Putting the cherry of a cigarette onto a flat piece of hash and inhaling the smoke that comes off of the cherry, you can also hold a pen tube in your mouth and inhale to make it less harsh. Some people also use a bottle as a funnel and put the cigarette underneath to let the smoke rise into it, it then becomes "Bottle Tokes". Most commonly used in Eastern Canada. (Maratimes) Also known as BT's for butt tokes or bottle tokes.
