Sativa

Sativa is a vernacular and commercial label applied in modern cannabis markets to cultivars marketed as energizing, cerebral, and euphoric, typically described as tall, lanky, late-flowering plants with narrow leaflets — hence the proposed formal descriptor NLD ("narrow-leaflet drug"; Clarke & Merlin 2013). The term derives from Latin sativus ("cultivated, sown"), originally coined by Linnaeus (1753) to denote the cultivated hemp plant — a fiber and seed crop, not a psychoactive drug. The modern consumer meaning has diverged dramatically from the Linnaean taxon. Peer-reviewed genomic studies show that commercial "Sativa" and "Indica" labels do not map to genome-wide ancestry: Sawler et al. (2015) found only a moderate correlation between reported Sativa/Indica ancestry and SNP structure, while Watts et al. (2021), genotyping 137 drug-type plants at 116,000 SNPs, concluded the labels were "genetically indistinct on a genome-wide scale," driven instead by a few terpene synthase genes on chromosomes 5 and 6. McPartland (2018) and Piomelli & Russo (2016) argue the vernacular usage is taxonomically invalid. ⚠️ Disputed: commercial folk taxonomy vs. botanical nomenclature. → See also: Terpene Profile (Chemistry), Strain (Industry/Slang), Entourage Effect (Medical).
