One of our patients lit up in the bathroom at work. Probably only smoked a couple of minutes. Stunk up the entire hallway. That bathroom reeked for hours. It is amazing how strong that scent can be now that most places are free of it. It is hard to imagine working in a smoky environment, but my first jobs were like that. I guess it's all what you're used to.
I feel sorry for that patient who couldn't go without for even an hour or so. No such thing as sneaking a smoke anymore. It is obvious as hell, even if we hadn't seen the cloud of smoke appear when the door opened.
