Brief Description
THCP is a semi-synthetic cannabinoid categorized as a phytocannabinoid and is structurally similar to other phytocannabinoids (e.g., THC, CBD, CBDP). THCP is present at trace amounts in Cannabis sativa; however, drug products purportedly containing synthetically derived THCP have been sold online and in smoke shops in the form of plant materials, edibles, and vapes. THCP was first identified by our laboratory in May 2025 and confirmed after acquiring standard reference material.
