e-cigarettes debate heats up

X-Halers Smokeless Cigarette and CD Stop Smoking Program
Consumers rave about them, but are electronic cigarettes safe?
(ABC News)- Electronic cigarettes are handheld nicotine-delivery devices that, despite a devoted following, are currently swirling in controversy.

New York is pushing to become the first state to ban the devices, which so far remain unregulated and mostly unstudied. With cutesy colors, fruity flavors, clever designs and other options, e-cigarettes may hold too much appeal for young people, critics warn, offering an easy gateway to nicotine addiction.

But those criticisms clash with equally strong arguments for the value of e-cigarettes. The devices, which are tobacco-free, may be a safer alternative to cigarettes, say advocates, who point to testimonials from thousands of smokers who say they have used e-cigarettes to help them quit.
