My pipe has lots of resin in it caked on the walls really thick under the bowl and all thru the pipe, i just take my lighter put my flame in the bowl and breathe it in thru the hole, burning the resin inside ur pipe, we call this resin hits =)

u just kind of smoke the bowl without anything there. it gets me really baked after just a few hits, the high is more of a heavy / groggy kind of high and resin tastes like ass =P
