Frustrated by the slow pace of federal action, state attorneys general are waging their own campaigns against the sale and advertising of e-cigarettes to minors.

More than a dozen AGs, including those in New York, California, Indiana and Ohio, are using new state and local laws — some of which they helped craft — to put pressure on the industry at all levels, from neighborhood vape shops to big tobacco companies like Altria GroupĀ and Reynolds American Inc.

State actions have accelerated in the wake of government data released in April, which showed that teen use of e-cigarettes tripled in 2014 alone, making them more common for youngsters than tobacco.
