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: Santal Parganas (1910)
The Bengal District Gazetteers: Santal Parganas is a district gazetteer compiled by the Indian Civil Service officer L. S. S. O'Malley and published at Calcutta in 1910. It is the twenty-second volume of the Bengal District Gazetteers, the standardised provincial reference series issued under the authority of the Government of Bengal. The volume describes the Santal Parganas, a district constituted in 1855 in the aftermath of the Santal Hul and administered as a non-regulation district; the territory lay in the Bhagalpur Division of Bengal Presidency at the time of writing, passed to the new province of Bihar and Orissa in 1912 and today forms part of Jharkhand.
The gazetteer is not a cultivation source in the manner of the lowland Bengal ganja surveys. Its cannabis-relevant content is confined to three passages: the chapter on The Santals records the use of ganja by the Sapha Har, a Santal religious-reform sect (pp. 150–151); the chapter on General Administration tabulates the district's ganja excise (p. 235); and the agricultural statistics return acreage under "hemp" (pp. 165–166) without identifying the plant. The ethnographic chapters draw substantially on field notes contributed by the Norwegian missionary P. O. Bodding, whose monograph on Santal medicine separately documents the medicinal and ritual cannabis use of the community. read more →
