The role of public policies in reducing smoking prevalence and deaths caused by smoking in Arizona: results from the Arizona tobacco policy simulation model.

Arizona was one of the first few states to implement a comprehensive tobacco control program. The effect of that program is examined using a computer-simulation model (SimSmoke) developed for the purposes of evaluation, planning, and justifying policies. This approach assesses the impact to date of tobacco control policies on smoking prevalence and generates predictions about the effects of tobacco control policies on past and future smoking prevalence and associated future premature mortality. SimSmoke estimates indicate that tobacco control policies reduced smoking rates in Arizona by about 20 percent over the period 1993-2002. A previous CDC study obtains similar effects, but does not net out the effects of individual policies. SimSmoke attributes much of the reduction, about 61 percent, to price increases and attributes 38 percent of the overall effect to media policies, leaving only a small percentage of the smoking reductions attributed to quitlines, youth access policies, and the weak clean air laws. Tobacco control policies implemented as comprehensive strategies have significantly affected smoking rates in Arizona, which leads to large reductions in deaths attributable to smoking. It will be important to maintain these efforts over time to reduce or keep smoking prevalence down and to minimize smoking-attributable deaths.
