That's completely ridiculous. I could see the children of chain smokers getting lung cancer from second hand smoke, but walking by someone smoking a cigarette, even every day, isn't going to give you lung cancer. Nicotine and batteries are placed into a small device that looks like a cigarette, you inhale through one end, and when doing so the device changes the liquid nicotine into a vapor, which is then inhaled. No smoke, no additives, no paper being inhaled, just nicotine.
