Sleep complaints and cannabis use are common among University students and are
related to detrimental effects on health. The aim of this study was to explore
their association. This cross-sectional study based on the i-Share e-cohort
included French students between 18 and 30 years old (n = 14,787). Frequency of
cannabis use was categorized into daily, weekly, monthly, and never/rarely use.
Sleep complaints were defined using four items (i.e., insomnia, sleepiness, poor
sleep quality, and sleep deprivation). In the whole sample (mean age: 20.4
years, 75.5% of females), 22.7% had insomnia, 18.3% had sleepiness, 22.4% had
poor sleep quality, 52.5% had sleep deprivation, and 5.8% used cannabis weekly
or daily. After adjustment, the likelihood of insomnia was significantly higher
by 45% in cannabis users compared to non-users. The estimates steadily increased
with frequency of use, reaching a 2.0-fold higher likelihood of insomnia in
daily users compared to never/rarely users. Results were similar for the other
sleep complaints. These findings provide support for an association between
cannabis use and sleep complaints, particularly insomnia, among University
students. Though direction and causality cannot be established in this setting,
these results suggest warning students and health professionals about the
association between cannabis use and sleep complaints.
