Dr. Rik Musty, the first U.S. researcher to investigate CBD, alerted us to this item posted on the US Food and Drug Administration website, March 3, 2015:
Warning Letters and Test Results
In late February 2015, FDA issued several warning letters to firms that market unapproved drugs for the diagnosis, cure, mitigation, treatment, or prevention of diseases. Some of these firms claim that their products contain cannabidiol (CBD). FDA has tested those products and, in some of them, did not detect any CBD. It is important to note that these products are not approved by FDA for the diagnosis, cure, mitigation, treatment, or prevention of any disease, and often they do not even contain the ingredients found on the label. Consumers should beware purchasing and using any such products.
The FDA site provides links to the Warning Letters and shows test results for the CBD-related products:
Musty is trying to learn more about what the federal government knows about CBD.
