I recently quit smoking all forms of tobacco (thank goodness!), my main poison of choice being the hookah. However, I'd still like to occasionally visit the old hookah lounge I went to, because I made so many good friends there. While I'm confident in my ability to avoid relapse (thanks in no small part to knowledge gleaned from this website), I'm a bit worried about all the second-hand smoke that is ubiquitous in a hookah lounge. Is it possible that sitting in a smoke-filled room for up to seven hours could deliver enough nicotine into my system to trigger another withdrawal, even if I don't smoke directly?
