AIt has often been proposed that this type be recognized as a distinct species, ''C. indica''. Most recently, on the basis of recent genetic analysis, it has been proposed includedthat both the narrow-leaflet and wide-leaflet drug "biotypes" under ''C. indica'', as well as southern and eastern Asian hemp (fiber/seed) landraces and wild Himalayan populations, be recognized as a distinct species, ''C. indica''.<ref>Hillig, K.

Wide-leafed ''Cannabis indica'' plants in India, Afghanistan and Pakistan are traditionally cultivated for the production of hashish. Pharmacologically, the wide-leafed "indica" landraces tend to have a higher [[cannabidiol]] (CBD) content than "sativa" drug strains.<ref>Hillig, K. W., and P. G. Mahlberg. 2004. A chemotaxonomic analysis of cannabinoid variation in ''Cannabis'' (Cannabaceae). ''American Journal of Botany'' 91: 966-975.</ref> Most commercially available "indica" strains have been selected for low levels of CBD (which is not psychoactive), with some users reporting more of a "stoned" and less of a "high" effect from "indica" compared to "sativa". Differences in the terpenoid content of the essential oil may account for some of these differences in effect.<ref>McPartland J. M., and E. B. Russo. 2001.
