Tobacco Control Policy and Tobacco Product Use Disparity in Japan
Tobacco smoking continues to be a major contributor to mortality, morbidity, and social inequalities in health worldwide. Smoking prevalence and inequality are influenced by tobacco control measures and interference from the industry including Japan Tobacco. Tobacco control is weak in Japan by international standards. Control measures such as taxation, labelling, and smoke-free legislation have differing effects on smoking inequality. Quit rates differ across socioeconomic strata, as does exposure to second-hand smoke. Equity effectiveness research takes account of socioeconomic gradients in response to new control measures and products. In Japan, e-cigarettes with nicotine have been prohibited since 2010. New heated tobacco products were introduced in 2013 and their use increased dramatically from 2016. To monitor smoking behaviour and health inequalities in Japan, we need to focus on heated tobacco products as well as cigarettes.
