All regressions are estimated using a fixed-effects model. C. indica and C. sativa are relative to hybrid, THC categories are relative to THC between 0 and 9%, CBD categories are relative to 0% CBD, and pipe and vape are relative to joint. Standard errors, clustered at the individual user level, are shown in parentheses.
