Simultaneous alcohol and marijuana (SAM) use - or use of both substances with overlapping effects - is common among emerging adults and is linked to increased risk for problematic substance use outcomes. The current study identified subgroups of emerging adult SAM users based on their typical alcohol and marijuana use patterns and compared groups on key individual characteristics. Latent profile analysis uncovered four profiles of SAM users (n=522): Light Users (LU; 49.0%), Moderate Drinkers with Frequent Marijuana Use (MDFM; 37.9%), Moderate Drinkers with High Peak Levels (MDHP; 5.4%), and Heavy/Frequent Users (HFU; 7.7%). Group differences by demographic characteristics were found, with LU more likely to be college attendees/graduates than MDFM. Additionally, HFU were more likely to be Greek-affiliated than both LU and MDFM. Groups also differed based on other drug use behavior and preferred route of marijuana administration. Findings demonstrate diversity among SAM users based on typical substance use patterns.
同时使用酒精和大麻（SAM）——即使用两种具有重叠效应的物质——在新兴成年人中很常见，并且与物质使用问题后果的风险增加有关。当前的研究根据新兴成年SAM使用者的典型酒精和大麻使用模式确定了亚组，并比较了各亚组在关键个人特征方面的差异。潜在类别分析揭示了SAM使用者的四种类型（n = 522）：轻度使用者（LU；49.0%）、经常使用大麻的中度饮酒者（MDFM；37.9%）、高峰水平的中度饮酒者（MDHP；5.4%）以及重度/频繁使用者（HFU；7.7%）。研究发现了各亚组在人口统计学特征上的差异，与MDFM相比，LU更有可能是大学在校生/毕业生。此外，与LU和MDFM相比，HFU更有可能与希腊社团有关联。各亚组在其他药物使用行为和大麻偏好给药途径方面也存在差异。研究结果表明，基于典型物质使用模式，SAM使用者存在多样性。
