I wasn't very successful with snuff. My sinus problems might have been caused by it, and I only snuffed for a couple of weeks or so. Then again, maybe the problems were lying under and the snuff helped bring them up. Who knows. I still have most of the bag I got early in AD 2015, and my two plastic 'tins' of Bernard Schmalzer. I occasionally take some, but it's not regularly.
I'd also want to keep my pipe to 1-2 bowls a day. In that way, maybe living in a non-smoking building might be more of a boon than a hassle; yet, with the winter coming, smoking outside is gonna be more difficult.
