The U.S. Food and Drug Administration is probing the dangers of exploding batteries in e-cigarettes, following dozens of reports of devices that have combusted, overheated or caught fire and sometimes injured users.
Officials say an American Airlines flight from Dallas to Indianapolis was forced to make an emergency landing in Arkansas after a passenger's electronic cigarette "malfunctioned" and started a small fire.
The Liberal government says it will introduce legislation this fall to regulate vaping. Health Canada says the move will balance the need to protect young people from nicotine addiction while allowing adult smokers to legally buy vaping products.
U.S. health officials warn that electronic cigarettes and other vaping devices are poisoning kids with nicotine. But new research suggests that most teens aren't vaping nicotine at all but using sweet and fruity flavours like strawberry, chocolate cake and bubble gum.
Parents and doctors questioning teens about whether they smoke should also be asking if they're using e-cigarettes, which could be a gateway to nicotine addiction later on, says a pediatrician who led a new study.
