With an increasing number of states and countries legalising medicinal marijuana, attitudes are changing towards what is one of the worlds most talked about substances.

This is mainly because the drug’s medicinal properties, CBD and THC, have been linked to a whole host of debilitating conditions including Glaucoma, Epilepsy, Parkinson’s Disease, MS, Anxiety, and Arthritis, amongst many others.

As a result, record numbers of patients are using to drug to treat symptoms such as nausea, sleep deprivation, chronic pain, and the severity and frequency of epileptic seizures.

The late Dr. Tod Mikuriya, a former national administrator of the U.S. government’s marijuana research programs, appeared in a well known film about the business of marijuana prohibition before his 2007 death called “The Union,” and was famously quoted stating: “After dealing with about 10,000 patents in the last 15 years, I’d say about 200 different medical conditions respond favourably to cannabis.”

But what are the health benefits that legitimise the legalisation of marijuana?

Alzheimer’s Disease

A significant amount of research has signalled that medicinal marijuana is an effective method of treating and managing the symptoms associated with Alzheimer’s Disease.

Scientists have discovered that THC (the psychoactive ingredient found in marijuana) can prevent an enzyme known as acetylcholinesterase from accelerating the formation of plaques in the brain, as well as protein clumps that are known to affect cognition and memory.


Glaucoma is a severe eye condition that can lead tothe complete loss of vision. Recognised as one of the leading causes of blindness in the world, Glaucoma is the result of increased pressure in the eyeball, which can cause the gradual loss of sight if left untreated.

However, over the past decade, research has revealed that marijuana is able to help reduce and relieve the intraocular pressure in the eye, which causes the damage to the optic nerve. It also helps to reverse deterioration too.

Multiple Sclerosis

Many MS patients use marijuana to help them manage the symptoms associated with the condition.

Although some case studies have indicated that the drug can cause dizziness and fatigue, many patientsare using the drug to help ease pain in their arms and legs.


An article published in the 2010 edition of Harvard Mental Health revealed that many recreational cannabis users have claimed that smoking marijuana actually helps to calm them down.

But that’s not all… the drug has also been proven to help patients suffering from depression as weekly users reported that “they had a less depressed mood, and fewer somantic complaints.”

Cancer/ Chemotherapy

The FDA and American Cancer Society have confirmed that the active ingredients in marijuana are able to”relieve nausea and vomiting and increase appetite in people with cancer and AIDS.”

The society has been quoted in a media report stating: “Marijuana has anti-bacterial properties, inhibits tumour growth, and enlarges the airways, which they believe can ease the severity of asthma attacks.”
