Regardless of opinions on legalization, many people accept the idea that medical marijuana, and more specifically CBD, can be a powerful treatment for many medical conditions. However, there has been one major roadblock: the FDA. According to the FDA, more than 90 warning letters over the past 10 years have been released to companies claiming that their cannabis products cure various symptoms. The most common is the claim that marijuana prevents or treats cancer. In 2017, as the medical properties of marijuana continue to be trumpeted to the general public, the FDA is still working to protect the public by issuing warning letters to marijuana providers making unsubstantiated claims.
