Most CBD Oils, Tinctures, Vapors Labeled Inaccurately

Only 31% of CBD (cannabidiol) extracts sold online were found to contain their listed amounts of CBD, according to research published this week in the Journal of the American Medical Association (Bonn-Miller, JAMA 2017). Forty-three percent of products contained less CBD than listed (often 1% or less) and 26% provided more. 

The products tested included 40 CBD oils, 20 tinctures, and 24 vaporization liquids. Only 12.5% of CBD vaporization liquids contained their listed amounts, as compared to 25% of the tinctures, and 45% of the CBD oils. 

THC (tetrahydrocannabinolic acid) was detected in 18 of the products. THC, a compound also found in cannabis, is typically not permitted in CBD products for medical use at a concentration of greater than 0.3%, yet was found in one product at a concentration of 6.43 mg/mL -- about 0.6%.

The researchers did not identify the specific products tested. However, ConsumerLab.com is currently testing products claiming to contain CBD and will be publishing findings for each product on ConsumerLab.com in coming weeks.
