Why the Popular Hemp Test Is the Wrong Hemp Test

In this video, cannabis attorney Rod Kight explains why hemp testing methods are critically important to the legality of hemp products and argues that one of the industry’s most commonly used testing methods may produce misleading results.

Rod discusses the legal distinction between hemp and marijuana under federal law, which is based primarily on Delta-9 THC concentration. Hemp containing 0.3% Delta-9 THC or less is considered lawful, while cannabis exceeding that threshold is classified as marijuana.

The video focuses on two testing methods used in the hemp industry: gas chromatography and high-performance liquid chromatography (HPLC). Rod explains that gas chromatography heats hemp samples during testing, which can chemically convert non-psychoactive THC-A into Delta-9 THC. According to Rod, this process artificially creates the very compound being measured and can distort the true THC concentration of the plant.

He argues that HPLC testing is more accurate because it measures cannabinoid compounds without heating the sample, allowing laboratories to distinguish between THC-A and Delta-9 THC without chemically altering the material.
