As an ex smoker I have to say that traditional smokers freaking stink. Their clothes, bodies, breath, all smells like a wet ashtray. Smoke one cig and you smell all damn day. Brush your teeth, wash your hands and face. Does not work. Your hair and clothes still reek. I work in an office environment and can smell the smokers walk past my office. Serious.
I am an ex smoker...but not perfect at it. One here. A couple weeks, a month. Another there. Someday hopefully.
