Mayo Clinic: CBD oils may be helpful, but more research is needed

Too few published clinical studies exist on the safety and effectiveness of cannabidiol oils at this time.

ROCHESTER, Minn. — Mayo Clinic Proceedings will publish a paper in September showing a growing body of pre-clinical and clinical evidence that CBD oils may be effective in treating conditions like chronic pain and opioid abuse. However, due to the lack of testing done on humans, Mayo Clinic researchers say more testing is needed before CBD oils are declared helpful and safe. 

"There are many intriguing findings in pre-clinical studies that suggest CBD and hemp oil have anti-inflammatory effects and may be helpful with improving sleep and anxiety," says Brent Bauer, M.D., an internist and director of research for the Mayo Clinic Integrative Medicine program. "But trials in humans are still limited, so it is too early to be definitive about efficacy and safety."

One of the concerns is CBD and hemp oil products are not regulated by the FDA. Consumers buying oral or topical oils, creams, sprays and tablets are buying products with varying amounts of CBD, and the products may also contain other active compounds. 

State laws vary regarding production and distribution of CBD and hemp products, which adds to the complexity of research, and affects both doctors and consumers. 

The Mayo Clinic advises that you talk to your doctor about possible side effects and the way CBD could interact with other medications, before using any form of cannabidiol.
