Smoking Cannabis Reduces Pain, Helps Sleep And Improves Mood For Those With Chronic Symptoms

“For patients with chronic (long-term) neuropathic pain, smoking cannabis was found to reduce symptoms of pain, improve mood and help sleep, a report published in CMAJ (Canadian Medical Journal Association) revealed. When damage or dysfunction of the nervous system results in chronic neuropathic pain, patients have few treatment options, such as antidepressants, local anesthetics, anticonvulsants or opioids. However, these medications often have undesirable side effects and do not work for everybody.

The authors inform that oral cannabinoids have been effective in reducing the symptoms of some types of pain. However, they many have different effects and risks compared to smoked cannabis.

Investigators from McGill University Health Centre (MUHC) and McGill University carried out a randomized, controlled trial to determine the analgesic effect of smoked cannabis in 21 patients, aged 18 years or more, all of them with chronic neuropathic pain. THC levels (drug potencies) were divided into 2.5%, 6% and 9.4%. Some participants also received a placebo (0%).

The researchers inform that there was a correlation between increased THC content and better sleep quality. Symptoms of depression and/or anxiety were also reduced at 9.5% THC level.”

[Marihuana and cannabinoids as medicaments].

“Biological activity of cannabinoids is caused by binding to two cannabinoid receptors CB1 and CB2. Psychoactive is not only tetrahydrocannabinol (THC) but also: cannabidiol, cannabigerol or cannabichromen. Formerly, the usefulness of hemp was assessed in the relation to temporary appeasement of the symptoms of some ailments as nausea or vomiting.

 Present discoveries indicates that cannabis-based drugs has shown ability to alleviate of autoimmunological disorders such as: Multiple sclerosis (MS), Rheumatoid arthritis (RA) or inflammatory bowel disease. Another studies indicates that cannabinoids play role in treatment of neurological disorders like Alzheimer disease or Amyotrophic lateral sclerosis (ALS) or even can reduce spreading of tumor cells.

 Cannabinoids stand out high safety profile considering acute toxicity, it is low possibility of deadly overdosing and side-effects are comprise in range of tolerated side-effects of other medications.

In some countries marinol and nabilone are used as anti vomiting and nausea drug. First cannabis-based drug containg naturally occurring cannabinoids is Sativex. Sativex is delivered in an mucosal spray for patients suffering from spasticity in MS, pain relevant with cancer and neuropathic pain of various origin. Despite the relatively low acute toxicity of cannabinoids they should be avoid in patients with psychotic disorders, pregnant or breastfeeding woman. Cannabinoids prolong a time of reaction and decrease power of concentration that’s why driving any vehicles is forbidden.

 Cannabis side-effects varies and depend from several factors like administrated dose, rout of administration and present state of mind. After sudden break from long-lasting use, withdrawal symptoms can appear, although they entirely disappear after a week or two.”

Pot patch considered medical breakthrough

“Advocates are fighting to legalize marijuana. The University of Mississippi has the only legally grown marijuana crop in the nation.Faculty members and student researchers have now developed a new patch that could potentially provide help to patients who need it.

The patch developed at Ole Miss could help patients overcome problems associated with taking the drug in pill form. The patch is placed above the gum line.

“In addition to pain, it will include things like reducing intraocular pressure and therefore would be good for glaucoma. [It] will be good for alleviating the nausea and vomiting associated with chemotherapy; it would also be good for appetite stimulation for patients suffering from the syndrome, anti-inflammatory activity, anti-anxiety,” explains Dr. ElSohly.”

Cannabis could provide relief for Parkinson’s pain

“As many as eight out of every 10 of those with Parkinson’s disease suffer from inexplicable pains that until now have been left untreated because they were thought to be an inevitable part of the progressive and eventually fatal neurological disease. Parkinson’s, a brain disorder that leads to tremors and difficulty with walking, coordination and movement, usually develops after age 50 and is one of the most common nervous system disorders of the elderly.But new research at the Rabin Medical Center- Beilinson Campus has found that genetic factors explain such Parkinson’s pain, and that the new understanding will make unique treatments possible. Eight genes known to be involved in pain were examined in 237 Parkinson’s patients, according to a research paper published recently in the European Journal of Pain, and the observed variations were connected to functions of cannabis-like substances (cannabinoids) in the brain.

Research project head Prof. Ruth Djaldetti, a senior physician in the neurology department and head of the movement disorders clinic, said that the results support the treatment of Parkinson’s patients with medical marijuana.

Djaldetti encourages more research into the use of cannabis for pain relief.

There are some 20,000 people with Parkinson’s in Israel, and about 50 percent to 80% of them suffer from this previously unexplained and untreated pain. Djaldetti expects that in the future, gene mapping will make it possible to suit personalized medication to these patients.”

 

Cannabis compound can help cells

“Cannabis has been used recreationally and for medicinal purposes for centuries, yet its 60 plus active components are only partly understood. Now scientists have discovered how a compound in cannabis can help cells to function in our bodies, and aid recovery after a damaging event.

In a paper published in the Journal of Neuroscience, the researchers report on their studies into cannabidiol – a naturally occurring molecule found in cannabis.

Also known as CBD, it is not the constituent that gives the high – that compound is called tetrahydrocannabinol or THC – and so may be more acceptable as a drug treatment.

Both compounds are currently used in a pharmaceutical medicine to help patients relieve pain and other symptoms of Multiple Sclerosis.

Now researchers have discovered how CBD actually works within brain cells.

By interacting with mitochondria – which are the power generators of all cells – it can help maintain normal levels of calcium allowing cells to function properly and providing a greater resistance to damage.

Disturbance of calcium levels has long been associated with a number of brain disorders. So the finding could have implications for the development of new treatments for disorders related to malfunctioning mitochondria.

Dr Bettina Platt, from the University’s School of Medical Sciences, said: “Scientists have known for a long time that cannabidiol can help with pain relief but we never really knew how it worked.

“However we have discovered what it actually does at the cellular level.

“We are hoping that our findings can instruct the development of cannabidiol based treatments for disorders related to mitochondrial dysfunction such as Parkinson’s disease or Huntington’s disease.”

Israeli Study Finds Patients with Chronic Disease Benefit from Marijuana

“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.”

The pharmacologic and clinical effects of medical cannabis.

“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.”

Peripheral Cannabinoids Attenuate Carcinoma Induced Nociception in Mice

“Cancer pain remains poorly understood and there are no effective therapies…

 We tested whether a local CBr2 agonist produces antinociception. Our findings suggest that a peripheral CBr2 agonist could provide relief for cancer patients. Cannabinoids also potentiate the analgesic effects of morphine and prevent tolerance.

These desirable effects of cannabinoids show promise for management of cancer pain and may lead to improved analgesic therapy.

These findings support the suggestion that cannabinoids are capable of producing antinociception in carcinoma-induced pain.”

Cannabidiol bioavailability after nasal and transdermal application: effect of permeation enhancers.

“The nonpsychoactive cannabinoid, cannabidiol (CBD), has great potential for the treatment of chronic and ‘breakthrough’ pain that may occur in certain conditions like cancer. To fulfill this goal, suitable noninvasive drug delivery systems need to be developed for CBD. Chronic pain relief can be best achieved through the transdermal route, whereas ‘breakthrough’ pain can be best alleviated with intranasal (IN) delivery. Combining IN and transdermal delivery for CBD may serve to provide patient needs-driven treatment in the form of a nonaddictive nonopioid therapy.

CONCLUSION:

The results of this study indicated that CBD could be successfully delivered through the IN and transdermal routes.”
