Chromatogram of 12 cannabinoids for ACS Laboratory's "Potency 12" test. "ACS Laboratory's Potency 12 test is a completely different method from the industry standard because it specifically targets and separates Delta-8, Delta-9, and Delta-10 THC," said Aixia Sun, D.H.Sc., M.Sc., B.Sc., MT(AAB), ACS Laboratory Principal Scientist and Certified Cannabis Lab Director. "Many labs cannot test Delta-10 without a DEA license and often misidentify lesser-known analytes as Delta-9 in the process." Delta-9 is a Schedule I illicit substance that cannot exceed 0.3% in hemp products, while Delta-8 and Delta-10 THC remain unregulated and in high-demand. Delta-8 is becoming exceedingly popular due to its distinct psychoactive effects and ability to bind with different receptors, leaving a person feeling relaxed but not confused. Delta-10 offers euphoria and increased focus, without the paranoia some users report from Delta-9. Hemp companies are rapidly developing Delta-8 and Delta-10 THC extracts, which they're bottling or infusing into edibles.
