I think cigars and cigarettes will persist for a long time, and pipe smoking will be an arcane oddity.
I expect pipe tobacco is borderline profitable for the retailers, at least in Greece most carry it because they don't want to miss the very occasional customer. Certainly things look better in the US, and some countries in Europe like Germany, UK, Denmark.
Given that I believe abroad buying of tobacco will pretty much be eliminated for most of the world in the next couple of years I'm trying to cellar as well as to learn to grow and process my own. What I make will never be Samuel Gawith or Dunhil, but it'll be my own, free, and reliable.
