Delta 9 Tetrahydrocannabinol
Delta-9-tetrahydrocannabinol (Δ9-THC) is the primary psychoactive cannabinoid in cannabis, produced in trichomes on flower and leaves. It binds to CB1 and CB2 receptors in the endocannabinoid system and is the most abundant cannabinoid in many modern cultivars. THC biosynthesis begins with cannabigerolic acid (CBGA) and proceeds through enzymatic pathways controlled by multiple genes, particularly THCA synthase. THC content varies dramatically across strains, seed genetics, growing conditions, and harvest timing. Understanding THC genetics is foundational for breeders selecting for specific cannabinoid profiles and phenotypic stability.

Breeders use THC content as a primary selection trait when developing new cultivars, targeting everything from trace amounts (<0.3%) in hemp cultivars to high-THC phenotypes in therapeutic research lines. Cannabinoid ratio inheritance involves multiple loci; breeders often cross for dominant THCA synthase expression while managing interactions with CBDA synthase genes that influence final THC-to-C
