Note. For any SAM use, logistic regression was used to obtain the estimates, SE, Wald χ2, and ORs reported here. Supplementary regression models using the Poisson distribution were conducted using procedures described by Zou (2004) to obtain relative risk, and the estimates, SE, and Wald χ2 from those supplementary models are not shown. N = 167 for any SAM use, N = 157 for days used marijuana, N = 156 for marijuana consequences.
