I have your answer.

and it is hookah.

sheesha specifically. you can't even feel it in your lungs and it tastes like fruit and comes in various flavor. only other thing that touches my lungs besides herb and air.

It doesn't even burn really. its just a hot coal on tin foil that "heats" it up then it goes through water and a fat tube. I took a 30 second drag and blew out the whitest thickest clouds I'd ever seen.

And youll get the headrush of a lifetime may I add.
