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.
You may also be wondering if CBD is legal in your area. Some states allow the sale and possession of cannabis, including CBD and THC, for medical and recreational use. Others have stricter regulations, so state-by-state laws should always be learned before transporting CBD across state lines. Things are more complicated at the federal level. In 2018, the U.S. government recognized that hemp can be grown and manufactured legally as part of the Farm Act. Hemp can be used to make things like rope and clothing, in addition to CBD oil. In other words, hemp is no longer a controlled substance, which means it is not regulated by the government. This means that consumers have to evaluate the safety and quality of CBD products on their own. Some CBD, for example, may have much higher levels of THC than what is labeled.
There is currently 1 CBD treatment approved by the U.S. Food and Drug Administration (FDA) called Epidiolex, which is used to treat a rare and severe form of epilepsy in children. There are not currently any FDA-approved CBD medications for treating cancer or side effects of cancer treatments.
Can CBD help people with cancer?
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.
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.
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 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.
Sativex is a combination of delta-9-THC (Tetranabinex) and cannabidiol (Nabidiolex). It has been approved for use in Canada as a spray that can be applied to the cheek inside the mouth. Savitex may be used to relieve pain from advanced cancer that can’t be relieved with the strongest dose of opioids.
Nabilone (Cesamet) is a pill that has synthetic cannabinoids. It is approved in Canada to treat nausea and vomiting caused by chemotherapy. It’s sometimes given to people with cancer if standard antinausea drugs do not help relieve these symptoms.
The brain receives messages (electrical signals) from nerves in the spinal cord and cranial nerves. The nerves in the spinal cord carry messages between the brain and the body.

People who want to use cannabis for medical purposes must get a medical document (like a prescription) from a doctor or nurse practitioner. With this document, they can purchase cannabis for medical purposes through licensed producers in Canada. It comes in many forms including dried cannabis, cannabis oil, or fresh cannabis buds or leaves that can be smoked, vaporized, or eaten in food
Several studies have shown that some cannabinoids can relieve nausea, vomiting or both. These are side effects of some cancer treatments, including chemotherapy and radiation therapy.
Researchers are also still trying to find out if cannabis or cannabinoids should be used as medicine to treat certain diseases, including cancer. Research into the effects of cannabinoids on cancer cells in vitro and on experimental animals has shown some promise. But this research is still in the very early stages. Much more study is needed before cannabis or cannabinoids can be used as a cancer treatment.
