Price points with an asterisk (*) and bolded data indicate there was a significant effect at p < .05 and a hash (#) indicates there was a significant effect at Bonferroni corrected p < .005 of cannabis availability on opioid consumption when transformed data were analyzed, Cohen’s d characterizes the effect size of the matched-pairs t-test at each individual price point.
