Shall a Cancer Patient use CBD Oil for Cancer

With its recreational and medicinal benefits, CBD oil has become a household name in states that have legalized its sale and use. There was a time when it was available only at vitamin shops. Now you can buy CBD oil at your local pharmacy, grocery store or even yoga studio. CBD products come in different forms. If you are using CBD oil, a few drops under your tongue is enough to get its health benefits. You can apply roll-on to the skin. Similarly, you can use vape pens to inhale CBD oil. Producers also create edible products by adding CBD into foods.

When a lot is written about CBD oil for cancer, a patient experiencing pain and other symptoms of the disease will definitely want to know if CBD really helps. Does it at least provide relief from symptoms of this disease? It is important to separate facts from myths and false claims. 

If you think that CBD oil for cancer can help, here is what you need to know. 

Hemp and marijuana are two varieties of the cannabis sativa plant. Both contain tetrahydrocannabinol (THC) and cannabidiol (CBD). Both CBD and THC are active ingredients. However, THC content of hemp is far less than that of a marijuana plant. THC is a psychoactive substance, while CBD is not. CBD does not cause any euphoric effects with its health benefits.  

So, can CBD oil for cancer cure this disease? 

No. There is nothing called CBD for cancer cure. No clinical evidence shows that CBD oil can be a cure for the disease. 

Does CBD oil for cancer alleviate cancer symptoms? Does it provide relief from the side effects of cancer treatment? 

Only fewer studies have addressed these questions. Only a small number of these studies are standardized. Some reports suggest that CBD and THC may be helpful for: 


  • Vomiting 
  • Nausea 
  • Anorexia 
  • Anxiety 
  • Neuropathy 
  • Insomnia 
  • Depression 


Some synthetic cannabinoids such as dronabinol are approved for nausea and vomiting due to chemotherapy. However, the results of these synthetic cannabinoids are not as effective as conventional anti-nausea medications. 

The US Food and Drug Administration does not approve the use of CBD oil for cancer treatment or treatment of cancer treatment side-effects. The agency also does not approve CBD for relief from symptoms. The FDA has approved only one CBD product, Epidiolex, for the treatment of Dravet syndrome and Lennox-Gastaut syndrome. Both syndromes are related to epilepsy. There is no other CBD product approved for any other medical purpose. 

Regulation, quality and cleanliness are the biggest concerns linked with CBD products. The FDA regulates all drugs and dietary supplements. CBD oil and other products are not well regulated. If you visit a reputable store, you can get products containing the exact amount CBD or THC as mentioned on the label. However, you cannot deny the existence of a black market. You don’t want to purchase CBD oil with significantly more THC and less CBD content than advertised. 

Both CBD and THC are extracted from marijuana and hemp and extraction processes are also very similar. As a result, CBD oil may contain a small amount of THC. Therefore, you must purchase lab-tested CBD products as a high enough concentration of THC can produce psychoactive effects. Sometimes, the THC content of the plant is higher than the expected levels. This effect can be due to:


  • Prolonged flowering periods 
  • Environment 
  • Pollination between female and male plants 
  • Cross-contamination  


Make sure that THC levels are less than 0.3% in your CBD oil for cancer. It is also important to know that CBD can interact with some medications. Immunocompromised patients are susceptible to fungal and bacterial infections. Even if you are not an immunocompromised patient, don’t take CBD oil for cancer, arthritis or any other disease without your doctor’s advice. 

A cancer patient must understand that CBD is neither a medicine, vitamin or supplement. Its interaction with certain drugs can reduce the efficacy of the drug or it can be harmful as well. You must speak to your doctor before using CBD oil for cancer. 

You also need to learn about the complex legal status of CBD. It is not a Schedule I drug. States have different laws to regulate the sale and use of both recreational and medicinal marijuana.
