well now that we're on this one - wood is VERY stable-
I currently have in my possession a very OLD VERY VALUABLE PIECE OF WOOD - when I say very, it's estimated value is six figures -if this interest or intrigues you - PM me - it bores many so I don't get into it often
I rarely worry about it -I don't have a controlled environment like endowed museums
the last thing I'd worry about is a stinky pipe following a smoke
I leave it in a room I don't typically hangout in to air out - considering the cold garage
