Individuals with chronic lower back pain (CLBP) report using alcohol and marijuana to cope with pain. Little research has tested whether co-use is associated with worse psychological outcomes.
Participants had CLBP and past-month alcohol/marijuana co-use (n = 192), alcohol use (n = 148), marijuana use (n = 78), or no use (n = 101).
Co-use was associated with more drinking-related problems, anxiety, and pain anxiety compared to alcohol-(but not marijuana-) only, whereas marijuana-only use was associated with worse psychological outcomes than alcohol use-only; effect sizes were small to medium.
Co-use and marijuana-only were associated with worse outcomes than alcohol-only.
The present findings extend current understanding of co-use by finding that marijuana use among people with CLBP (a group with especially high rates of use of these substances) is associated with worse alcohol-related problems and psychological outcomes.
慢性下腰痛（CLBP）患者报告使用酒精和大麻来缓解疼痛。很少有研究测试过共同使用是否与更糟糕的心理结果有关。
参与者有 CLBP 和过去一个月的酒精/大麻共同使用（n=192）、酒精使用（n=148）、大麻使用（n=78）或无使用（n=101）。
与仅酒精使用相比，共同使用与更多与饮酒相关的问题、焦虑和疼痛焦虑有关，而与仅大麻使用相比，酒精使用仅与更差的心理结果有关；效应大小为小到中等。
共同使用和仅大麻使用与酒精使用相比，与更差的结果相关。
本研究发现，与仅酒精使用相比，大麻使用与 CLBP 患者（使用这些物质的比率特别高的群体）的酒精相关问题和心理结果更差有关，这扩展了对共同使用的现有理解。
