The association between our exposure variable (state-level medical marijuana law) and marijuana outcomes was examined two ways: 1) a state-level regression and 2) a multilevel regression model of individual-level data nested within states. Using the NESARC, we performed both types of analyses for these three outcomes: past year marijuana use, marijuana abuse/dependence, and marijuana abuse/dependence among current marijuana users. Using the NSDUH, we performed a state-level analysis of past year marijuana use.
