“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 Univ.’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. 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 one to seven days before or one to three days after injury can jumpstart 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 says.”

Is marijuana bad for you?

“Hasn’t pot always been considered harmful?
Not at all. Marijuana, the dried form of the plant Cannabis sativa, was used as an herbal remedy for centuries in China, the Middle East, and Asia. William O’Shaughnessy, a physician for the East India Tea Company, brought it west in the 1830s as a treatment for rheumatism, tetanus, and rabies. It was commonly prescribed as a pain reliever in the U.S. until the 1930s, when its growing popularity caused such concern that the newly founded Federal Bureau of Narcotics reclassified it as a narcotic. The bureau soon launched a decidedly unscientific campaign claiming that marijuana use provoked insanity, homicidal tendencies, and uncontrollable lust. The marijuana user, the bureau asserted, “becomes a fiend with savage or ‘caveman’ tendencies. His sex desires are aroused, and some of the most horrible crimes result.””

Adolescents who smoked marijuana at least four times a week, lost an average of 8 IQ points between the ages of 13 and 38, according to a study from New Zealand.

“Was there any evidence for such claims?
None; in fact, the American Medical Association argued against marijuana prohibition in the 1930s, citing its therapeutic potential. But the bureau made its case that marijuana was “dangerous for the mind and the body,” and the federal government outlawed its use in 1937. It wasn’t until the 1970s that a campaign began to restore marijuana’s therapeutic reputation, and in 1996 California became the first state to legalize cannabis for medicinal purposes. Psychiatrist Tod Mikuriya, a founding father in the medical marijuana movement, claimed that cannabis has none of the adverse side effects of opiates. “In fact,” he said, “it really enhances both quality of life and rehabilitation.””

“Drawing upon data from 13 states from 1993 – 2009, professors from Montana State University, the University of Oregon and the University of Colorado Denver found that medical marijuana actually had a negative impact on the consumption of cocaine, the use of which declined 1.9 percent in areas that had legalized medical marijuana. It had no statistically significant impact on teen marijuana use.”

Marijuana Vaporizer Provides Same Level Of THC, Fewer Toxins, Study Shows

“A smokeless cannabis-vaporizing device delivers the same level of active therapeutic chemical and produces the same biological effect as smoking cannabis…

…smoked cannabis can alleviate the chronic pain caused by HIV-related neuropathy, but a concern was expressed that smoking cannabis was not safe. This study demonstrates an alternative method that gives patients the same effects and allows controlled dosing but without inhalation of the toxic products in smoke,” said study lead author Donald I. Abrams, MD, UCSF professor of clinical medicine.

…pills tend to provide patients with more THC than they need for optimal therapeutic effect and increase side effects.

Patients rated the “high” they experienced from both smoking and vaporization and there was no difference between the two methods by patient self-report of the effect, according to study findings. In addition, patients were asked which method they preferred.

“By a significant majority, patients preferred vaporization to smoking, choosing the route of delivery with the fewest side effects and greatest efficiency,” said Benowitz.”

Bogarting that joint might decrease oral hpv among cannabis users

“The development of oral cancer is not a result of smoking cannabis per se; rather, it is hypothesized to be a result of contracting hpv through various forms of sharing and passing joints and other smoking apparatuses. Therefore, it is hypothesized that bogarting (and not passing) joints might decrease oral hpv among cannabis smokers.

It certainly may not be the cannabis smoke that causes oral cancers in heavy cannabis users. Most people who have ever smoked cannabis have most likely done so by sharing a rolled cigarette or pipe in a group setting. The sharing and passing of these smoking devices from an oral hpv-infected individual to an uninfected individual could easily provide a route of transmission for the virus between users. Frequency and setting should therefore be considered two major factors that might contribute to the likelihood of acquiring oral hpv.

Thus, the relationship between cannabis and various cancer types might not be from cannabis use itself, but rather from contracting high-risk types of oral hpv that lead to cancer in later life.”

“Miracle” Cannabis Oil: May Treat Cancer, But Money and the Law Stand in the Way of Finding Out

“Cannabis oil, which cancer-sufferers credit with saving their lives, and which is supposedly useful in healing other ailments, from diabetes to skin rashes, is made by distilling raw bud down to its essential ingredients.”

“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.”

“Oral cancer represents 3% of all cancers and its overall survival rate of 50% places it among the worst of all cancers

For many years cannabinoids have been used for medicinal and recreational purposes.

Recently, studies have focused on the therapeutic effects of cannabinoids on different cancers. The current study was the first to investigate the therapeutic effects of synthetic cannabinoids on oral cancer.

We investigated the effects of cannabinoid receptor agonists on (1) oral cancer cell viability in vitro and (2) oral cancer pain and tumor growth in a mouse cancer model.

Here we demonstrate the anti-nociceptive and anti-proliferative effects of systemic administration of cannabinoid receptor agonists on human oral cancer cells.

Our results suggest that systemic administration of cannabinoids decease oral cancer pain.

Our findings suggest a direct role for cannabinoid mechanisms in oral cancer pain and proliferation.

The systemic administration of cannabinoid receptor agonists may have important therapeutic implications wherein cannabinoid receptor agonists may reduce morbidity and mortality of oral cancer.

The present findings suggest that cannabinoid treatment may be a promising alternative therapy for oral cancer pain management. Furthermore, CBr2 agonism is not only palliative, but it may also be effective in inhibiting oral cancer growth, making the agonist a particularly desirable therapeutic agent.”

“For the first time, a study has found that cannabis use may be associated with a decreased risk of bladder cancer,  researchers reported at the American Urological Association 2013 annual meeting.

In a study of nearly 82,000 men, bladder cancer developed in 279 over an 11-year period. Subjects who smoked marijuana, but not tobacco, had a significant 45% decreased risk of bladder cancer compared with those who did not, after adjusting for age, body mass index, and race and ethnicity, according to lead investigator Anil A. Thomas, MD, a researcher with Southern California Permanent Medical Group in Los Angeles. Men who smoked tobacco, but not marijuana, had a significant 52% increased risk, a finding that is consistent with numerous previous studies. Men who smoked both had a 28% increased risk.

Of the 82,000 men, 41% reported ever using marijuana and 57% reported tobacco use; 27% reported used both tobacco and marijuana.”

Cannabis smokers show greater lung capacity and lower cancer levels than non-smokers

“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.”
