Labeling Accuracy of Cannabidiol (CBD) Extracts Sold Online
With the growing use of cannabidiol (CBD), this article might be of interest. Because of discrepancies between federal and state cannabis laws, there is inadequate regulation and oversight, leading to the inaccurate labeling of some products. This article examines the labeling accuracy of CBD sold online and includes identification of present but unlabeled cannabinoids.
Eighty-four products (from 31 companies) were purchased and analyzed for CBD concentration
18 of 40 oil products were within 10% labeled concentration
5 of 20 tinctures were within 10% labeled concentration
3 of 24 vaporization liquids were within 10% labeled concentration
Deviation from labeled content (Mean % of deviation)
Oil – 29%
Tinctures – 220.62%
Vaporization liquids – 1099% (yes, that is one-thousand)
Concentration of unlabeled cannabinoids was generally low
THC was detected (up to 6.43 mg/mL) in 18 of the 84 samples tested
Cannabidiolic acid (up to 55.73 mg/mL) in 13 of the 84 samples tested
Cannabigerol (up to 4.67 mg/mL) in 2 of the 84 samples tested
