I think the way it's going pipes/cigars/snuff/snus or chaw are all going to grow. The medical profession is at the seminal point of accepting the health benefits of nicotine and seeing the facts that what makes tobacco bad is putting it in cigarettes and inhaling it. Once they more widely accept those facts then the public opinion will start turning. Especially when they notice how many old farts are still puffing away and somewhat vital. Seriously that's how I see it. And it's a pretty easy prediction to make. Medical dogma seems to have a life cycle of being over turned. It's weirdly almost always the same starts small with people basically being called cranks. Starts seeping up the chain until there are things like proposals internally at places the W.H.O. and other places and then boom everything turns. (trust me it's a very noticeable pattern and it's already at the point where the big organizations are reconsidering their stance). Seriously they're a stubborn bunch but they do change their minds when evidence starts smacking them in the face.
