Yes, Drug Testing Methods Can Mistake Hemp-Derived CBD for THC
I recently came across a little-known study published in the Journal of Analytical Toxicology that raises serious questions regarding whether the gold standard in forensic urine testing could mistake hemp-derived CBD for THC. Many laboratories include derivatization as a part of their sample preparation for analysis by gas chromatography – mass spectroscopy (GC-MS). Derivatization is the process by which a compound is changed chemically so that it has properties that are more amenable to a particular analytical method. Essentially, the new compound becomes more suitable for detection and analysis. Researchers discovered trifluoracetic anhydride (TFAA), a common derivatizing agent used in GC-MS […]
