Results have shown that different cannabinoids can:
Different types of cannabis have differing amounts of these and other chemicals in them. This means they can have different effects on the body.
In 2021, scientists reported the final results of a phase 1 study to treat people with recurrent glioblastoma (a type of brain tumour that has come back). The study looked at Sativex in combination with the chemotherapy drug temozolomide.
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.
Why people with cancer use it
Scientists also discovered that cannabinoids can:
Does CBD oil have any side effects?
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.
State laws vary. In Texas, the Compassionate Use Act allows for the use of medical marijuana for certain conditions. Originally only for intractable epilepsy, the law was expanded this year to include cancer and certain neurodegenerative conditions, such as Parkinson’s and multiple sclerosis.
There have been reports that cannabinoids like THC and CBD may be helpful for nausea and vomiting and anorexia, as well as neuropathy, anxiety, depression and insomnia. Synthetic cannabinoids like dronabinol have been approved for use with chemotherapy-induced nausea and vomiting, but have not been shown to be superior to conventional anti-nausea medications.
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.
Have any CBD-oil derived products been approved by the U.S. Food and Drug Administration (FDA) to treat cancer, its symptoms, or the side effects caused by its treatment?
What is CBD oil, and how does it differ from marijuana and hemp?
But what is CBD oil exactly, and how does it affect cancer patients? Can it really treat — or even cure — cancer or relieve its symptoms? To separate fact from fiction, we spoke with our Kimberson Tanco, M.D. Here’s what he wants cancer patients to know.
