Nabilone is a drug developed from cannabis. It is licensed for treating severe sickness from chemotherapy that is not controlled by other anti sickness drugs. It is a capsule that you swallow whole.
Research into cannabinoids and cancer
We need more research to know if cannabis or the chemicals in it can treat cancer.
A cannabis based medicine, Nabilone, is a treatment for nausea and vomiting.
Researchers are looking into Sativex as a treatment for cancer related symptoms.
CBD oil comes from the flowers of the cannabis plant and does not contain the psychoactive substance THC. It can be sold in the UK as a food supplement but not as a medicine. There is no evidence to support its use as a medicine.
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.
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.
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.
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.
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.
Yet there’s very little research around CBD and its use in treating people with cancer. Here’s what to know about what CBD is and what science currently shows about whether it’s safe and effective for people with cancer to use.
Occurring in an artificial environment (such as a lab) outside of the body. In vitro is Latin for in glass (as in a test tube).
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
Cannabis comes from the cannabis plant. The main psychoactive ingredient in cannabis is THC (delta-9-tetrahydrocannabinol). THC is a type of cannabinoid.

Some people believe that cannabis can help control or relieve some of the symptoms of cancer or the side effects of cancer treatments. But research studies done so far do not give a clear answer about the effectiveness of smoking cannabis. Research does show that some cannabinoids can help with some symptoms and side effects, and drugs containing cannabinoids have been developed to treat pain, nausea and vomiting.
Some people claim that cannabis can help relieve long-term (chronic) or severe pain. Research studies done so far do not give a clear answer about the effectiveness of cannabis to relieve pain.
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.
