Form of medical marijuana won’t get you high, but it’s creating a buzz

Posted on by

“The one-armed man loitered in the waiting room for much of the morning, flipping through magazines with impressive dexterity, quietly waiting for word that the doctor would see him. Now.

William Courtney, MD, offered the chair to the right of the desk, the one occupied during regular office hours by a steady stream of patients seeking a doctor’s recommendation for marijuana. In California, such a recommendation means an adult may grow, buy and smoke marijuana, all while remaining safely within the confines of state law.

The singular peculiarity of Courtney’s “pot doc” practice here in Northern California is what he recommends: Don’t smoke the stuff, he tells patients. Eat it.”

Juicing Raw Cannabis for Greater Health

Posted on by

“If you find yourself in the doctors chair at the office of Dr. William Courtney, Willits, California you will be advised; we shouldn’t be smoking our marijuana, we should be eating it!  After I read the story in the Washington Post, “Form of medical marijuana won’t get you high but is creating quite a buzz” written by Karl Vick,  I decided to look into it more.

CBD (Cannabidiol), one of the main constituents of the cannabis plant has been proven medically to relieve convulsion, inflammation, anxiety and nausea, as well as inhibit cancer cell growth.  Recent studies have shown it to be an effective atypical anti-psychotic in treating schizophrenia.  CBD also interferes with the amount of THC your brain processes, balancing the psychotropic effect of marijuana.”

Israeli Study Finds Patients with Chronic Disease Benefit from Marijuana

Posted on by

“A new study out of Israel looks to change that. Led by Zach Klein, a specialist in medical marijuana policy and the director of the documentary Prescribed Grass, researchers at Tel Aviv University tested medical marijuana on 19 nursing home residents. Patients were treated with cannabis in the form of powder, oil, vapor, or smoke three times daily over the course of a year.

 Seventeen of the 19 patients regained lost weight, and symptoms of pain, stiffness, tremors, insomnia, and PTSD decreased drastically. Their moods and communication skills also improved, and they had fewer nightmares and flashbacks, according to Klein.

“After I found this, everything has been better,” Moshe Rute, a Holocaust survivor stricken by nightmares and the effects of a stroke told the Times of Israel. “I’m still a Holocaust child, but I’m finally able to better cope.”

The 80-year-old Hadarim resident is one of 11,000 Israelis with permits from the government to use marijuana for medical purposes, a number that is growing rapidly.

“This is just the tip of the iceberg. It’s the future,” Klein said to the Times. “This is God’s doing, and it’s marvelous in our eyes.”

Perhaps as important as the improvement in pain management and quality of life was marijuana’s ability to replace some of the medication taken by the patients. By the end of the study, 72 percent were able to reduce the number of drugs they were taking daily. This includes medication for Parkinson’s disease, pain relievers, antipsychotics, and mood stabilizers, many of which can have debilitating and severe side effects.

“We know how to extend life, but sometimes it’s not pleasant and can cause a great deal of suffering, so we’re looking to alleviate this, to add quality to longevity,” head nurse Inbal Sikorin told the Times. “Cannabis meets this need. Almost all our patients are eating again, and their moods have improved tremendously.”

The country that discovered tetrahydrocannabinol (THC) the psychoactive ingredient in cannabis, in the 1960’s doesn’t have the stigma attached to marijuana that the United States does, as even senior rabbis have no qualms with its use or spread.

Klein is working on a new study at Israel’s Reuth Medical Center, in which he hopes to establish a connection between medical cannabis and improved swallowing. One of the biggest concerns with chronically ill patients is food intake, and Klein believes that cannabis, which can stimulate regions of the brain associated with swallowing reflexes, will have a positive impact.”

Cannabis may help reverse dementia: study

Posted on by

“It makes most people a little foggy-headed, but scientists are investigating whether an active ingredient in cannabis could actually stave off dementia.

A team from Neuroscience Research Australia is in the early stages of research examining if one of the main active ingredients in cannabis, called cannabidiol, could reverse some of the symptoms of memory loss in animals.

Tim Karl, a senior research fellow with the group, said cannabidiol does not have the same psychoactive effects as the main component of marijuana, THC, but it has been found to have anti-inflammatory, antioxidant and other effects that could be beneficial for the brain.”

The pharmacologic and clinical effects of medical cannabis.

Posted on by

“Cannabis, or marijuana, has been used for medicinal purposes for many years. Several types of cannabinoid medicines are available in the United States and Canada. Dronabinol (schedule III), nabilone (schedule II), and nabiximols (not U.S. Food and Drug Administration approved) are cannabis-derived pharmaceuticals.

Medical cannabis or medical marijuana, a leafy plant cultivated for the production of its leaves and flowering tops, is a schedule I drug, but patients obtain it through cannabis dispensaries and statewide programs. The effect that cannabinoid compounds have on the cannabinoid receptors (CB(1) and CB(2) ) found in the brain can create varying pharmacologic responses based on formulation and patient characteristics. The cannabinoid Δ(9) -tetrahydrocannabinol has been determined to have the primary psychoactive effects; the effects of several other key cannabinoid compounds have yet to be fully elucidated. Dronabinol and nabilone are indicated for the treatment of nausea and vomiting associated with cancer chemotherapy and of anorexia associated with weight loss in patients with acquired immune deficiency syndrome. However, pain and muscle spasms are the most common reasons that medical cannabis is being recommended.

Studies of medical cannabis show significant improvement in various types of pain and muscle spasticity. Reported adverse effects are typically not serious, with the most common being dizziness. Safety concerns regarding cannabis include the increased risk of developing schizophrenia with adolescent use, impairments in memory and cognition, accidental pediatric ingestions, and lack of safety packaging for medical cannabis formulations. This article will describe the pharmacology of cannabis, effects of various dosage formulations, therapeutics benefits and risks of cannabis for pain and muscle spasm, and safety concerns of medical cannabis use.”

Modulation of Cannabinoid Receptor Activation as a Neuroprotective Strategy for EAE and Stroke

Posted on by

“These results provide evidence that alteration of the activation patterns of the various cannabinoid receptors warrant consideration for future therapeutic strategies.

Interest in the medicinal use of Cannabis sativa (marijuana) has a long historical record, extending back thousands of years. In comparison to the extensive history for medicinal applications of marijuana, the existence of an “endocannabinoid system”, with important homeostatic and pathologic functions, has only recently gained appreciation. The endocannabinoid system consists of endogenously produced cannabinoids, their receptors, and the enzymes responsible for their synthesis and degradation…

Although used in ancient Greece, Rome, and China for therapeutic purposes, concern about the use of cannabinoids as a drug of abuse has dampened interest in developing the potential therapeutic benefits of these compounds. However, a better understanding of the biologic effects has led recently to an upsurge in interest for the development of therapeutic drugs through modification of the endocannabinoid system. An additional incentive was provided by the development of synthetic cannabinoid analogs and specific inhibitors of cannabinoid receptors. Several excellent reviews cover the therapeutic potential of cannabinoids….

The present review is focused on the effects of CB2 receptor activation in models of multiple sclerosis (experimental autoimmune encephalomyelitis) and stroke (middle cerebral occlusion/reperfusion).

In summary, selective CB2 receptor agonists and CB1 receptor antagonists have significant potential for neuroprotection in animal models of two devastating diseases that currently lack effective treatment options.”

“A Ferndale man claims he’s found a cure for his cancer and it’s now legal in Michigan.”

%name Skin Cancer Patient Says Oil From Medical Marijuana Is A Cure.

“WWJ’s Sandra McNeill spoke with Michael McShane who claims he’s been using a topical oil made from medical marijuana on the skin cancer on his forehead and in just over two months it’s nearly gone.

“I’ve got biopsies, chart notes, photographs … in about three weeks I’m going to go back  and really wrap this part of the case up,” said McShane. “It’s made the same way a lot of the fragrances and perfumes are made, and the oil is applied, in my case, directly to the skin, and within 10 weeks my cancer is gone.

“From a topical standpoint I don’t experience any euphoria,” said McShane.

McShane freely admits that he has smoked marijuana since he was in his teens, “It went from a party to a cure for cancer,” he said.”

Inhibition of skin tumor growth and angiogenesis in vivo by activation of cannabinoid receptors

Posted on by

“Cannabinoids inhibit skin tumor growth in vivo. Here we show that the CB1 and the CB2 receptor are expressed in normal skin and skin tumors of mice and humans. In cell culture experiments pharmacological activation of cannabinoid receptors induced the apoptotic death of tumorigenic epidermal cells, whereas the viability of nontransformed epidermal cells remained unaffected. Local administration of the mixed CB1/CB2 agonist WIN-55,212-2 or the selective CB2 agonist JWH-133 induced a considerable growth inhibition of malignant tumors generated by inoculation of epidermal tumor cells into nude mice. Cannabinoid-treated tumors showed an increased number of apoptotic cells.

 

Cannabinoids, the active components of Cannabis sativa linnaeus (marijuana)…

Marijuana and its derivatives have been used in medicine for many centuries, and currently there is a renaissance in the study of the therapeutic effects of cannabinoids… cannabinoids may be potential antitumoral agents owing to their ability to induce the regression of various types of tumors, including lung adenocarcinoma, glioma, and thyroid epithelioma in animal models.

This background prompted us to explore whether (a) the skin and skin tumors express cannabinoid receptors; (b) cannabinoid receptor activation exerts a growth-inhibiting action on skin tumors in vivo; and (c) inhibition of angiogenesis is implicated in the anti-tumoral effect of cannabinoids.

Our data show that (a) CB1 and CB2 receptors are present in the skin and skin tumors; (b) local cannabinoid receptor activation induces the regression of skin tumors in vivo; and (c) at least two mechanisms may be involved in this action: direct apoptosis of tumor cells and inhibition of tumor angiogenesis.

These results support a new therapeutic approach for the treatment of skin tumors.”

A Population-based Case-Control Study of Marijuana Use and Head and Neck Squamous Cell Carcinoma

Posted on by

“Marijuana (Cannabis sativa) contains more than 60 unique compounds known as cannabinoids. Cannabinoids, constituents of marijuana smoke, have been recognized to have potential antitumor properties. However, the epidemiological evidence addressing the relationship between marijuana use and the induction of head and neck cancer (HNSCC) is inconsistent and conflicting. An early epidemiological study reported that marijuana use was associated with an elevated risk for head and neck cancer.  However, more recent studies have failed to confirm the association of marijuana use with an increased head and neck cancer risk.

 In fact, many of these studies reported non-significant protective estimates of effect, consistent with a possible anticarcinogenic action of cannabinoids.

A recent epidemiologic review raised the need for additional, well conducted, large studies to clarify the nature of the association of marijuana use with the risk of cancer, especially head and neck cancer. In order to further elucidate the association between marijuana use and head neck cancer risk, we assessed marijuana use in detail in a population-based case-control study.

After adjusting for potential confounders (including smoking and alcohol drinking), 10 to 20 years of marijuana use was associated with a significantly reduced risk of HNSCC.

Our study suggests that moderate marijuana use is associated with reduced risk of HNSCC.”

Doctors utilise marijuana as pain relief

Posted on by

“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. 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. 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’s findings was first published 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. 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.”

“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. But you could never get enough Cannabidiol for it to be effective just from smoking.”

Furthermore, the team has started synthesizing the compound in the lab instead of using the plant in an effort to make it more potent.”It’s a common practice. But hopefully it will also keep us clear of any obstacles while seeking approval.””
