cbd tincture helps cancer

CBD comes from cannabis plants called hemp that are specifically grown with high levels of CBD and low levels of THC. Cannabis plants grown with high levels of THC are usually called marijuana. CBD comes from oil that is extracted from the cannabis plant. That oil can then be ingested as a liquid, a capsule, a gummy, or inhaled through vaping. It can also be added as an ingredient in such products as lotions and skin patches.

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.

What is CBD?

There is much about CBD that is still unknown. It has largely gone unstudied because, until 2018, it was considered a schedule I drug by the U.S. Drug Enforcement Administration (DEA). A schedule I drug is a drug that has been declared illegal by the DEA because of safety concerns over its potential for abuse and because there is no accepted medical use for it. Then, in September 2018, the DEA updated CBD’s status to become a schedule V drug. Schedule V drugs have a lower potential for abuse and are deemed to have some medical use.

It is also important to note that some studies have shown that CBD might interfere with how your body processes cancer drugs, called a drug interaction. This might make cancer treatments more toxic or make them less effective. More research is needed on these effects, too. For these reasons, always tell your oncologist if you’re thinking about using CBD before you take it.

To date, no large-scale studies have shown CBD to have benefits for the treatment of people with cancer. Most studies that have been done evaluating CBD as a cancer treatment were in mice or in human cells in the lab. For instance, there are some studies that have shown that CBD inhibits the growth of cancer cells in mice with lung cancer or colon cancer. Another study showed that CBD, together with THC, killed glioblastoma cancer cells in the lab. However, no studies have been conducted in people with cancer.

Dr. Raghunathan: It is possible that CBD could have a benefit with symptoms of anxiety, poor sleep, and pain. CBD has been studied a lot in the laboratory and in mice but far less in humans. Right now there are some studies that are evaluating CBD as a part of cancer treatment, but none of those have had significant results. The studies that do show a benefit with CBD are for specific epilepsy syndromes in children.

We asked Nirupa Raghunathan, an integrative medicine doctor at Memorial Sloan Kettering, and pharmacist Jason Hou, who manages MSK’s About Herbs database, to share what people with cancer should know before trying marijuana or its cousin, cannabidiol (CBD).

Dr. Raghunathan: Medical marijuana contains THC and that requires certification in states that allow for medical marijuana. In New York, people with cancer are allowed to use medical marijuana in the form of capsules, liquids, oils, powder, and patches for the skin. There is medical cannabis that can be vaped, but not medical-grade marijuana leaf that can be smoked. Medical marijuana providers must be registered with the New York State Department of Health’s Medical Marijuana Program. The restrictions in New York state are changing, but we don’t know how just yet.

How can people with cancer use CBD?

Dr. Raghunathan: The new law allows New Yorkers 21 and over to have up to three ounces of marijuana for recreational use. Using and selling marijuana are both legal, except in schools, workplaces, or in cars. The law also allows New Yorkers up to 24 grams of concentrated cannabis products, including products containing CBD, which is one of many chemicals extracted from the cannabis plant. CBD is different from delta-9-tetrahydrocannabinol, also known as THC, which is another chemical extracted from the cannabis plant.

Dr. Raghunathan: How CBD works is not fully understood, but it seems to work through a variety of pathways in the body that have different effects. For example, it seems to have an anti-inflammatory effect, which is helpful with pain. It also works on serotonin receptors, which helps with anxiety. Because CBD works in many ways, people should discuss it with a doctor. It is important to understand both the possible benefits and risks.

Cannabis, also known as marijuana, is used to treat some symptoms related to cancer. It’s made from the flowers, leaves, and resin (sticky chemical) of the Cannabis sativa plant.

The law also establishes retail licenses, opening the door for dispensaries selling marijuana online and in retail stores.
