“…Among most cross-sectional and longitudinal papers, 6 , 23 , 24 , 28 , 35 , 36 , 38 , 55 , 56 , 60 , 65 , 67 , 68 evidence consistently suggested a positive association between SAM use or same-day co-use and number of negative consequences experienced, even after controlling for demographics, impulsivity, delinquency, motives, alcohol use, and/or marijuana use. Of these papers, half focused on comparing individuals who engage in SAM use to individuals who use both substances concurrently or individuals who use alcohol only, 6 , 24 , 35 , 36 , 38 , 68 whereas the remaining focused on SAM use frequency as a predictor of consequences. 23 , 28 , 55 , 56 , 60 , 67 In both college and community samples, individuals who engaged in SAM use reported a greater number of negative consequences relative to those who used alcohol only, 24 , 35 , 36 though findings were mixed when comparing individuals who engaged in SAM use with those who used concurrently.…”
