A study published in Cannabis and Cannabinoid Research assessed the label accuracy and content of various hemp-derived cannabidiol (CBD) products and advertised claims on product labels. These products included hemp-infused cosmetics, haircare, and food and drink products from retailers in the Baltimore, Maryland area.
The researchers used gas chromatography–mass spectrometry to calculate the percent deviations between labeled and actual CBD concentrations. The team then quantified the references to the Food and Drug Administration (FDA), external testing claims, and other claims (cosmetic or beauty improvements, therapeutic effects, health halo effect, or “other”).
The researchers purchased 97 products (35 purchased in-store and 62 purchased online). They noted that 49% of 71 products included a specific total CBD amount on the label. 35 products (49%) were underlabeled (>10% more CBD than advertised). 27 (38%) products were overlabeled (>10% less CBD than advertised). Only 9 products (12.7%) were accurately labeled (within ±10% of labeled CBD).
24% of the 97 (total) products had labels that featured a cosmetic or beauty claim (for example, “skin looks more youthful”). 40% of the products had a label with a therapeutic claim, such as pain relief. 86% included a health halo effect claim (“paraben-free,” “dye-free,” etc.). Most products (63%) did not include a disclaimer that health claims had not been evaluated by the FDA.
The researchers described most products included in the sample as inaccurately labeled for CBD content. This was true even when the labels referenced a third-party laboratory product review. Analysis showed that 10 products contain no CBD at all. Many product labels featured therapeutic claims or marketing strategies that suggested they were safe, but most did not include disclaimers (that the FDA did not review the statement).
These findings emphasize the importance of rigorous regulatory oversight of cannabinoid product content and quality to prevent consumers from receiving misleading information. More stringent regulations will promote better quality assurance and safety procedures.
