†
An alternative model that also controlled for child deviant peer association was fit to the data; results indicated that child deviant peer association marginally predicted child marijuana use onset (OR = 1.74, p = .054) but did not attenuate the effect of child peer marijuana use on child marijuana use onset (OR = 2.54, p = .001).
