State Cigarette Taxes (IMAGE) Washington University School of Medicine Caption Researchers at Washington University School of Medicine found that suicide rates declined in states that implemented higher taxes on cigarettes and stricter policies to limit smoking in public places. They also noted an increase in suicide rates in states that had lower cigarette taxes and more lax policies toward smoking in public. The map displays the range of state cigarette taxes from the lowest (lightest blue) to the highest (darkest blue).
