NEW YORK - E-smokers in New York City will have to head for the exits. The city council has voted to expand the city's indoor smoking ban to include electronic cigarettes.
E-cigarettes heat a nicotine solution and emit a puff of vapor that manufacturers say is harmless.
Most scientists agree that e-cigarettes are less dangerous than tobacco. But the e-cigs are still highly addictive.
Some anti-smoking activists say it isn't clear whether they are truly safe.
