CBD is 1 of the hundreds of chemicals found in the flowering cannabis plant. CBD does not have the psychoactive, or mind-altering, effects of another chemical found in cannabis called tetrahydrocannabinol (THC). THC is the chemical that causes people to experience a “high.” CBD, on the other hand, is being used by some to help ease pain, anxiety, and sleep issues.
There have been some studies that show that CBD, alone or together with THC, may relieve pain, insomnia, or anxiety, but these studies were not specific to people with cancer. While no studies to date have shown that CBD eases these side effects specifically in people with cancer or people receiving cancer treatment, some people with cancer have reported benefits in taking CBD, such as helping with nausea, vomiting, depression, and other side effects. According to ASCO guidelines, your doctor may consider prescribing cannabinoids for chronic pain management if you live in a state where it is legal. However, ASCO guidelines state that there is not enough evidence to support the use of cannabinoids for preventing nausea and vomiting in people with cancer receiving radiation therapy or chemotherapy.
What is CBD?
Cannabidiol, also known as CBD, is one of many chemicals found in the cannabis plant. It has been touted in some online forums as an alternative treatment, and even a cure, for many illnesses, including cancer. And, some people with cancer say that CBD has helped them as a complementary therapy in managing their symptoms and side effects from standard cancer treatment.
Studies to answer this question are underway. Some scientists are studying whether CBD could relieve some of the side effects of cancer and its treatment, such as pain, insomnia, anxiety, or nausea. Other scientists are studying whether CBD could potentially slow or stop the growth of cancer.
You may find stories online of people discussing the benefits of CBD as a cancer treatment or as relief for side effects. Please remember that such personal stories, while they may be well-meaning, are shared without scientific study and do not constitute evidence. The safety and efficacy of CBD for people with cancer still has to be proven in large, randomized, controlled clinical trials.
CBD oil (cannabidiol) is everywhere these days. Once available only at novelty or vitamin shops, it’s now also at your local grocery store, pharmacy or even yoga studio.
In terms of purity, THC and CBD are both extracted from hemp and marijuana using essentially similar processes. But trace amounts of THC could still end up in CBD oil. And if the THC is at a high enough concentration, it could produce the psychoactive effects that THC is known for.
Yes. Epidiolex. It was originally approved in 2018 for the treatment of two conditions, both related to epilepsy: Lennox-Gastaut syndrome and Dravet syndrome. But aside from Epidiolex, no CBD product has been approved by the FDA for any other medical purpose.
At the national level, any product of marijuana — including CBD — is still technically illegal when used medically. Although the 2018 Farm Bill legalized the production of hemp nationally, that’s only permitted if it’s not marketed for medical use or as a dietary supplement. CBD products intended for medical use should undergo an FDA review process.
And in lab studies, CBD has been shown to inhibit certain enzymes responsible for the metabolism of drugs, such as CYP2D6 and CYP3A4. This can affect how drugs work and affect our bodies, either by reducing their efficiency or making them more dangerous. This includes chemotherapy and other medications.
