Independent testing reveals that many commercially marketed CBD-infused products contain lower percentages of cannabidiol than are advertised on the products’ label, according to an investigation conducted by NBC News in Miami.
Investigators submitted 35 commercially available products for third-party independent lab testing. “Of the 35 samples … tested, 20 of them had less than half of the amounts of CBD advertised on the label,” NBC reported. Some samples, such as a package of infused gummies claiming to contain 1,000 mg of CBD, contained no cannabidiol.
The NBC findings are consistent with those of prior studies — such as those here, here, here, and here — which similarly reported that many CBD-infused products are of variable potency. Another recent study identified the presence of the psychoactive adulterants DXM and 5F-ADM in a line of products marketed by the manufacturer Diamond CBD.
By contrast, recent third-party testing of a sampling of 29 leading CBD-infused products by Remedy Review reported that all but one product tested positive for the presence of CBD at levels similar to what was advertised. However, three of the products did test positive for the presence of either pesticides or fungicides. “These results … indicate the need for independent monitoring and testing,” the company stated in a press release.
