Sleep hygiene beats cannabis for better rest in regular users

This study challenges the common assumption that cannabis is an effective sleep aid by demonstrating that sleep hygiene practices may be more beneficial for people who use cannabis regularly. Researchers tracked 85 adults with frequent cannabis use over 14 days, collecting 1,021 daily diary entries about their sleep habits, cannabis use, and sleep quality. The findings show that maintaining good sleep hygiene behaviors—such as avoiding pre-bedtime arousal, using the bed only for sleep or sex, and maintaining consistent sleep schedules—was significantly associated with better sleep outcomes, including longer sleep duration, higher sleep efficiency, and better perceived sleep quality, regardless of cannabis use.

The research revealed some intriguing interactions between substances and sleep patterns. Alcohol combined with cannabis use actually resulted in longer sleep than alcohol alone, suggesting cannabis may amplify alcohol's sedative effects. Additionally, the typically negative relationship between inconsistent sleep schedules and poor sleep quality was significantly reduced on nights when participants used cannabis, implying that cannabis might help offset the sleep-disrupting effects of irregular sleep timing. However, the overall message is clear: sleep hygiene behaviors provide more reliable and controllable improvements to sleep health than relying on substance use alone.

These findings have important practical implications for the millions of people who use cannabis for sleep support. Rather than depending on cannabis as a primary sleep solution, the research supports adopting evidence-based sleep hygiene as the first-line treatment for sleep problems among regular cannabis users. This approach gives users concrete, behavioral tools they can implement—like establishing consistent bedtimes and creating a sleep-focused bedroom environment—that produce measurable improvements in sleep quality, duration, and efficiency.
