What Is Medical Marijuana?
Medical marijuana is a medicine made from the plant Cannabis sativa. Also known as cannabis, marijuana is legal for medical use in many states but is still a controlled substance under federal law.
Some of the more common medical uses for cannabis include:
- Alzheimer’s disease
- Amyotrophic lateral sclerosis (ALS)
- Cancer symptoms and treatment side effects
- Crohn’s disease
- Epilepsy
- Glaucoma
- HIV/AIDS
- Multiple sclerosis
- Muscle spasms
- Severe or chronic pain
- Severe nausea
What Are the Beneficial Compounds in Marijuana?
Cannabis contains more than 400 chemicals, but its two main active ingredients for medical treatment are THC and CBD. THC, or tetrahydrocannabinol, is the ingredient found in marijuana that causes people to feel a “high.” Yet, it’s also been shown to improve appetite and suppress nausea.
CBD, or cannabidiol, doesn’t produce a high feeling but helps relieve pain and may have numerous other benefits.
According to Dr. Barth Wilsey of the University of California in Davis, pain is often the primary reason most people seek out medical marijuana. The pain ranges from anything as minor as a headache to something as severe as mesothelioma cancer.
Laura Borgelt, PharmD of the University of Colorado’s School of Pharmacy and Pharmaceutical Sciences, stated that the chemicals in marijuana help the already natural chemicals that our bodies produce, which helps reduce pain.
Why Do Doctors Prescribe Marijuana to Cancer Patients?
Mesothelioma and other cancer patients suffer from various side effects, both from the disease itself and the effects of aggressive treatment options, such as chemotherapy and radiation therapy.
In numerous clinical trials that studied mesothelioma patients who used medical marijuana, patients not only experienced pain relief but also:
- A decrease in nausea
- Better sleep quality
- An increased appetite
- Diminished anxiety
- Improved food intake for IV patients (when smoked)
As with most medical treatments, marijuana has its own side effects, but the study participants indicated mild side effects. The most common side effects include:
- Dizziness
- Feeling paranoid
- Food digestion issues (slower to digest food)
- Red eyes
- Increased heartbeat
- Low blood pressure
- Hallucinations
- Dry mouth
Can Medical Marijuana Treat Cancer Directly?
Medical marijuana is mostly used to treat symptoms and treatment side effects in cancer patients, not to treat the cancer directly. However, studies indicate that compounds in cannabis could have antitumor potential:
- In an animal study, cannabinoids improved the effectiveness of chemotherapy treatments.
- Another animal study showed that cannabis compounds could slow or even stop tumor growth.
- A study using cell cultures found that cannabinoids killed breast cancer cells and not healthy cells.
Because marijuana is a federally controlled substance, research into its anti-cancer capabilities is limited. With growing legalizations by state, this kind of research is picking up pace.
What Are the Prescription Medical Marijuana Drugs?
The U.S. Food and Drug Administration (FDA) has approved three prescription drugs based on cannabinoids. A fourth drug is in clinical trials in the U.S. and is already in use in Canada and Europe.
- Cesamet (nabilone). Cesamet is a synthetic THC sometimes prescribed to treat severe chemotherapy nausea when other drugs have not helped.
- Epidiolex® (cannabidiol). This CBD product is used to treat some patients with seizure disorders.
- Marinol (dronabinol). Marinol is synthetic THC. It treats severe chemotherapy nausea and vomiting. It can also be used to help HIV/AIDS patients with poor appetite gain weight.
- Sativex (nabiximols). Not yet FDA-approved, Sativex is used in Europe and Canada to treat pain associated with cancer. It contains both THC and CBD.
Can CBD Help With Mesothelioma?
CBD oil is becoming increasingly popular as more research details its tremendous benefits. This includes patients with mesothelioma and children with severe epilepsy and other painful disorders that traditional medication hasn’t helped.
CBD is not the same as medical marijuana because it is not a mind-altering compound. CBD oil uses non-intoxicating cannabis as an oil-based medication that’s said to treat several ailments, including cancer. Several mesothelioma patients reported great success in battling pain after using CBD oil.
There are still relatively few studies on adults with mesothelioma and CBD oil. However, several studies show it would work as a treatment for lung cancer in general.
- In 2007, Harvard University scientists studied CBD oil and cancer and determined that cannabidiol stops epithelial growth in lung cancer cell migration.
- In 2011, Harvard researchers performed another study, which determined that cannabinoids can be used to treat lung cancer.
- The American Cancer Society (ACS) published an article entitled “Marijuana and Cancer,” which backed the findings. The story claimed that “certain cannabinoids may slow growth and reduce the spread of some forms of cancer.”
- CBD oil can be taken by simply adding drops onto your tongue and swallowing. There’s no conclusive study to determine how many drops to take or how many times per day, but research indicates that it more likely depends on each person’s health makeup.
- In 2012, two scientists from San Francisco’s California Pacific Medical Center found that the CBD compound can stop malignant growth in numerous types of cancer. According to one of the scientists involved in the study, Pierre Desprez:
“What we found was that his Cannabidiol could essentially ‘turn off’ the ID-1……We started by researching breast cancer. But now we’ve found that Cannabidiol works with many kinds of aggressive cancers—brain, prostate—any kind in which these high levels of ID-1 are present.”
ID-1 is a gene found in the body that causes cancer to metastasize.
Where Is Medical Marijuana Legal?

Is Medical Marijuana Right for Me?
Cannabis isn’t right for everyone. Talk to your doctors before trying any medical marijuana products. As you consider using medical marijuana, keep these important facts in mind:
- Using cannabis to treat pain isn’t new. It actually dates back to more than 3,000 years ago.
- Cannabis is considered a controlled substance in the U.S., but many states allow its use with a prescription and a doctor’s recommendation.
- Medical marijuana can be inhaled, taken by mouth, or in the spray form.
- The National Cancer Institute (NCI) confirms that medical marijuana can assist cancer patients with the painful side effects of traditional treatment options.
- Cannabis has been proven to kill cancer cells and promote antitumor activity.
- There is still not enough evidence to suggest whether inhaling medical marijuana is better or worse than ingesting it.
- Medical marijuana can cause side effects, but most people report that the effects are minor.
- Cannabis is not yet approved by the FDA for cancer treatment, therefore, it remains a complementary and alternative form of treatment or a treatment for symptoms.
- Animal studies have shown that delta-9-THC can increase appetite and decrease nausea.
- Animal studies have also shown that medical marijuana can decrease nerve problems, reducing pain, tingling, swelling, and numbness.
Who Should Not Use Medical Marijuana?
Medical marijuana has mainly proven safe for most people with minimal and minor side effects. However, some people should not use it because of safety concerns:
- Pregnant women
- People with a history of psychosis
- People with heart disease
You should always talk to your doctors before trying any new medication, supplement, or herb, including medical cannabis. There could be important reasons that it isn’t right for you.
How Can I Get Access to Medical Marijuana?
If you are interested in trying medical marijuana, talk to your medical team. If it is legal in your state, they can recommend products or even prescribe something to help you.
There are a few different forms of medical marijuana with important differences to consider:
- Inhaling marijuana. The traditional recreational way to use marijuana is to smoke it. This isn’t ideal for most mesothelioma patients who have respiratory limitations and symptoms. One benefit of inhaling it is that the effects are generally felt right away.
- Edible marijuana. It is now easy to find edible products with varying amounts of CBD or THC. Edibles take longer to work, but many people also find they produce milder psychoactive effects. Edibles often come in the form of baked goods or candies, but you can also find tinctures and capsules.
- Topical marijuana. Less common but increasingly available are creams and lotions that contain cannabinoids. These can be applied directly to an area of the body that is in pain. CBD topical products are the most common.
