Over-the-Counter CBD Products Typically Less Potent Than Advertised

Oxford, MS: Many CBD-infused products available over-the-counter contain far lower percentages of cannabidiol than advertised on the products’ labeling, according to findings published in the Journal of Dietary Supplements.

A team of investigators from the University of Mississippi lab-tested 25 commercially available hemp/CBD oil products. These commercially available products are not regulated by the US Food and Drug Administration.

Of the 25 products tested, 15 possessed quantities of CBD that were far below what was advertised on the products’ labels. Three of the products tested positive for levels of THC above the federal 0.3 percent limit. In four of the products tested, investigators identified the presence of synthetic cannabinoid adulterants.

Authors concluded: “From this small, but diverse sampling of hemp-derived merchandise, it appears that most product label claims do not accurately reflect actual CBD content and are fraudulent in that regard. … These findings argue strongly for further development of current good manufacturing practices for CBD-containing products and their stringent enforcement.”

The study’s findings are consistent with dozens of other analyses reporting that commercially available CBD products are of heterogeneous quality – with many containing psychoactive adulterants, heavy metals, and lower than advertised percentages of cannabidiol,

According to a newly released marketing report by New Frontier Data, an estimated 18 percent of Americans over the age of 18 have tried CBD products, with many acquiring them from online sources.
