同时和同时大麻和酒精共同使用赋予风险的日常负面酒精后果。然而，研究通常将共同使用视为二分法，排除了对高风险和低风险共同使用日的检查。此外，人们对与日常共同使用相关的特定酒精后果知之甚少。因此，目前的研究1）根据酒精消费，共同使用和同时使用区分天数，2）测试某些日常使用模式是否会导致日常酒精后果的风险。大学生共同使用者（N=489）完成了在线时间轴随访，报告了过去一个月的每日饮酒量、负面饮酒后果、同时使用大麻和酒精以及饮酒日同时使用（SAM）。日水平潜在特征分析根据饮酒量、共同使用和同时使用区分天数，并测试使用模式是否会导致整体和特定负面酒精后果的风险。出现了四个日水平曲线，包括中等消费量的仅酒精日（57.5%），中等消费量的SAM使用日（29.1%），较高消费量的仅酒精日（7.4%）和较高消费量的SAM使用日（6%）。较高的消费SAM使用天与更多的负面酒精后果比所有其他天，但是，较高的消费SAM使用天不同于较高的消费酒精只天的急性依赖症状。与适度消费SAM日相比，高消费仅酒精日与更多的负面酒精后果相关，特别是那些以行动为导向的日子（即，依赖症状、无意识饮酒、控制力受损、危险行为、社会/人际后果）。研究结果表明，实际上存在风险较低的共同使用日，并且与独特的负面酒精后果的联系取决于酒精消费和共同使用的水平。
Concurrent and simultaneous cannabis and alcohol co-use confers risk for daily negative alcohol consequences. However, studies often treat co-use as a dichotomy, precluding examination of higher- and lower-risk co-use days. Additionally, little is known about specific alcohol consequences associated with daily co-use. Therefore, the current study 1) differentiated days based upon alcohol consumption, co-use, and simultaneous use, and 2) tested whether certain day-level use patterns conferred risk for daily alcohol consequences. College student co-users (N=489) completed an online Timeline Followback, reporting daily alcohol consumption, negative alcohol consequences, concurrent cannabis and alcohol co-use, and simultaneous co-use (SAM) on drinking days over the past month. Day-Level Latent Profile Analysis differentiated days based upon drinking quantity, co-use, and simultaneous use, and tested whether patterns of use conferred risk for overall and specific negative alcohol consequences. Four day-level profiles emerged, including moderate consumption of alcohol-only days (57.5%), moderate consumption SAM use days (29.1%), higher consumption alcohol-only days (7.4%), and higher consumption SAM use days (6%). Higher consumption SAM use days were associated with more negative alcohol consequences than all other days; however, higher consumption SAM use days differed from higher consumption alcohol-only days in acute dependence symptoms. Higher consumption alcohol-only days were associated with more negative alcohol consequences than moderate consumption SAM days, particularly those that were action-oriented (i.e., dependence symptoms, blackout drinking, impaired control, risky behavior, social/interpersonal consequences). Findings suggest that there are in fact lower-risk co-use days, and that links with unique negative alcohol consequences depend on levels of alcohol consumption and co-use.
