Canoeing is a term used to describe the uneven burning of a joint. The blunt burns more on one side than the other, and trust me, and this takes the fun out of smoking. Imagine coming home after a long day, taking the time to roll a blunt, only for the joint to canoe after a few drags. It sometimes gets infuriating. To derive the most satisfaction from your joint, you must try everything possible to avoid canoeing.
