The FDA states that over 60% of the over the counter CBD products are contaminated or do not contain the listed amounts of CBD.
There are still gaps in knowledge regarding the sedative effects of CBD; the impacts of long-term exposure to CBD; CBD administration and the processes by which full spectrum and broad spectrum hemp extracts are derived, and how those products may compare to CBD isolate products.The FDA recently remarked,"we are aware of the risks posed by product contaminants such as heavy metals, THC or other potentially harmful substances. We also have significant concerns about products marketed with false claims or statements such as omitted ingredients."
