大麻（MJ）是美国最常用的娱乐性药物。关于MJ和睡眠之间关系的研究仍处于起步阶段。该研究考察了日常使用者，非日常MJ使用者和非使用者的社区样本之间的睡眠特征差异。共有98例受试者（45例男性; 53例女性）参与。平均年龄为22.3岁（SD=3.0）。有53名女性，55%的样本是白人。招募是通过网上和社区印刷广告进行的。将组分为非每日使用者（n=29）、每日使用者（n=49）和非使用者对照组（n=20）。采用匹兹堡睡眠质量指数（PSQI）、失眠严重程度指数（ISI）、埃普沃思嗜睡量表（ESS）和晨起量表（MEQ）评定睡眠状况。ISI的标准截止分数>10在38.8%的日常使用者、10.3%的非日常使用者和20%的非使用者中被发现。日常使用者的PSQI评分（7.0 +/-3.8）高于非日常使用者（4.9+/-3.2）和非使用者对照组（5.0+/-3.7），p=0.02。每日使用者的ISI评分（7.9 +/-6.1）高于非每日使用者（5.1 +/-4.3）和非使用者对照组（4.3+/-4.8），p=0.01。协变量调整回归分析显示，平均PSQI和ISI评分显着较低的非日常用户和控制相对于日常用户。当调整抑郁和焦虑时，这些独特的关联并不显着。ESS和MEQ无差异。每日使用MJ的人比非每日使用MJ的人更容易出现睡眠障碍。未来的研究应该考虑MJ使用和睡眠之间关系的情绪。
Marijuana (MJ) is the most commonly used recreational drug in the US. Research on the relationship between MJ and sleep is still in its infancy. The study examined the differences in sleep characteristics between a community sample of daily users, non-daily MJ users, and non-users. A total of 98 subjects (45M; 53 F) participated. The mean age was 22.3 (SD=3.0). There were 53 females and 55% of the sample was Caucasian. Recruitment was through online and via print advertisements in the community. Groups were categorized as non-daily users (n=29), daily users (n=49), and non-user controls (n=20). Sleep was characterized by the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS) and Morningness Scale (MEQ). A standard cut off score of >10 for the ISI was found in 38.8% of daily users, 10.3% of non-daily users, and 20% of non-users. PSQI scores in daily users (7.0 +/− 3.8) was higher than non-daily (4.9+/−3.2) and non-user controls (5.0+/− 3.7), p=0.02. ISI scores in daily users (7.9 +/−6.1) were higher than non-daily (5.1 +/−4.3) and non-user controls (4.3+/−4.8), p=0.01. Covariate adjusted regression analyses revealed mean PSQI and ISI scores were significantly lower for non-daily users and controls relative to the daily users. When adjusting for depression and anxiety, these unique associations were not significant. There were no differences in ESS or MEQ. Daily MJ users endorsed more sleep disturbance than non-daily users. Future studies should consider mood in the relationship between MJ use and sleep.
