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.

Bengal Presidency cannabis trade
Bengal Presidency cannabis trade refers to the licensed, excise-regulated commerce in cannabis preparations - ganja, bhang and charas - across the Bengal Presidency under East India Company and Crown rule, from the consolidation of Company authority in the late eighteenth century to Partition in 1947. From the 1790s the colonial state taxed cannabis through a licensing system inherited from Mughal-era *abkari* (excise) practice, and over the nineteenth century it confined licensed cultivation to a single small tract in northern Bengal, the Ganja Mahal around Naogaon, while the manufactured product was distributed and consumed across the Presidency and beyond.
The trade was built on a graduated excise duty levied at the point of issue from licensed warehouses, on a small body of wholesale dealers who carried the drug under transport permit, and on a network of licensed retail shops. It was examined in detail by the Indian Hemp Drugs Commission of 1893–94, which rejected prohibition and recommended that the Bengal model of confined cultivation, warehouse monopoly and high duty be extended to the other provinces of British India. Although it generated significant revenue, the cannabis trade was always far smaller than the opium trade that dominated colonial fiscal policy in Bengal. … read more →
