Don't worry about any of this grego, for you it just a natural occurrence. It maybe that you are less inhibited than most so you see more. The fag smoke may be that of a spirit of a visiting relative, or maybe someone who has an interest in an occupant of the household or it could be from a previous occupation. I know you said that is a new build property, but you need to take in to account that occupation may have been going on around that site for hundreds of years, you should also keep in mind that, just because its you that sees them doesn’t mean that it you their interested in? I live in a new build and I get the same smell and it’s recurring more often. But it as only come about within the last 2 years.
