Sleep difficulties affect many young adults, leading over 20% to turn to cannabis or alcohol as sleep aids, according to new research published in JAMA Pediatrics. This finding sheds light on a prevalent but underrecognized health behavior with significant implications for public health and clinical care.
A study conducted by the Institute for Social Research at the University of Michigan evaluated 1,473 young adults aged 19 to 30 across the United States, surveyed during 2022–2023. The investigation focused on the frequency with which cannabis or alcohol was used intentionally to initiate sleep. The results revealed that 22.4% of these young adults reported using either substance to help fall asleep, with cannabis use for this purpose reported by 18.3%, and alcohol by 7.2%.
The motivation for the study arose from the growing recognition that many young adults struggle with sleep initiation or maintenance, conditions worsened by stressful life stages and modern lifestyle factors. Cannabis and alcohol are known to have sedative properties, but habitual use carries risks of tolerance, dependency, and disrupted sleep architecture.
Key Findings and Developments
The study highlighted that among those who used cannabis in the past year, 41.4% reported using it to help them sleep, compared to 8.6% citing alcohol for this reason. Daily or near-daily cannabis users had significantly higher odds—3.58 times—of using it as a sleep aid compared to nondaily users. Women were twice as likely to use cannabis for sleep compared to men within this group. Alcohol-to-sleep use showed a similar pattern with an adjusted odds ratio of 3.31 for daily users, and Black respondents had higher odds of alcohol use for sleep compared to White respondents.
The research underscores a potentially high prevalence of self-medication for sleep problems using psychoactive substances in young adulthood—a critical time when healthy sleep is essential for cognitive and emotional development.
Expert Perspectives
Dr. Megan E. Patrick, lead author of the study, emphasizes the need for clinicians to closely screen for substance use among young adults presenting with sleep difficulties. “Our findings suggest that sleep problems and substance use overlap significantly in this age group. Better screening and targeted intervention could mitigate health risks related to chronic substance use and potentially improve sleep outcomes,” she said.
Dr. Andrea Wycoff, a psychiatrist and substance use researcher not involved with the study, cautions that while cannabis may aid sleep initially, long-term use may lead to tolerance and disruptions in sleep quality. “Young adults using cannabis or alcohol as coping mechanisms for stress and sleep issues may unknowingly increase their risk of dependence,” she warned. Wycoff also points towards the need for more research into combined substance use and its consequences.
Background and Context
Sleep problems affect an estimated 30% or more of young adults. Factors contributing include academic or work stress, social pressures, and increased screen time. Cannabis and alcohol, due to their sedative effects, are sometimes viewed as accessible remedies. However, alcohol disrupts the normal sleep cycle and can worsen insomnia symptoms over time. Cannabis’s effects on sleep are more complex and may vary depending on dosage, frequency, and cannabinoid composition.
The study’s findings align with prior research indicating that habitual use of these substances for sleep may lead to tolerance—requiring progressively higher doses—and dependence, with withdrawal symptoms potentially exacerbating insomnia.
Public Health Implications
The widespread use of cannabis and alcohol as sleep aids among young adults suggests a need for public health initiatives promoting safe and effective sleep hygiene practices. Education about the risks associated with self-medicating sleep issues with psychoactive substances should be prioritized. Access to behavioral sleep therapies and mental health resources could provide healthier alternatives.
Clinicians should routinely inquire about substance use when addressing sleep complaints in young adults to tailor interventions appropriately. Public policies might also consider the implications of increased cannabis legalization on youth health behaviors and substance use patterns.
Limitations and Counterarguments
The study relied on self-reported data, which can be subject to recall bias. The cross-sectional design limits causal inference between substance use and sleep problems. There is variability in how cannabis products affect sleep, influenced by THC/CBD ratios, delivery methods, and individual sensitivity that the study did not dissect in detail.
Additionally, some young adults may experience genuine symptomatic relief from insomnia through cannabis, highlighting the complexity of clinical decision-making around these substances. More research, including randomized controlled trials, is necessary to clarify the long-term risks and benefits.
Practical Takeaways for Readers
-
Young adults experiencing sleep problems should seek professional advice rather than self-medicating with cannabis or alcohol.
-
Excessive or daily use of cannabis or alcohol for sleep increases the risk of dependence and worsened sleep quality.
-
Non-pharmacologic interventions such as cognitive behavioral therapy for insomnia (CBT-I), sleep hygiene education, and stress management may offer safer long-term benefits.
-
Awareness of the potential for tolerance and withdrawal effects is important for anyone using substances to aid sleep.
