Simultaneous use of alcohol and cannabis or marijuana ("SAM") use is prevalent among young adults and associated with adverse outcomes. Impulsivity is a key construct associated with alcohol and other substance use in this age group, but scant work has considered the role of individual facets of impulsivity on SAM use. The present study compared latent profiles defined by facets of impulsivity (negative urgency, lack of perseverance, lack of premeditation, sensation seeking, and positive urgency) and examined whether profiles were associated with recent SAM use relative to alcohol without cannabis use. Participants were 542 young adults (53% female) recruited through Qualtrics Panels who reported past-year alcohol use and blackout drinking behavior. Participants completed online questionnaires regarding their past-year substance use behavior and typical impulsivity. Regression analysis examining the five impulsivity facets revealed that only sensation seeking predicted the likelihood of recent SAM use relative to alcohol without cannabis use. Using latent profile analysis, four profiles were identified: "low impulsivity," "high sensation seeking/urgency impulsivity," "moderate impulsivity," and "high lack of premeditation/perseverance impulsivity." Individuals in the high sensation seeking/urgency group were more likely to engage in SAM use. Impulsivity may be an important individual difference factor associated with SAM use. Young adults who engage in SAM use may be particularly vulnerable for impulsivity related to sensation seeking and urgency, which may further heighten their risk for hazardous use and related outcomes.

同时使用酒精和大麻或大麻（“SAM”）在年轻人中很普遍，并且与不良后果有关。冲动是与该年龄段酒精和其他物质使用相关的关键结构，但很少有研究考虑冲动的个体方面对 SAM 使用的作用。本研究比较了由冲动的各个方面（消极紧迫感、缺乏毅力、缺乏预谋、寻求刺激和积极紧迫感）定义的潜在特征，并研究了这些特征与最近的 SAM 使用相对于没有大麻的酒精使用是否相关。参与者是通过 Qualtrics 小组招募的 542 名年轻人（53%为女性），他们报告了过去一年的酒精使用和断片饮酒行为。参与者在线完成了关于过去一年物质使用行为和典型冲动性的问卷。检查五个冲动性特征的回归分析表明，只有寻求刺激预测了最近 SAM 使用相对于没有大麻的酒精使用的可能性。使用潜在剖面分析，确定了四个特征：“低冲动性”、“高寻求刺激/紧迫感冲动性”、“中度冲动性”和“高缺乏预谋/毅力冲动性”。寻求刺激/紧迫感较高的个体更有可能从事 SAM 使用。冲动性可能是与 SAM 使用相关的重要个体差异因素。从事 SAM 使用的年轻人可能特别容易受到与寻求刺激和紧迫感有关的冲动的影响，这可能会进一步增加他们对危险使用和相关后果的风险。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
