Trends in the use and dual use of factory-made combustible cigarettes, other tobacco products and electronic cigarettes: Results from South African Social Attitudes Surveys during 2007 to 2018.

Introduction: Using more than one tobacco product increases the risk of tobacco-related diseases. We investigated trends in the prevalence and dual use of factory-made (FM) cigarettes, other tobacco products, and electronic cigarettes (e-cigarettes) in South Africa over a 12-year period.

Methods: Data from five waves (2007, 2010, 2011, 2017, and 2018) of the South African Social Attitudes Survey (n=14582) were analyzed.
