well thats how i smoke, i dont use the shower though. what i do to make it now smell is i take the cardboard out of a toilet paper roll and stuff 2 sheets of fabric softener in there, then i wrap 1 piece around 1 of the sides and tie it off with a rubber band. then all i do is turn on that vent, take a hit, and blow the smoke through that cardboard roll into that vent, it works.
