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.
