ok at the risk of grossin some folks out and perpetuating my silly arse gags, here goes...
greek inhale-advanced technique
clean your colon out well with an enema
place the bong up to your arse.
do not use a joint as the filtered smoke is cooler and besides, its hard to smoke down to the end without getting the redye in yr browneye.
light the bong and do a reverse fart, inhaling into the anal cavity.this can be tricky so u may wanna do a "dry run" first to get the hang of it.
hold the smoke there and let it absorb into the thin lining of thhe arsewall.
the thc is readily absorded much like suppository pharmaceuticals.
hold the hit for as long as you can, clenching tight
then to the amazement of your firends and family, blow a massive cloud of sweet herbal fart gas.
