAllister and Dr. Desprez:

A pair of scientists at California Pacific Medical Center in San Francisco has found that a compound derived from marijuana could stop metastasis in many kinds of aggressive cancer, potentially altering the fatality of the disease forever.

“It took us about 20 years of research to figure this out, but we are very excited,” said Pierre Desprez, one of the scientists behind the discovery, to The Huffington Post. “We want to get started with trials as soon as possible.”

The Daily Beast first reported on the finding, which has already undergone both laboratory and animal testing, and is awaiting permission for clinical trials in humans.

Desprez, a molecular biologist, spent decades studying ID-1, the gene that causes cancer to spread. Meanwhile, fellow researcher Sean McAllister was studying the effects of Cannabidiol, or CBD, a non-toxic, non-psychoactive chemical compound found in the cannabis plant. Finally, the pair collaborated, combining CBD and cells containing high levels of ID-1 in a petri dish.

“What we found was that his Cannabidiol could essentially ‘turn off’ the ID-1,” Desprez told HuffPost. The cells stopped spreading and returned to normal.

“We likely would not have found this on our own,” he added. “That’s why collaboration is so essential to scientific discovery.”

Desprez and McAllister first published a paper about the finding in 2007. Since then, their team has found that CBD works both in the lab and in animals. And now, they’ve found even more good news.

“We started by researching breast cancer,” said Desprez. “But now we’ve found that Cannabidiol works with many kinds of aggressive cancers–brain, prostate–any kind in which these high levels of ID-1 are present.”

Desprez hopes that clinical trials will begin immediately.

“We’ve found no toxicity in the animals we’ve tested, and Cannabidiol is already used in humans for a variety of other ailments,” he said. Indeed, the compound is used to relieve anxiety and nausea, and, since it is non-psychoactive, does not cause the “high” associated with THC.

While marijuana advocates will surely praise the discovery, Desprez explained that it’s not so easy as just lighting up.

“We used injections in the animal testing and are also testing pills,” he said. “But you could never get enough Cannabidiol for it to be effective just from smoking.”

Dr. McAllister & CBD Research

Dr. Sean McAllister says that he is ready to begin testing CBD on humans to evaluate anti-cancer properties. Dr. McAllister and colleague Pierre Desprez, PhD from California Pacific Medical Center have previously mentioned, “Cannabidiol offers hope of a non-toxic therapy that could treat aggressive forms of cancer without any of the painful side effects of chemotherapy.” “We found that this one compound, CBD, had a specific effect on metastatic cancer cells, very aggressive tumor cells. CBD in animal studies has been used to ‘switch off’ a specific gene regulator.” Dr. McAllister explains: “We find when you treat with CBD, you down regulate the expression of this protein and that inhibits the disease process.” Dr. McAllister and Dr. Desprez have developed a synthetic version of CBD, which they say targets a specific gene in the body related to the spread of cancer (metastasis).

Marijuana mouth spray for cancer patients tough to abuse – NBC

“The medical marijuana drug Sativex, which could be approved in the United States in the coming years as a treatment for pain relief, has little potential for abuse, experts say.

The British pharmaceutical company GW Pharmaceuticals is currently testing the drug, which is delivered as a mouth spray and called Sativex, in clinical trials. The company plans to seek U.S. Food and Drug Administration approval for the drug as a treatment for cancer pain when the trials are completed, likely sometime in 2014, a spokesperson for GW Pharmaceuticals told MyHealthNewsDaily.

The active ingredients in Sativex, known as cannabinoids, are derived from the cannabis plant. It is the first marijuana-based drug to be made by extracting the compounds from the plant, rather than synthesizing them. Two other drugs, Marinol and Cesamet, based on synthetic cannabinoids, were approved by the FDA in the 1980s.”
