Actually, this is how I smoke before I go to bed. My wife doesn't smoke and doesn't neccasirly like that I do. So before bed, I shower and run it on hot until the bathroom is all steamy, then I smoke. It doesn't make me feel any higher, but it does get rid of the smell. I usually only have to run the exhaust fan for like 5 minutes. Although there have been times my wife walked in immediately after and couldn't smell a thing.
