Electronic cigarettes makers under fire in Senate

WASHINGTON -- Lawmakers are questioning e-cigarette makers about whether they're trying to hook youngsters with fruity, fun-sounding flavors such as "cherry crush."

Senate Commerce Committee Chairman Jay Rockefeller tells e-cigarette makers that the last thing anyone should want to do is encourage young people to start using a new nicotine delivery product.

The presidents of two companies, blu eCigs and NJoy, insist that they don't target young people and that their products are a critical alternative for people desperate to quit traditional cigarettes.

Electronic cigarettes heat a liquid nicotine solution, creating vapor that users inhale. But there isn't much research about the safety of e-cigarettes, and the studies that have been done have been inconclusive.
