waste of weed imo.... you pack bud (or shoudl be atleast) ALOT tighter in bowls then in a blunt/joint.... therefore it burns alot faster.... also, creates alot, LOT more excessive burnage after you stop sucking if it's in a bong...

just a novelty idea... not to mention i'm yet to find one person that even sorta likes old blunt-smoke taste, so it stains your bong with a horrible taste...
