10 Most Common Reasons People Use Medical Marijuana

Published on

Over 30 states in America currently allow medical marijuana. But not all states allow the same qualifying conditions for medicinal cannabis. Some allow it for virtually every condition that could possibly benefit from it, while others are far more restrictive on what qualifies. But there are some conditions that are accepted virtually everywhere in the U.S.

Here are the 10 most common reasons people use medical marijuana:

1. Cancer

Almost all states that allow medical marijuana allow it for cancer patients. Medicinal cannabis helps treat the pain that accompanies cancer, as well as helping to treat other symptoms related to it such as nausea caused by chemotherapy.

2. Chronic Pain

Chronic pain sort of touches multiple other conditions on this, such as cancer mentioned above. But many states aren’t requiring a major condition to cause a person’s pain anymore. More and more states realize the dangers of prescribing opioids, and are allowing doctors to give cannabis instead.

3. Epilepsy/​Seizure Disorders

Epilepsy and other seizure disorders is another condition that almost every state allows medical marijuana for. In fact, many states without medical marijuana still allow CBD oil to treat epilepsy or other similar conditions thanks to the overwhelming amount of evidence showing how cannabis can help treat them.


HIV/AIDS is another condition that almost every state allows for medical marijuana. The biggest reasons why medical marijuana helps HIV/AIDS patients is to help treat their nausea and loss of appetite.


More and more studies are coming out showing that cannabis can help people with post-traumatic stress disorder to exhibit less symptoms. And as a result, more and more states are allowing medical marijuana to treat it, particularly since so many military veterans are advocating for it.

6. Crohn’s Disease

Crohn’s disease is a condition that causes inflammation in the digestive tract, which can lead to abdominal pain, gastrointestinal issues and malnutrition. Marijuana has anti-inflammatory properties, and many people with Crohn’s use cannabis because it’s safer and has less side-effects than prescription medications for the the disease.

7. Multiple Sclerosis

Multiple Sclerosis (MS) is a disease that essentially disrupts information between the brain and the nerves throughout the body. This can lead to pain, insomnia, inflammation, musclpe spasms and more. Luckily all of those conditions can be treated with medical marijuana, so it’s very effective at treating the symptoms of this condition.

8. Neurodegenerative Disease

Neurodegenerative diseases such as Lou Gehrig’s Disease, Parkinson’s, Alzheimer’s, Huntington’s and more are often allowed medical marijuana. Unfortunately, it’s rare for states to allow medicinal cannabis for all of these conditions.

9. Glaucoma

The old joke in TV and movies was people would claim they have glaucoma to justify their medical marijuana use. But it was one of the first conditions that doctors said does benefit from medical marijuana, although now many ophthalmologists say you should only use non-smokeable forms of cannabis to treat glaucoma.

10. Arthritis

Technically, arthritis could be put under chronic pain, and arthritis patients in states that don’t allow the condition as a qualification for medical marijuana just get a prescription for pain. But many states allow arthritis specifically as a qualifier for medical marijuana. As a fun fact, around two-thirds of Canada’s medical marijuana patients use it for arthritis.
