Results showed that a 31 of the 40 products (77.5%) tested did not contain the amount of CBD claimed on the label.
Leafreport, a CBD educational platform, released a study evaluating the accuracy of CBD claims on topical products. Through a third-party testing lab, called Canalysis Laboratories (Las Vegas, NV) 40 CBD topical products from various popular and less-known CBD brands were evaluated. Results showed that a 31 of the 40 products (77.5%) did not contain the amount of CBD claimed on the label. In fact, only 9 of the products (22.5%) contained within 10% of the label claims. Eight of the product contained more CBD than stated, while one contained less.
The 31 CBD topicals that were not within 10% of CBD label claims diverged in varying degree. For example, 14 of the products contained within 20% of CBD claimed on the label. Of these 12 contained more than stated on the label, and two contained less. The worse 11 products diverged more than 30% from label claims. Of these, five products contained more CBD than stated on the label, and six contained less.
Leafreport found similar results when independently testing CBD beverages. Sample testing by FDA has also shown inconsistency, with the agency committing to a long-term sampling plan to determine the extent of adulteration in the market.
