Pituri is a mixture of wood ash and leaves traditionally chewed as a stimulant (or, after extended use, a depressant) by Aboriginal Australians widely across the continent. Leaves are gathered from any of several species of native tobacco ( Nicotiana), or from at least one distinct population of the species Duboisia hopwoodii. Various species of Acacia, Grevillea and Eucalyptus are burned to produce the ash. The term may also refer to the plants from which the leaves are gathered or from which the ash is made. Some authors use the term "pituri" to refer only to the plant Duboisia hopwoodii and its leaves and any chewing mixture containing its leaves.

Seeing that still she did not quite understand, the black boy opened his Acan jerkin and showed her lying upon his chest, which was most hideously wealed, a little bag that he had made himself out of opossum fur,--the kind of bag that is recognised at once among aboriginal tribes as containing the precious pituri, and the possession of which ensures safety to its bearer, no matter how hostile the people among whom he travels.
But there was a chance that they might not drink the drugged tea--that the pituri might not act as was intended.
