No but I have seen it. I think they had some kind of apple in the mix as it smelt like apples, not bad at all like tobacco.
I have this idea that it is like the "vaping" that everybody does now . . . all different flavours but no tobacco any more. However, those e-cigarette vape things have exploded in several peoples' faces. *Nasty* Perhaps the old ways are best. . . . but not for me. :-))
Yes, there are different 'flavours' of tobacco you can buy for hookah use.
