The second most common cannabinoid, cannabidiol CBD , doesn't cause mind-altering effects and could potentially have beneficial effects for treating disease. Marijuana and cannabinoids can be taken several different ways -- smoking dried leaves, swallowing pills or spraying liquid under the tongue are a few examples. What Is the Research on Cannabinoids and Parkinson's? Our bodies make natural cannabinoids that control sleep, appetite, mood and other processes by binding to receptors throughout the body and brain.
These receptors are found in particularly high numbers in the basal ganglia, a circuit of brain cells that controls movement and is affected in Parkinson's. Because the cannabinoids in marijuana bind to the receptors in our body and brain, researchers have looked at whether they could bind to basal ganglia and other receptors to modify the course of PD or help ease symptoms of disease.
Pre-clinical work, including several studies funded by MJFF, shows that cannabinoids may protect brain cells through antioxidant and anti-inflammatory mechanisms. Clinical studies have evaluated whether marijuana can ease Parkinson's motor and non-motor symptoms as well as levodopa-induced dyskinesia , involuntary movements that may result with long-term use of levodopa and many years of living with PD.
In general, trials show mixed results some positive, some negative , which leaves patients, doctors and researchers with insufficient evidence that medical marijuana and cannabinoids are an effective treatment for Parkinson's.
Formal studies on other non-motor symptoms have not been conducted, but many individuals cite anecdotal benefit on pain, anxiety and sleep problems as well as motor symptoms.
Neither participant nor researcher knows who is getting study drug or placebo. Why Is Researching Marijuana Difficult? Several factors limit the ability to perform research on marijuana and interpret results. Regulations surrounding marijuana research may deter investigators.
The federal government classifies marijuana as a Schedule I drug , a category reserved for drugs that have no current acceptable medical use and a high potential for abuse. Fox Foundation and others have previously called for a reclassification of marijuana , which would make it easier to conduct research.
Interpretation of research results is hampered by many variables, such as lack of standardized or known doses , and variable CBD and THC concentrations. Parkinson's research uses many different formulations oral cannabinoids and smoked marijuana, for example and varied doses. This difference in formulation and dosing from person to person and study to study makes it challenging to guide the use of marijuana for medical purposes.
Study size and design also can limit interpretation. Most marijuana studies include small numbers of patients. When few patients test drugs, it's less likely the group represents the larger Parkinson's population and results either positive or negative can be easily applied to most people with PD.
Some studies use questionnaires where people report their symptoms and marijuana use; others lack a placebo group. Results from such trials can make it difficult to determine how much potential benefit may be due to drug versus placebo effect. If you're considering medical marijuana, you and your doctor should weigh the potential benefits and risks, just as you would with any therapy.
In low doses, cannabinoids appear to be relatively well tolerated. But like any other drug, medical marijuana has potential side effects.
Discuss possible influences on cognition, mood and balance, especially if you are already experiencing changes in these areas. It's unclear how and to what extent marijuana could exacerbate these symptoms.
The potential for drug interactions between marijuana and prescription or over-the-counter medications is largely unknown, but adding marijuana to a complex regimen of medications could present a risk. As when adding any new therapy, review all your medications with your doctor and pharmacist.
Risks of long-term marijuana use haven't yet been established. Outside of clinical trials however, many years of marijuana use are associated with an increased risk of mood disorders and, particularly with smoking, lung cancer. And estimates state that about nine percent of users become addicted. Is Medical Marijuana for You? As of May , the District of Columbia and 29 states have passed legislation allowing the use of marijuana-based products for medical purposes.
The authorized medical conditions, formulations, and patient and physician requirements are different in each state.

He notes that some of the most common afflictions of old age, including mood problems, sleep issues and arthritic pain, may respond well to medical cannabis.
For older patients suffering from chronic pain, Dr. A study, published in the journal Health Affairs, found that physicians wrote fewer prescriptions for elderly and disabled patients who had legal access to medical marijuana.
Bell urges seniors interested in medical cannabis to talk to a family doctor. Increasingly, doctors will either write the prescription required by Health Canada, or refer a patient to a physician with more experience in treating patients with medical cannabis, he said.
Bell instructs colleagues about the use of medical cannabis through a continuing education program accredited by the College of Family Physicians of Canada, for which he receives consultant fees from the licensed medical marijuana industry. Patients with specific health problems may need access to hundreds of distinct cannabis species, and different ratios of CBD to THC, before they find something that works, he said.
Nuessler, 62, uses high-potency CBD oil from an unlicensed producer to take the edge off post-traumatic stress disorder.

Few choose to inhale, said Gill in Victoria. Many are former cigarette smokers. Milton Callwood, 46, fears authorities could remove his year-old father from his care if they discovered he is giving him cannabis from a Vancouver dispensary.
Callwood agreed to an interview on the condition he could use a pseudonym. He could not talk or swallow normal food. Since then, the tremors have largely subsided, Callwood said. His father can chew a hamburger or tell his son when he wants to go for a drive.
