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.

History of Medical Cannabis in Sri Lanka (Weliange 2018)
"History of Medical Cannabis in Sri Lanka" is a conference abstract by Wasantha Sena Weliange, presented at the International Conference on Cannabis and Medicinal Research held in Osaka, Japan, on 15–16 November 2018 and published in the Journal of Neurology and Neurophysiology, Volume 9. The abstract catalogues approximately 20 Ayurvedic and indigenous medical texts from Sri Lanka that mention cannabis (Sinhala: කංසා, kansā; also ගංජා, ganjā), spanning from 341 AD to 1999.
The earliest entry is the Sarartha Sangrahaya (341 AD), a medical pharmacopoeia attributed to King Buddhadasa, followed by the medieval Yogarnavaya and Prayagorathnavaliya (both 1232) and the Vaidyacintamani (1707); twentieth-century entries include the official Sri Lankan Ayurvedic Pharmacopeia (1937) and the Desheeya Guli Kalka Sagaraya (1999). The tradition continues through the Ayurvedic Drug Corporation at Navinna, which produces named cannabis-based medicines under the Ayurveda Act No. 31 of 1961; in 2023 a total of 1,261.64 kg of cannabis was consumed for Ayurvedic medicinal purposes in Sri Lanka. read more →
