National Wastewater Surveillance of Illicit Tobacco and Vaping Use Trends in Australia

Following recent tobacco control policies, what are the trends in smoking and vaping in Australia?In this cross-sectional study, with wastewater samples representing up to 50% of the Australian population, a continued decline in tobacco use was observed, particularly in regional areas. However, the results also suggested a recent increase in nicotine consumption primarily sourced from vaping products as well as an expansion of the illicit tobacco market in Australia.This study found that tobacco use has decreased in Australia; however, the rise in illicit tobacco and vaping underscores the need for additional measures to maintain progress in tobacco control.
