While most countries still debate on the legalization of marijuana, some countries have already legalized the used of this herb with medicinal properties that this article will talk about.

Richard Cowan, the editor of MarijuanaNews.com said that ĸThere really is massive proof that the suppression of medical cannabis represents the greatest failure of the institutions of a free society, medicine, journalism, science and our fundamental values. Here are major medical uses of the cannabis:

Marijuana VS Tobacco

Marijuana, according to Journal of the American Medical Association, has the ability to increase lung capacity and does not pose any harm on the natural functioning of the lungs.

Research has actually showed that tobacco smokers have decreased lung function over the twenty-year duration of the research while pot users demonstrated an increase in their lungs’ capacity and this good effect may be attributed to the deep breaths that users take while drawing in the drug.

Tumors And Cancers

Cannabinoids are marijuana’s active component which was proven to eliminate cancer cells of the laboratory-grown test animals and the THC (tetrahydrocannabinol) in marijuana was found useful especially in curing lung cancer because of its ability to activate the receptors.

Moreover, research has shown that cannabis slows the increase of tumors as well as cancer cells production. It also reduces the side effects of radiation and chemotherapy such as vomiting and nausea.

In addition, a recent discovery in California Pacific Medical Center in 2007 revealed that a chemical contained in marijuana called cannabidiol prevents the spread of cancer. It turns off the Id-1 gene which was created by cancer cells and spreads throughout the body. Breast cancer cells with high Id-1 expression levels were examined and treated with cannabidiol. After treatment, the gene had decreased and became weak spreaders.

Reduced Anxiety

Marijuana relieves the side effects of chemotherapy like pain and nausea. In 2010, Harvard Medical School stated that these effects may be due to the reduced anxiety which in turn improves the mood of the user while at the same time acts as a low-dose sedative.

OCD and Tourette’s Syndrome

Studies show that cannabinols reduced most of the symptoms of Tourette ‘s syndrome for a number of hours with just one dose. There were less tics and twitches. Marijuana also has the ability to help those who have OCD.

Epileptic Seizures

A 2003 study have shown that marijuana can avert epileptic seizures because it has muscle relaxant properties. The Virginia Commonwealth University treated epileptic rats with marijuana and this relieved the rats of up to 10 hours without seizures. Cannabinoids and THC bound to the brain cells in charge for the control of excitability and relaxation.


Cannabis has been revealed to medically treat migraines including nausea, dizziness and light sensitivity.

Glaucoma And Blindness Prevention

Marijuana is used nowadays as a treatment and as a prevention for glaucoma, which is the eye condition wherein pressures in the eyeballs are increased, thereby damaging the optic nerve and leads to blindness.

Marijuana actually has the ability to decrease pressure in the eye, as stated by the National Eye Institute. In fact, a 1970 study revealed that smoking marijuana reduces intraocular pressure or IOP in the eyes of people with normal eye pressure and those with glaucoma. This effect may then slow the development of the disease and thereby prevent loss of vision.

Multiple sclerosis

Canadian Medical Association suggests that marijuana can ease the pain caused by multiple sclerosis. A study done by Jody Corey-Bloom on 30 individuals with multiple sclerosis that didn’t react to other treatments testified that after smoking pot, they were in a lesser amount of pain.

The THC bonded with the receptors present in the nerves and muscles which relieved the patients of the pain and controlled the muscle spasms.


Patients with ADHD and ADD have testified that cannabis has helped them relax and focus on their tasks. Also, they experienced a lesser amount of hyperactivity as well as impulsivity.

Alzheimer’s Disease

The Scripps Research Institute suggests that the progression of Alzheimer’s disease can be slowed down by marijuana.

In 2006, it was published that THC slows the amyloid plaques formation by overcrowding the enzyme that makes them. These plaques are what causes Alzheimer’s because they kill the brain cells.

Hepatitis C

Hepatitis C treatments have lots of negative side effects such as fatigue, muscle aches, nausea,loss of appetite as well as depression that can last for months which is why most people do not continue the treatment.

Fortunately, a 2006 study done by the European journal of Gastroenterology and Hepatology proved that 86% of patients who use marijuana while on treatment for Hepatitis C have successfully completed and finished their treatment while just 29% of non-smokers finished their cure. The reason may be that marijuana was able to reduce the side effects of the treatment.

Inflammatory Bowel Diseases

Ulcerative colitis and Crohn’s disease patients could gain from using marijuana. The University of Nottingham in 2010 has found that THC and cannabidiol work together with the cells in your body especially with those responsible for your immune responses and gut function. The cannabinoids lessens the permeability of your intestines making it more tightly bonded to prevent bacteria from passing through.


Marijuana eases pain, decreases inflammation and encourages sleep which help relieve discomfort and pain for rheumatoid arthritis patients. In fact, the rheumatology units of several hospitals offer their patients sativex, a cannabinoid-based pain reliever and just after two weeks, a significant decrease in pain and discomfort was observed by the patients thereby improving their sleep in comparison to those who use placebo.
