Refinery 29, “a modern woman’s destination for how to live a stylish, well-rounded life,” recently reviewed the evidence on the benefits of cannabidiol (CBD) in cancer patients. While the amount of research on cannabis is minimal, there’s even less for CBD. But studies have found it reduces nausea and vomiting caused by chemotherapy compared to placebo, according to the National Cancer Institute. 

A few studies have also found CBD may slow the growth of certain kinds of cancers, including breast cancer, and reduce the risk of recurrence. CBD is also known to increase the potency of certain medications, possibly making it a helpful addition to chemotherapy and chemopreventive treatments.  The American Cancer Society has called for more research into the benefits of cannabis in cancer treatment.
