“An Israeli researcher has found that tiny doses of the psychoactive chemical in marijuana helps the brain of mice combat injury.”
“The words “marijuana” and “brain damage” usually go in that order in medical literature. An Israeli researcher has flipped them around, finding that THC, the active ingredient in marijuana, may arrest some forms of brain damage in mice. The loco weed already is favored by those who suffer from chronic diseases, not to mention fans of Cypress Hill, Bob Marley and the Grateful Dead. But pharmacologist Josef Sarne of Tel Aviv University found that a minuscule amount of tetrahydrocannabinol may protect the brain after injuries from seizures, toxic drug exposure or a lack of oxygen.” |

Marijuana component can halt brain damage
“Extremely low doses of THC, the psychoactive component of marijuana, protects the brain from long-term cognitive damage in case of injury from hypoxia (lack of oxygen), seizures, or toxic drugs, a new study has claimed.
Medical cannabis is often used by sufferers of chronic ailments, including cancer and post-traumatic stress disorder, to combat pain, insomnia, lack of appetite, and other symptoms.
Now, Professor Yosef Sarne of Tel Aviv University’s Adelson Center for the Biology of Addictive Diseases at the Sackler Faculty of Medicine in US found the drug has neuroprotective qualities as well.
Previous studies focused on injecting high doses of THC within a very short time frame approximately 30 minutes before or after injury.
Sarne’s current research, published in the journals Behavioural Brain Research and Experimental Brain Research, demonstrates that even extremely low doses of THC around 1,000 to 10,000 times less than that in a conventional marijuana cigarette administered over a wide window of 1 to 7 days before or 1 to 3 days after injury can jump start biochemical processes which protect brain cells and preserve cognitive function over time.
This treatment, especially in light of the long time frame for administration and the low dosage, could be applicable to many cases of brain injury and be safer over time, Sarne said.
While performing experiments on the biology of cannabis, researchers found that low doses of the drug had a big impact on cell signalling, preventing cell death and promoting growth factors.
This finding led to a series of experiments designed to test the neuroprotective ability of THC in response to various brain injuries.
In the lab, the researchers injected mice with a single low dose of THC either before or after exposing them to brain trauma. A control group of mice sustained brain injury but did not receive the THC treatment.”

Low doses of marijuana component can protect brain against injury
“Though marijuana is a well-known recreational drug, extensive scientific research has been conducted on the therapeutic properties of marijuana in the last decade. Medical cannabis is often used by sufferers of chronic ailments, including cancer and post-traumatic stress disorder, to combat pain, insomnia, lack of appetite, and other symptoms.
Now Prof. Yosef Sarne of Tel Aviv University’s Adelson Center for the Biology of Addictive Diseases at the Sackler Faculty of Medicine says that the drug has neuroprotective qualities as well. He has found that extremely low doses of THC—the psychoactive component of marijuana—protects the brain from long-term cognitive damage in the wake of injury from hypoxia (lack of oxygen), seizures, or toxic drugs. Brain damage can have consequences ranging from mild cognitive deficits to severe neurological damage.
Previous studies focused on injecting high doses of THC within a very short time frame—approximately 30 minutes—before or after injury. Prof. Sarne’s current research, published in the journals Behavioural Brain Research and Experimental Brain Research, demonstrates that even extremely low doses of THC—around 1,000 to 10,000 times less than that in a conventional marijuana cigarette—administered over a wide window of 1 to 7 days before or 1 to 3 days after injury can jumpstart biochemical processes which protect brain cells and preserve cognitive function over time.

“Miracle” Cannabis Oil: May Treat Cancer, But Money and the Law Stand in the Way of Finding Out
“First it was a cough. Then it was bronchitis. Then it was time to say goodbye to Michelle Aldrich.
The year 2011 was supposed to be a good one for the 66-year-old. That June, she and her husband, Michael, were feted with a lifetime achievement award by High Times magazine for their four decades of work on marijuana legalization. Yet something was off. She was smoking a lot, maybe more than ever.
And she couldn’t get high.
In the fall of that year — a bad time for the local marijuana movement, as the federal Justice Department began shutting down hundreds of California medical cannabis dispensaries — Aldrich went in to see a series of doctors for what she thought was a flu that just refused to go away.
After six weeks of progressively worse diagnoses — flu became bronchitis, which became pneumonia — a CT scan revealed the cause behind the “heat” she felt in the middle of her chest. A tumor, “poorly-differentiated non-small cell adenocarcinoma.” In other words, stage 3 lung cancer.
Lung cancer is a killer, with nearly 70 percent of new cases resulting in deaths, according to statistics published by the National Cancer Institute. “I thought I was going to die,” Aldrich says from her Marina District apartment. But she didn’t. And now, she is busy telling anyone who will listen that, along with diet and chemotherapy, a concoction of highly concentrated cannabis oil eliminated her cancer in less than four months.”

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

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.”
