Haven't tried any of the non-tobacco stuff. Might be interesting to try now, I'm quite intrigued. Usually when someone mentions non-tobacco they refer to something that is illegal and I have no intention of using.
FWIW While I liked Al Fakher last time I was smoking my hookah regularly, I had to take it easy with the starbuzz. Lot of strong tobacco and it has a kick. I didn't like it as much.
