Shutterstock The lack of standardized third-party testing, and overall regulation, is often cited in reference to the blossoming hemp-derived cannabinoid market. While plenty of consumers will attest to the power behind these products and there are surely plenty of companies doing their due diligence, there is simply less oversight with hemp compared to the legal cannabis industry.

For this reason, consumers of some hemp-derived products may find themselves in the midst of a hefty psychoactive experience when they otherwise assume they are using a solely hemp or CBD offering.

A new study in the journal Forensic Chemistry sheds more light on the prevalence of THC in products advertised as hemp, which must contain less than 0.3% THC, per the 2018 Farm Bill , in order to be federally legal and considered hemp.

Researchers from the National Institute of Standards and Technology (NIST) and State University of New York (SUNY) Albany found that an overwhelming majority of smokable hemp products contained more than the aforementioned THC limit in a recent analysis.

This means that these products should actually be considered cannabis, not hemp, and that they are technically illegal on a federal level. A Closer Look at Smokable Products

The study analyzed 53 smokable hemp products from five commercial manufacturers, though specific products and manufacturers are unnamed. Researchers looked for the presence of a variety of cannabinoids including delta-8 THC, delta-9 THC, THC-A and total delta-9 THC.

Researchers took between 10 and 20 grams of each product, used a “small portable Magic Bullet grinder” and four to five pulses “to represent similar procedures forensic laboratories have been using to measure total Δ9-THC in seized cannabis plant samples.” They then utilized a methanol extraction procedure and proceeded to use the LC-PDA method, which separates 11 cannabinoids in less than 10 minutes.

“Over 90% of the samples analyzed by NIST were determined to have a total total Δ9-THC mass fraction above 0.3 % even though samples were being marketed as hemp,” researchers write. “Surprisingly, often the associated online documentation reported total Δ9-THC mass fractions of ≥0.3 %.”

Approximately 93% of the samples were above the 0.3% federal limit, […]
