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.
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.
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.
Can CBD help people with cancer?
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.
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.
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.
For Mathias Schmucki, finding a company that provided a COA with all this information was a must. She says there are several online companies that send it with every product. “The companies with the best reputations will often have very robust websites with educational resources,” she says, so look for these.
“I tell my doctors that I’m not holding them responsible for my decision to use CBD, but I want them to know this is a choice I’m making,” Mathias Schmucki says. “I’m giving them information they need to provide the best care that they can.”
“There’s a lot of information out there, but I think you really have to be careful about where you get that information,” Mathias Schmucki says. She advises looking to see if your local medical center has an integrative oncology department that includes nontraditional therapy like CBD and can give you guidance. Other good resources include pharmacists trained in cannabis, experts at medical cannabis dispensaries, and pain management doctors, Weiss says.
Talking to Your Doctor

Weiss notes that there are all kinds of CBD products beyond oil, such as edibles, capsules, tinctures, creams and oils for skin, and sprays that you can use under your tongue.
