“Discrepancies between federal and state cannabis laws have resulted in inadequate regulation and oversight, leading to inaccurate labeling of some products, [Journal of American Medical Association].2
“To maximize sampling and ensure representativeness of available products, Bonn-Miller et al examined the label accuracy of CBD products sold online, including identification of present but unlabeled cannabinoids.
‘There is growing consumer demand for cannabidiol (CBD), a constituent of the cannabis plant, due to its purported medicinal benefits for myriad health conditions.1 Viscous plant-derived extracts, suspended in oil, alcohol (tincture), or vaporization liquid, represent most of the retail market for CBD.

Cannabidiol is a compound in marijuana that can provide medicinal benefits. A new study finds that only 1/3 of CBD products sold online are accurately labeled
(CNN)Medical marijuana is now legal in 29 states and the District of Columbia. But the law is not quite as black and white regarding marijuana extracts such as cannabidiol. CBD is one of the active ingredients in cannabis, increasingly thought to offer wide-ranging health benefits, with few side effects and little risk of addiction or abuse.
“More and more evidence is coming out that CBD can be helpful for a variety of conditions, from anxiety to inflammation to seizures and epilepsy,” said Marcel Bonn-Miller, an adjunct assistant professor of psychology in psychiatry at the University of Pennsylvania.
Even though medical marijuana is legal in more than half of US states, it remains illegal under federal law. As a result, the Food and Drug Administration does not regulate derivatives of the plant, including CBD extracts.
For a study published today in the Journal of the American Medical Association, Bonn-Miller and his team bought 84 commercially available CBD products on the internet and had them chemically analyzed by an independent lab.
The researchers found that only 31% of the products tested contained the precise amount of CBD advertised on the label (within the acceptable margin of error), while 26% contained less CBD than the label indicated and 43% contained more.
Accuracy of labeling, it turned out, was also associated with product type. About half of the CBD extract oils were labeled inaccurately. Nearly 90% of the vaporization liquids were labeled inaccurately. Tinctures (alcoholic extracts) were roughly equally likely to be over-, under- or accurately labeled.
THC, or tetrahydrocannabinol, has its own medical applications but, unlike CBD, is psychoactive and can cause a “high.”
Dr. Sanjay Gupta: Why I changed my mind on weed
“As things stand now, the supplement industry overall is not regulated,” CNN Chief Medical Correspondent Dr. Sanjay Gupta said. “You don’t always know what you’re getting, how much you’re getting or even if the active ingredients are in there at all. With medical marijuana, it is almost the opposite situation at the federal level. It is highly regulated.”
Bonn-Miller said increased regulation is exactly the kind of change he hopes his study will initiate.
Until these products are officially regulated, it’s buyer beware.
Unless you’re fully confident in the ingredients of the product, Bonn-Miller suggests following the adage “start low, go slow” — referring to dosage. Of course, your best bet is to always talk to your doctor before starting or stopping any medications or supplements, including CBD.<” Please see reference for completer report.
