Amazing how many of us nurses are smokers. Now quite a few of us where I work have switched to vaping. Considering how Godawful cold it's been here it's actually better to go out for a few quick puffs and go back in without the hassle of lighting up, sucking down a quick half a smoke, butting it and poking the other half back in the pack to save for the next quick break. Only advice...don't use a metal drip tip when it's 40 below or worse!
