Documentation of the traditional use of hallucinogens in Africa has lagged behind that of such use in the Americas, so the use of "Datura metel" 'Fastuosa' by the Tsonga people (Shangana-Tsonga) of Mozambique and the Northern Transvaal in their "khomba" puberty school initiation rite - as recorded by Dr. Thomas F. Johnston - is of particular interest. (Johnston incorporated some of his material on the "khomba" initiation into a PhD dissertation submitted to the University of the Witwatersrand).
