Let's see. It looks like about a million people a year die of lung cancer, with about 90% of those attributed to smoking. But we still haven't seen any statistics on the number of burn victims and damaged/destroyed gas stations due to popping into the 7-11 for a Slurpee while the tank fills.
Lung cancer is extremely rare, regardless of your risk factors. Yet people are still told not to smoke because of the risk increase over it.
