A cursory glance over retailers’ shelves in Australia reveals a proliferation of imports, with locally‐made goods often a minority. This is especially true of clothing, footwear and small electrical appliances and is linked to lower tariffs and other barriers to trade. Much of the debate about government policy concerns the pace of tariff reform that will give domestic manufacturers a chance to adapt. Looks at the ways a small sample of companies has coped; many have moved production offshore. Analyses why, how, and through what strategies and environmental factors the rest keep on manufacturing here. Finally, compares the results with expectations.

Nicotine is consumed by one in five of the global adult population, mostly by smoking tobacco cigarettes. Modern electronic cigarettes came onto the market from around 2007 and have considerable potential to improve population health by displacing tobacco smoking. The purpose of this study is to map the use of e-cigarettes, but this is difficult due to absence of data sources for many countries.

The global number of vapers was estimated to be 68 million in 2020. New data in 2021 offered an opportunity to update that estimate. The method of assumed similarity was used for countries with missing data. The average prevalence of vaping was calculated for each World Health Organization region, World Bank income classification group and the legal status of e-cigarettes in each country. The number of vapers was calculated for the adult population. The estimate was refined by adjusting for changes in market value size and the actual year of surveys.

Population prevalence data on e-cigarette used were available for 48 countries. We estimate that there were 82 million vapers worldwide in 2021: 9.2 million in the Eastern Mediterranean region; 5.6 million in the African region; 20.1 million in the European region; 16.8 million in the Americas; 16.0 million in the Western Pacific region; and 14.3 million in South-East Asia.

Global, regional and national estimates of the numbers of vapers are important indicators of trends in nicotine use, and monitoring the uptake of vaping is important to inform international and national policy.
