Key Points:
- A long-term Northwestern University study tracked about 1,300 adults over 35 years, finding that regular marijuana users experienced more frequent awakenings and less deep sleep, according to data from wrist-actigraphy monitors.
- Despite disrupted sleep patterns, participants did not report feeling less rested, likely because brief nighttime arousals often go unnoticed.
- A systematic review of nine clinical trials found that medical cannabis provides little to no measurable benefit for chronic sleep disorders.
- Experts caution that while there is a strong correlation between cannabis use and disturbed sleep, these observational studies do not establish a direct causal relationship.
- Millions of Americans continue to use marijuana as a sleep aid, even as scientific evidence increasingly suggests it may impair rather than improve sleep quality.
