Okay, do bongs waste weed?

No...

Have you ever smoked a bong?

They get you HIGH

Therefore, whatever thc is 'lost' is SO miniscule it's absurd to imply that bongs are ineffective and wasteful. I don't give a fuck what NORML says, I know what I say, I know what my bong says. Joints waste more then anything. They need more weed to make a joint... The joint is constantly burning, thus you are losing thc. Sideburns... A bong takes less weed so it's not as wasteful as a joint. Perhaps a pipe is more efficient then all, HOWEVER, it's harsh as hell and not worth it, you wouldn't get that much higher from a pipe then a bong. If you smoke 0.3 in a pipe and 0.3 in a bong, it's the same.
