the longer you hold the smoke in, the less smoke u exhale... so do that, and blow every hit out the window. in the meantime, the water in the shower doesnt have to be burning hot... just enough to make the room a little foggy. spray frebreeze when ur done, just to make sure, then jump in the shower and brush ur teeth when u get out. i smoke in the bathroom all the time.. the only requirement is- u need a window.
