Note. Figure vertical bars represent mean values on the past year frequency measure for each substance and by the indicated groups. Values in boxes indicate chi-square values between indicated groups (e.g., chi-square difference between class 1 and class 2 for marijuana frequency is 0.20). Shaded values are significant at p < .05.
