CBD is a cannabinoid that may relieve pain, lower inflammation and decrease anxiety without the psychoactive ‘high’ effect of THC.
Researchers are looking into Sativex as a treatment for cancer related symptoms.
CBD oil, cannabis oil and hemp oil
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.
A drug called dexanabinol which is a man made form of a chemical similar to that found in cannabis has been trialled in a phase 1 trial. This is an early trial that tries to work out whether or not the drug works in humans, what the correct dose is and what the side effects might be. The results are not available yet. You can read about the trial on our clinical trials database.
You could talk with your cancer specialist about the possibility of joining a clinical trial. Trials can give access to new drugs in a safe and monitored environment.
This is difficult to answer, as research into cannabis and the chemicals in cannabis is still in its infancy. Most of the research so far has involved work in cells and mice. THC and CBD are two of the main cannabinoids found in the cannabis plant.
Some cannabinoids inhibit the growth of tumour cells in test tubes and mice, but others encourage growth. Human studies are still small and hard to come by.
There is no evidence that CBD oil can be used to treat cancer in people. CBD does show promise for the management of some cancer related symptoms, including pain and anxiety, however, more research into appropriate amounts of CBD and its effects on humans is necessary.
Does CBD oil offer any medical benefits?
This is why research and regulated clinical trials are so important. They enable us to make informed decisions on what treatments are likely to work best based on solid evidence.
Relatively. The doses sold in UK health stores are generally too low to cause any serious harm. Side effects of CBD include nausea, fatigue and diarrhoea. Most importantly, it can affect certain medications and you should always check with your GP before trying CBD oil. Because CBD oil is freely available to purchase in stores, it is not as tightly regulated as medicines.
One study of cannabis users found they had a lower risk of bladder cancer, but their risk of developing prostate cancer increased.
There is some evidence that CBD oil could be effective against some rare childhood epilepsies. But again, more data is needed before we can draw any firm conclusions. Studies also show that CBD oil could be beneficial for managing anxiety and insomnia in some people, and early research also suggests a possible use of CBD for the treatment of certain types of pain.
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.
There are 2 synthetic cannabis medications, nabilone (Cesamet) and dronabinol (Marinol or Syndros), that are FDA-approved to treat nausea and vomiting related to chemotherapy. These medications are made in a laboratory.
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.
Can CBD help people with 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.
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.
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.
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.
