The 2014 Washington State Legislature directed WSIPP to identify programs and policies that can decrease tobacco and e-cigarette use and yield the greatest return on investment. WSIPP employed its standard approach to reviewing research evidence and conducting benefit-cost analysis.
We identified 40 topics with research of sufficient rigor to allow us to draw conclusions about effectiveness. Of the 40, we found that 33 produce, on average, reductions in tobacco use. We identified a few programs that have undesirable effects on outcomes.
Our findings apply to tobacco prevention and cessation strategies. For e-cigarettes, unfortunately, we were unable to locate any rigorous evaluations that measure the impact of prevention strategies. In this report we summarize state regulations as of October 2014 related to e-cigarettes.
