Because You are to pussy to breathe in?

Jus kidding :P

It's just an alternative method to smoking, I personally found gravity (bucket) bongs impractical and a waste of time, "lung" bongs however I think are pretty cool, and my non-smoking friends loved being able to get high by jus makin the smoke bypass the mouth, just straight into the lungs.

Eventually they started liking normal smoking tho

jonny Reviewed by jonny on . Gravity Bongs: Reusable Smoke? I just tried a gravity bong and it's now definitely my favourite smoking device. The equivalent of half a joint is all I needed. In any event, after taking a hit I wondered: "If I exhaled back into the bottle could I keep doing that and reuse the hit? I figured this was too good an idea to work, so what's the problem with it? I guessed either Carbon Dioxide buildup or loss of smoke potency after the first hit. Rating: 5
