“…The leaves contain a range of toxic chemicals, including carcinogenic nitrosamines that are potentially detrimental 6,9,23 . Furthermore, the ash and its addition to the quid produce changes to the ionic base with the possibility of other compounds being produced from the mixing process.…”

Introduction: Tobacco smoking has a range of known and predictable adverse outcomes, and across the world sustained smoking reduction campaigns are targeted towards reducing individual and public risk and harm. Conversely, more than 87 million women, mostly in low-and middle-income countries, use smokeless tobacco, yet the research examining the effect of this form of tobacco exposure on women is remarkably scant. In central Australia, the chewing of wild Nicotiana spp., a tobacco plant, commonly known as pituri and mingkulpa, is practised by Aboriginal groups across a broad geographical area. Until recently, there had been no health research conducted on the effects of chewing pituri. Methods: This article reports on one component of a multidimensional pituri research agenda. A narrative approach utilising the methodology of the Learning Circle was used to interview three key senior central Australian Aboriginal women representative of three large geographical language groupings. The participants were selected by a regional Aboriginal women's organisation. With the assistance of interpreters, a semistructured interview, and specific trigger resources, participants provided responses to enable an understanding of the women's ethnobotanical pituri knowledge and practices around the use of pituri within the context of Aboriginal women's lives. Data were transcribed, and by using a constant comparison analysis, emergent themes were categorised. The draft findings and manuscript were translated into the participants' language and validated by the participants. KJ Steadman, 2017.

The findings demonstrated similar participant ethnobotanical knowledge and practices across the geographical area. The participants clearly articulated the ethnopharmacological knowledge associated with mixing pituri with wood ash to facilitate the extraction of nicotine from Nicotiana spp., the results of which were biochemically verified. The participants catalogued the pleasurable and desired effects obtained from pituri use, the miscellaneous uses of pituri, as well as the adverse effects of pituri overdose and toxicity, the catalogue of which matched those of nicotine. The participants' overarching pituri theme was related to the inherent role pituri has in the connectiveness of people to family, friends and community. Conclusions: Central Australian Aboriginal women have a firmly established knowledge and understanding of the pharmacological principles related to the content of Nicotiana spp. and the extraction of nicotine from the plant. Widespread use of Nicotiana spp. as a chewing tobacco by Aboriginal populations in the southern, central and western desert regions of Australia is attested to by participants who assert that everyone uses it, with girls in these remote areas c...
