Question: Are hemp-derived topical cannabinoid products available online and at national retailers accurately labeled for cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) content?

Findings: In a case series of 105 topical cannabinoid products, 18% were overlabeled (>10% less CBD than advertised), 58% were underlabeled (>10% more CBD than advertised), and 24% were accurately labeled for CBD; THC was detected in 35% of products (all contained less than 0.3% THC, the legal limit for hemp). Products often made therapeutic or cosmetic claims.

Meaning: These findings suggest that improved regulatory oversight of cannabis and hemp products is needed to ensure quality assurance, deter misleading health claims, and potentially prevent unwanted drug effects among consumers.
