From: Puff, Puff, Don’t Pass: harm reduction for cannabis use during a viral respiratory pandemic
Sharing cannabis before and during the COVID-19 pandemic across levels of cannabis use. Data presented as the percent frequency distributions for sharing of prepared non-medical cannabis and cannabis-related paraphernalia before and during the pandemic across levels of non-medical cannabis frequency of use before the pandemic. Frequency of non-medical cannabis use was dichotomized as once or twice/monthly (≤ monthly) use and weekly/daily (≥ weekly) use. Changes in sharing were evaluated using McNemar’s test for paired data by examining discordance between reported sharing before and during the pandemic for each level of sharing (i.e., discordance in no sharing before and during). P values < 0.05 are indicated with an asterisk (*). A p value using McNemar’s test for paired data for some categories was not computed when the sample size for at least one discordant pair was less than 5 is indicated by a double asterisk (**). Sample size of sharing cannabis among those reporting ≤ monthly use was 419 and 506 for those reporting ≥ weekly/daily
