Nearly one third of Americans experience poor sleep, which is associated with numerous deleterious health outcomes. Poor sleep may be exacerbated when an individual attends college, as they experience drastic shifts in lifestyle and sleep patterns. Previous research suggests cannabis has therapeutic potential for sleep disorders but may also impair sleep quality long-term. However, no study has examined the differences in sleep quality within individuals who meet criteria for Cannabis Use Disorder (CUD). The purpose of the current study was to determine differences in sleep quality among undergraduate students who met criteria for mild CUD (n = 18), moderate CUD (n = 22), severe CUD (n = 16) and students who did not meet criteria for CUD (n = 244). Participants included 300 predominantly Black/African American undergraduate students (79% female), aged between 18 and 25 years. Each participant completed an online survey that included measures assessing sleep quality and CUD criteria. Employing analysis of covariance, the moderate CUD subgroup (M = 9.00, SD = 3.32) reported poorer sleep quality than individuals who did not meet criteria for CUD (M = 6.93, SD = 3.03). Interestingly, the severe CUD subgroup (M = 6.75, SD = 2.52) reported similar sleep quality to individuals who did not meet criteria for CUD (M = 6.93, SD = 3.03). Individuals meeting criteria for mild and moderate CUD reported the poorest sleep quality among the groups, suggesting a differentiation within CUD severity. Future research should assess withdrawal and cannabis use frequency among individuals who meet criteria for CUD to further elucidate disturbances in sleep quality among those with CUD.

近三分之一的美国人睡眠质量不佳，这与许多有害的健康结果有关。当一个人上大学时，他们的生活方式和睡眠模式会发生巨大的变化，睡眠质量不佳可能会加剧。先前的研究表明大麻具有治疗睡眠障碍的潜力，但也可能长期损害睡眠质量。然而，尚无研究调查符合大麻使用障碍 (CUD) 标准的个体睡眠质量的差异。本研究的目的是确定符合轻度 CUD (n = 18)、中度 CUD (n = 22)、重度 CUD (n = 16) 标准的本科生和不符合标准的学生睡眠质量的差异对于 CUD (n = 244)。参与者包括 300 名主要是黑人/非裔美国本科生（79% 为女性），年龄在 18 至 25 岁之间。每个参与者都完成了一项在线调查，其中包括评估睡眠质量和 CUD 标准的措施。采用协方差分析，中度 CUD 亚组（M = 9.00，SD = 3.32）报告的睡眠质量比不符合 CUD 标准的个体（M = 6.93，SD = 3.03）差。有趣的是，严重 CUD 亚组（M = 6.75，SD = 2.52）报告的睡眠质量与不符合 CUD 标准的个体（M = 6.93，SD = 3.03）相似。符合轻度和中度 CUD 标准的个体报告各组中睡眠质量最差，这表明 CUD 严重程度存在差异。未来的研究应评估符合 CUD 标准的个体的戒断和大麻使用频率，以进一步阐明 CUD 患者睡眠质量的紊乱。
