its gotta be bongs, if you do them right your not loosing any smoke at all .. with a pipe or joint or whatever, your loosing a little bit of smoke no matter how hard you try not to .. i also find bongs generally give you a better hit than anything else, your putting a big loads of smoke into your lung lungs in one qucik sup, can beat that buzz you get right after ripping a huge bong .. i live for it man.
