Featured Accessions
🔴 Critical • Northeastern Thailand
Legendary landrace sativa known to many as 'Thai Sticks', grown in the Phu Phan hills of Sakhon Nakhon province in Northeastern Thailand. Famed for soaring cerebral effects and traditional bamboo stick curing. Facing extreme pressure from hybrid contamination and changing cultivation practices.
🟠 Endangered • Northern Afghanistan
Heavy indica from Afghanistan's historic hash-making region. Dense, resinous buds with sedating effects. Population declining due to ongoing regional conflicts and security issues.
🟡 Vulnerable • Himachal Pradesh, India
Sacred variety from the isolated village of Malana, traditionally used for high-grade charas production. Facing extinction from tourism pressure and commercialization.
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.

Ganja Society
Ganja Society, formally the Naogaon Ganja Cultivators' Co-operative Society Ltd (Bengali: নওগাঁ গাঁজা চাষি সমবায় সমিতি লিমিটেড), was the growers' cooperative that held the licensed ganja monopoly of the Ganja Mahal, the Bengal Presidency's sole permitted cannabis-cultivation tract, from its registration in 1917 until the prohibition of cultivation in 1987. Formed when the Naogaon cultivators collectively withdrew their cultivation licences in 1916, the society took over the purchasing, grading, warehousing and sale of ganja that had until then been managed through licensed brokers under direct Excise Department supervision, the member-cultivators thereby holding the monopoly collectively.
The society was based at Naogaon, in what is now north-western Bangladesh. Its relationship to present-day West Bengal follows that of the Ganja Mahal itself: the cultivation tract and the cooperative both lay in the territory that became East Pakistan in 1947, while the downstream consumption markets and the wholesale and retail trade remained with West Bengal and Calcutta. The cooperative outlasted the end of cultivation and continued in a reduced, custodial form into the twenty-first century. read more →
