An interesting article titled "Entheogens of Africa" in Issue 2 Volume 3 of the Dragibus magazine lists a number of plant species that are used as "cannabis substitutes" (i.e. mixed with tobacco and smoked). These species and the parts used are: Cineraria aspera (?) Cullen obtusifolia (leaves and stems) Sutherlandia frutescens (seeds and leaves) Nenax microphylla (seed) Apart from the medicinal use of Sutherlandia frutescens (Wikipedia: An infusion made from the leaves is a traditional remedy for fever, chicken pox, flu, rheumatism, hemorrhoids, diarrhea, and stomach and liver problems), there doesn't appear to be much ethnobotanical information online about these plants. Does anyone have any experience with growing or using them? Cheers, ∂an
