A new study by a national anti-smoking group argues that states could raise more than $9 billion in new revenues if they all hiked cigarette taxes by $1-a-pack. The levy wouldn’t come close to balancing recession-ruined state budgets, but it wouldn’t hurt. And, the group says, the higher tax would keep 2.3 million kids from becoming smokers and convince 1.2 million adults to quit, saving one million lives and $52 billion in health costs over the long-run. The study comes from the Campaign for Tobacco-Free Kids.
