Cannabis, also known as marijuana, comes from the Cannabis plant and contains natural chemicals called cannabinoids. The two main cannabinoids are THC, which can cause a “high,” and CBD, which does not cause intoxication and may help reduce pain, inflammation, and anxiety. Cannabis products include dried leaves, oils, capsules, and sprays. CBD oil is a type of cannabis extract that often contains mostly cannabidiol (CBD) and sometimes THC. These products are sometimes called medical cannabis or cannabis extracts.
People with cancer may use cannabis or CBD oil to help manage symptoms caused by cancer or its treatments. Common symptoms include nausea and vomiting from chemotherapy, pain, anxiety, loss of appetite, muscle spasms, and sleep difficulties. Two cannabinoid-based drugs are approved by the U.S. Food and Drug Administration (FDA) to treat chemotherapy-related nausea and vomiting, but cannabis or CBD oil products themselves are not approved to treat cancer or cure it. Instead, they are often considered part of supportive or complementary care to improve quality of life during cancer treatment.

Some patients report relief from symptoms when using these products, but effects can vary widely depending on the product’s strength and composition. It’s important to know that cannabis and CBD oil are not replacements for standard cancer treatments or prescribed medications.

Your care team can help you weigh the potential benefits and risks based on your individual health situation.
