Strict tobacco control policies introduced in the last 20 years have made Brazil a public health success story by lowering smoking rates and deaths due to smoking, report researchers from the United States and Brazil (Levy D et al. PLoS Med. 2012;9:e1001336).
Using a computational simulation model called SimSmoke, investigators estimated the effect of tobacco control policies (such as a cigarette-specific tax introduced in 1990) on smoking prevalence and smoking attributable deaths. Between 1989 and 2010, there was a 46% decrease in smoking, and the model estimated almost half this reduction resulted from increasing the price of cigarettes.
