We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge—preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.

Cannabis in Khmer culture
Cannabis in Khmer culture covers the place of cannabis (Khmer: កញ្ឆា, kanhchhā) in Cambodian society. The plant has long served as a culinary herb, a household remedy and an occasional recreational substance, with meanings that have shifted significantly under twentieth-century drug policy, the Khmer Rouge period, post-conflict reconstruction and the eradication campaigns that have run intermittently since 1996 and intensively since 2017.
Two dedicated articles cover the culinary and medicinal threads in detail: Cannabis in Khmer Cuisine and Cannabis in Khmer Medicine. This page is the cultural overview that situates them and traces the recent shifts in tolerance, enforcement and market structure that bear on traditional use. read more →
