Those who reported that most-all of their best friends used cannabis had significantly higher PRS than those who reported that “none” of their best friends used cannabis (most significant OR = 1.38, 95% C.I. = [1.07, 1.78], p = 0.012). Other comparisons (e.g., none vs. few: p = 0.799; few vs. most-all, p = 0.096) did not significantly differ from each other on cannabis PRS (details in Supplemental Material).
