I only smoke out of my bong, it is the most efficient and economical way to smoke weed that I can think of.
I have been smoking weed for 34 years and in that time I have smoked more joints, bowls, one hitters, gravity bongs with soda bottles, bazookas, bellows smokers, carburators, bubblers, sneak A tokes and regular bong hits with my "retooperator" that I have come to find a bong hit gives the best bang for the buck.

"Retooperator" is like a resperator only better because you get stoned.
