Drug Type Cultivars

"Drug type" is a historical classification referring to cannabis cultivars bred primarily for cannabinoid content rather than fiber or seed production. The term emerged from early taxonomic efforts to distinguish high-resin plants from hemp varieties, though modern breeding has largely superseded this categorical language. Drug-type cultivars typically exhibit compact flowering structures, dense trichome coverage, and selection for cannabinoid accumulation. Breeders working in contemporary markets use more specific descriptors—such as THC-dominant, CBD-dominant, or balanced ratios—rather than the umbrella "drug type" designation. Understanding this lineage classification helps contextualize older breeding records and cannabis research literature from the late 20th century.

Historical drug-type breeding focused selection pressure on resin production and flowering potency, establishing foundational lines still present in modern genetics. Contemporary breeders reference drug-type ancestry when tracing cannabinoid expression and trichome density traits in pedigrees.
