Ontario, Canada: Cannabis consumers in the United States and Canada prefer flower over extracts, edibles, or other alternative forms of the plant, according to survey data published in the International Journal of Drug Policy.
Investigators affiliated with the University of Waterloo in Ontario surveyed over 27,000 subjects in the U.S. and Canada regarding their marijuana consumption habits. Consistent with prior studies, authors reported, "Dried herb was the dominant form of cannabis reported by past 12-month users across all jurisdictions."
Respondents in legal states reported consuming cannabis flowers more frequently than those in non-legal jurisdictions. However, researchers reported that "the [total] amount of dried herb used over the past year was similar across jurisdictions."
The use of high-potency concentrate products was more prevalent in legal markets than in states without such markets. Respondents in all jurisdictions were least likely to report having consumed edible cannabis products.
