nag champa is the best its hard to describe the smell but its awesome, the stuff with the cannabis plants on it dosent smell like pot its just marketed like that so people will make a connection to it and buy it.

some other stuff i found to smell good is patchoulli and the grateful dead brand incense one time i was high as a kite and watching the grateful dead movie and smelling the incense and i could have sworn thats what jerry garcia and the band must have smelt like.
