Purpose:
This study aimed to investigate potential bidirectional relations between key sleep characteristics and somatic symptoms with past 30-day marijuana use in high school students.
Methods:
Participants from the NEXT Generation Health Study (n = 2,770) reported on 10th and 11th grade (W1 and W2) sleep characteristics and somatic symptoms and 12th grade (W3) past 30-day marijuana. Multivariate logistic regressions and path analyses were conducted.
Results:
Sleep duration was not associated with marijuana use. However, later W1 chronotype, greater W1 social jetlag, W1 trouble falling asleep, W1 trouble staying asleep, and W1 somatic symptoms were associated with increased odds of W3 past 30-day marijuana use. Path models indicated direct associations between W1 chronotype and W3 past 30-day marijuana use, and W1 social jetlag and W3 past 30-day marijuana use.
Conclusions:
Later sleep timing was longitudinally associated with past 30-day marijuana use. Improved understanding of sleep health, specifically chronotype and social jetlag as risk factors for marijuana use is warranted, which may inform additional screening targets and interventions that address these associated domains.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
