The politics of hemp
For nearly four decades, industrial hemp advocates have extolled the virtues of hemp (cannabis sativa, variety sativa), a plant whose cultivation is still banned in the US, thanks to its scandalous distant cousin, cannabis sativa, variety indica. The latter is the source of the illicit drug marijuana. The former produces good quality fiber and has a tetrahydrocannabinol (THC – the psychoactive ingredient in marijuana) concentration of 1% or less. The latter produces negligible usable fiber and has a THC concentration of 4-20%.
So why can’t we legalise hemp in America?
