Policy surrounding cannabis legalization is gaining popularity. Legalization must be prescriptive to protect public health. Current Canadian legislative frameworks do not include clear regulations for cannabis package labeling. Regulating cannabis package colors, descriptors, and other brand imagery, as well as using health warnings, are crucial to control cannabis consumption levels. Based on an assessment of the harms linked to cannabis use, an evaluation of existing cannabis and tobacco legislations with respect to packaging labeling, and an extraction of examples from the tobacco labeling literature, this commentary highlights the need for further cannabis legislation in Canada and provides recommendations for cannabis labeling policy.
