California’s governor on Monday ordered a public awareness campaign on health risks posed by a “youth epidemic” of vaping, but said he lacked authority to unilaterally ban flavored e-cigarettes that he said were deliberately marketed to children. Governor Gavin Newsom, acting a day after New York Governor Andrew Cuomo announced such a ban, became the latest politician seeking to crack down on e-cigarettes and other electronic inhaling – or vaping – devices, which have exposed a new generation of young people to nicotine hazards. Public health officials have said fruit- and candy-flavored e-cigarettes are luring millions of teenagers into using vaping products and becoming addicted to the nicotine they contain.
