Probably of cannabis use context by latent class at Wave 4. Proportions greater than .50 are bolded. Class 1 (alone and with friends) contained 127 individuals (46.2%); class 2 (with friends) contained 63 individuals (22.9%); class 3 (all contexts) contained 57 individuals (20.7%); and class 4 (at home) contained 28 individuals (10.2%). The first LCA was conducted with Wave 4 rather than Wave 3 because two of the three cannabis use variables of interest (motives and protective behavioral strategies) were not assessed at Wave 3. The LCA conducted on Wave 3 produced the same classes.
