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.

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…”

Is marijuana bad for you?

Posted on by

“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.””

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.”

Evidence: Cannabinoid Therapy Reduces Breast Cancer Tumors

“Warning: Many alternative treatments are shams with zero proof. Most alternatives make claims that are not backed up by any evidence or hard empirical medical studies, are are not peer-reviewed. 
 
Peer review means your study and its claims will be vetted by a panel of the best doctors and other medical professionals in that field, for critical review. They will try to find fault in its methodology before publication and its recommendations for possible human treatment.
 
For any cannabis-based study strong enough to stand up to this critical review, and for it to be published in a major journal within such a field as cancer research, is incredible. That’s exactly how strong the evidence for cannabis medicine is starting to become.
 
Imagine that. This plant, this “great friend of humanity” which has helped us survive by giving early humans food, fuel, fiber and medicine, and who ancient healers wrote about in 6000 B.C., more than 8,000 years ago, is now coming back to prove itself and to help save us again.
 
And this time we are starting to find the evidence to back up the claims made for this plant over the centuries…”

“Benefits of Medical Cannabis”

medical marijuana

“Today, there are at least 17 states, including the District of Colombia, where cannabis is legal. Ohio, South Carolina, Colorado, New Jersey, California, and Michigan are just a few states that garnered strong support in the legalization of  medical cannabis. In Illinois, a bill legalizing the use of  cannabis needed the signature of Gov Pat Quinn. The legislation was approved by House and Senate, permitting doctors to prescribe cannabis for cancer and patients with HIV/AIDS and other diseases…

There is now quantifiable evidence that cannabis is beneficial in treating many disorders…

Moreover, the Medical Cannabis Research and the University of California found out that cannabis can treat HIV/AIDS and multiple sclerosis symptoms. It can even benefit cancer patients to mitigate the unpleasant side effects of chemotherapy or as an alternative treatment for cervical cancer, breast cancer, prostate cancer, lung cancer, colorectal cancer, brain cancer, and leukemia.”

Bay Area Researchers Claim Cannabis Can Cure Cancer

Posted on by

“Marijuana has been used for medicinal purposes–relieving stress and pain and fighting hunger and nausea–for centuries if not millennia. But now, a pair of doctors in San Francisco claim that they’ve compiled reliable data showing that a certain compound in cannabis–cannabidiol–may actually cure cancer.”

Bay Area Researchers Claim Cannabis Can Cure Cancer

“Unlike THC, the ingredient in marijuana that makes you feel stoned, cannabidiol is a non-toxic compound of the plant that has no psychoactive qualities, and it’s been the focus of an ongoing series of trials at the San Francisco-based California Pacific Medical Center. There, physicians Sean McAllister and Pierre Desprez claim they’ve successfully used cannabidiol to fight animal genes involved in the spread of cancer. Now they hope to be allowed to conduct anti-cancer research using cannabidiol on actual humans.”

Study Claims Marijuana Tied to Lower Bladder Cancer Risk – MSN

“New research says smoking pot may be less likely to cause bladder cancer than smoking cigarettes.The finding is potentially valuable, the study authors said, given the ongoing debate over legalizing marijuana for medical purposes.

More frequent marijuana use — smoking pot more than 500 times — was associated with greater risk reduction than infrequent marijuana use — smoking once or twice, the researchers found.

Thomas said that while the study saw a link between smoking marijuana and lower bladder cancer risk, compared to tobacco smokers, it did not prove a cause-and-effect relationship. He couldn’t explain the link, but speculated on the possible mechanism.

“The theory is that there are receptors in the bladder that are affected by cannabis,” he said. The cannabinoids [compounds] in the marijuana may link with the cannabinoid receptors in the bladder and somehow protect against cell changes that can lead to cancer, he said.

A man’s lifetime risk of bladder cancer is almost 4 percent, according to the American Cancer Society. This means about one in 26 men will develop bladder tumors.”

“New research says smoking pot may be less likely to cause bladder cancer than smoking cigarettes.

The finding is potentially valuable, the study authors said, given the ongoing debate over legalizing marijuana for medical purposes.

 

For the study, the researchers compared the risk of bladder cancer in more than 83,000 men who smoked cigarettes only, marijuana (cannabis) only, or both substances. The investigators found that men who only smoked pot were the least likely to develop bladder cancer over the course of 11 years.

“Cannabis use only was associated with a 45 percent reduction in bladder cancer incidence, and tobacco use only was associated with a 52 percent increase in bladder cancer,” said study author Dr. Anil A. Thomas, a fellow in urology at Kaiser Permanente Medical Center in Los Angeles.”
