it's for a hookah i can tell you that much... and the fact that it says stay far from the "incense" i'm going to say means be fuckin careful cuz it's powerful... salvia doesn't even come with a warning like that (i got mine from the same site) and anyone that's done salvia knows the power it holds...so if salvia didn't come with a warning like that... i'm going to guess that... i wouldn't touch that stuff with a 10 foot pole.. salvia was almost too much for me to handle.
