WASHINGTON (AP) — E-cigarettes with fruity flavors like “cherry crush” ignited an intense Senate debate Wednesday about whether manufacturers are trying to appeal to youngsters similar to the way that Big Tobacco used Joe Camel decades ago.

“The last thing anyone should want to do is encourage young people to start using a new nicotine delivery product,” Senate Commerce Committee Chairman Jay Rockefeller, D-W.Va., said as he opened a hearing on the battery-powered devices and worries that e-cigarette makers aim to tempt young people to take up something that could prove addictive.
