大麻经常与酒精结合使用;然而,大麻的使用是否会影响酒精使用障碍(AUD)的风险因素仍然未知。对酒精的主观反应(SR)是随后大量饮酒和发展AUD的生物行为风险因素。鉴于酒精和大麻共同使用的高流行率,假设大麻使用者与非大麻使用者相比,酒精的SR不同是合理的。本研究的目的是研究过去一个月的大麻使用对酒精的主观反应在人类实验室的影响。这项研究从多个酒精管理试验中挑选数据,以测试大麻使用者与非大麻使用者相比,对酒精的主观反应是否不同,包括四个领域:刺激,镇静,负面影响和渴望。非寻求治疗的重度饮酒者(N=168)完成了一系列情绪和酒精/香烟/大麻使用和问题的自我报告量表。所有参与者都完成了静脉内酒精给药阶段,其中在以下呼吸酒精浓度(BrAC)下测量SR域:基线(即,0)、20、40和60 mg %。多级统计分析显示,与非大麻使用者相比,大麻使用者在饮酒期间的负面影响减少得更多。其他SR域无显著差异。使用大样本和先进的数据分析方法,这项研究扩展了文献,表明与非大麻使用者相比,大麻使用者对酒精引起的负面影响减少更敏感。这项工作扩展了关于大麻使用如何影响AUD风险因素的研究,例如对酒精的主观反应。
Cannabis is often used in combination with alcohol; yet, whether cannabis use impacts risk factors for alcohol use disorder (AUD) remains unknown. Subjective response (SR) to alcohol represents a biobehavioral risk factor for subsequent heavy drinking and for developing AUD. Given the high prevalence of alcohol and cannabis co-use, it is plausible to hypothesize that cannabis users differ in SR to alcohol compared to non-cannabis users. The purpose of this study is to examine the influence of past-month cannabis use on subjective response to alcohol in the human laboratory. This study culled data from multiple alcohol administration trials to test whether cannabis users, compared to non-cannabis users, differed in subjective response to alcohol, comprised of four domains: stimulation, sedation, negative affect, and craving. Non-treatment-seeking heavy drinkers (N=168) completed a battery of self-report scales of mood and alcohol/cigarette/cannabis use and problems. All participants completed an intravenous alcohol administration session wherein SR domains were measured at the following breath alcohol concentrations (BrAC): baseline (i.e., 0), 20, 40, and 60mg%. Multilevel statistical analyses revealed that cannabis users had a greater reduction in negative affect during alcohol administration, compared to non-cannabis users. No significant differences were found for the other SR domains. Using a large sample and advanced data analytic methods, this study extends the literature by suggesting that cannabis users are more sensitive to alcohol-induced reductions in negative affect compared to non-cannabis users. This work extends research on how cannabis use may influence risk factors for AUD, such as subjective response to alcohol.
