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 District Gazetteers: Pabna (1923)
The Bengal District Gazetteers: Pabna is a district gazetteer compiled by the Indian Civil Service officer L. S. S. O'Malley and published at Calcutta in 1923. It is one of the volumes of the Bengal District Gazetteers, the standardised provincial reference series issued under the authority of the Government of Bengal. The volume describes the district of Pabna, which the gazetteer dates as a separate charge from 1828; the district lay in the Rajshahi Division of Bengal Presidency at the time of writing and today forms part of Bangladesh.
The gazetteer records cannabis on the revenue and consumption side. Its chapter on General Administration carries an excise subsection setting out the district's ganja revenue for 1919–20, in which the duty and licence fees on hemp drugs out-earned those on country spirits (pp. 95–96), and its agricultural statistics return sunn hemp, the fibre legume, among the district's crops. read more →
