(Reuters) – U.S. teens who try electronic cigarettes may be more than twice as likely to move on to smoking conventional cigarettes as those who have never tried the devices, researchers from the University of Southern California said on Tuesday.

“Adolescent brains appear to be especially susceptible to becoming addicted to nicotine when exposed,” Rigotti told Reuters Health in an email.
