While the global smoking rate has dropped in the past 30 years (from 41.2% of men in 1980 to 31.1% in 2012 and from 10.6% of women in 1980 to 6.2% in 2012), the number of tobacco smokers has increased due to population growth (Ng et al., 2014). This tobacco use and second-hand smoke exposure continue to harm people worldwide. Those harmed are often vulnerable: children, those living in low- and middle-income countries (LMICs), those with existing diseases, etc. As noted by the World Health Organization (WHO), nearly 80% of those who smoke live in a LMIC (World Health Organization, 2017). Furthermore, it is often those who are more socio-economically disadvantaged or less educated in LMICs that are exposed to second-hand smoke at home and work (Nazar, Lee, Arora, & Millett, 2015).
