The analysis included 105 products purchased from retail outlets and online businesses.
The researchers found that of the 89 products that listed a full amount of CBD on the label, 16 products were over-labeled (eg, contained >10% less CBD than advertised), 52 products were under-labeled ( for example, contained >10% more CBD than advertised), and 21 products were accurately labeled. For in-store products, the median percentage difference between the actual total amount of CBD and the labeled amount was 21%, compared to 10% for online products. In more than a third of the products (35%), THC was detected, although all contained less than 0.3% THC (the legal limit for hemp). Of the 37 products containing THC, four were labeled as THC-free, 14 stated that they contained
