Bubblers!!!

Bongs don't waste weed, not my bong anyway. I'll load up a bowl for the bong and be high as hell half way through and forget I still got half to go. Also, when u light the bong don't light the weed in the center. Start on a corner of the bowl and work your way around. You'll get the most out your green that way.

I don't find bubblers or bongs a waste either. I'll take 2 big bubbler rips and get just as fried with 5 pipe hits. You get monster hits and with the right kind of weed, it expands in your lungs, and sends your head a flying!
