It looks like the war against electronic cigarettes will have several fronts.

One day after state Attorney General Jerry Brownfiled suit against one maker of the “e-cigarettes,” Senator Ellen Corbett, D-San Leandro, announced the introduction of a bill that would prohibit their sale to minors. Last year, Gov. Arnold Schwarzenegger vetoed a bill, also by Corbett, that would have banned the sale of e-cigarettes in the state entirely.

What are electronic cigarettes, you ask? Well, they look just like regular cigarettes — down to the light at the end of the product that glows when a person inhales — but are battery-operated and contain cartridges filled with nicotine. When a user inhales, a heating device converts the chemicals contained in the cartridge into a vapor that can also be exhaled and resembles smoke.
