A cannon refers to a distinctive straight-walled cylindrical style of rolling paper and joint shape reminiscent of an old artillery cannon or pipe in proportions. Compared to standard gradually tapered cone-shaped joints, cannons are significantly fatter and more cola bottle-shaped, and typically designed to hold between 1 and 1.5 grams of flower when rolled. Pre-rolled cannon joints wrapped in colorful paper have become signature products of certain major West Coast and Canadian cannabis brands. The cannon’s characteristically straight-sided, untapered shape creates a more open air path when inhaling that some smokers clearly prefer over traditionally pinched ends. Combining a cannon joint with a hollowed-out center channel densely packed with hash oil or live resin creates a next level “hash hole” or “donut” joint. Aficionados also appreciate cannon proportions for providing a fuller flavor experience since the wider circumference does not restrict airflow over the packed flower material nearly as much as narrowly rolled spindly joints can. Their smoother hit more closely mimics the experience of inhaling from a pipe or bong.
