Abstract
Dagga (Cannabis sativa L.) samples were collected from various geographical regions of South Africa. These were classified into age, sex and plant part and the cannabinoids were analysed quantitatively by gas-liquid chromatography and mass spectrometry. Analytical results show that there appears to be at least three chemovariants of Cannabis sativa growing in South Africa with respect to relative cannabinoid content. One of these variants appears to be unique to Southern Africa. It also appears that South African C. sativa ranks among the world's more potent C. sativa variants in terms of its Δ9 -tetrahydrocannabinol content.
