i am a non smoker but recently smell smoke most of the time. i live in a non smoking enviroment but this problem happens in and out of the house.anyone ever had this problem?
It's probably something quite minor but, as IAP suggests, it could be a sign of something more serious. (In particular, a persistent imaginary smell can be a symptom of a brain tumour).
Don't panic - it probably really is something very minor - but do get it checked out a.s.a.p.
