New Jersey could become the second state to raise the smoking age to 21, as part of a movement that’s been spurred in part by a major study released last year and a sharp increase in electronic cigarette use among young people. The state’s Legislature on Monday passed a bill that would fine retailers up to $1,000 if they sell cigarettes or other tobacco products, including e-cigarettes that are often called “vapes,” to anyone 20 years old or younger.
