“…Among adult population in 2009–2014 ( n = 172–12,711), lifetime cannabis use or dependence was associated with lifetime and past‐month tobacco smoking (aPR: 2.18 and 4.06, both p < 0.01) [98], lifetime crack‐cocaine use (aOR: 19.1, p < 0.01) [99], and higher rates of initial use of several other psychoactive drugs (e.g., cocaine, ecstasy, psychedelics) (adjusted hazard ratio 1.9–12.1, all p < 0.05) [100, 101]. Among undergraduate students assessed between 2010 and 2016 ( n = 221–1423), associations between cannabis use and at‐risk drinking (aOR: 2.69–3.89, p < 0.01) [79], tobacco use ( B = 0.75, SE = 0.12, p < 0.001) [72], alcohol and tobacco use ( p < 0.01) [66], and LSD and/or ecstasy use (PR: 8.5, p < 0.001) [102] were identified. Regarding public school students in 2014 (11–19 years; n = 1059 and 6387), cannabis use was associated with lifetime and past‐month tobacco smoking (aPR: 1.64 and 2.31, both p < 0.001) [103] and past‐year binge drinking (aOR: 2.2, p = 0.01) [104].…”
