Well with joints and blunts, obviously, they are pretty much burning all the time until it's gone. That means that between hits, it's still burning. When I take hits with a bong or especially a pipe, if I try I can make sure so that 100% of the time the stuff is burning, the smoke is going in to my lungs.

I might consider a blunt if I had lots of schwag or something. It gets annoying having to take like 100 bong rips of schwag just to get high.
