CHICAGO (AP) -- Chicago's City Council has approved a proposal that would limit the use of electronic cigarettes.
Aldermen voted Wednesday to expand the city's regulation of tobacco products to include e-cigarettes, barring their use in offices, indoor public areas and within a certain distance of building entrances.
Electronic cigarettes are metal or plastic battery-powered devices resembling traditional cigarettes that heat a liquid nicotine solution, creating vapor that users inhale. Users get nicotine without the chemicals, tar or odor of regular cigarettes.
But their popularity among young people has raised the concern of public health officials.
