Just an herbal. Good if you wanna evade the clean air bullshit if you are in michigan, or whatever states are going it [they are banning smoking tobacco all over the place here, but tea and sugar cane is still a go!].
HookahHookah evolution is very good, most of the flavors are just as good as tobacco, slightly healthier.
Hydro is a sugar cane based herbal, great flavors, enormous clouds, however, slightly awkward aftertaste. You get used to it though.
