Can cannabis use affect my sleep disorders based on genetic studies?
Research indicates that the genetic factors influencing cannabis use overlap with those for sleep problems. A large genetic analysis found that people with a genetic predisposition to cannabis use also show higher risks for clinical insomnia and reduced nighttime physical activity 2.
What the research says
A meta-analysis of over 378,000 individuals identified shared genetic signals between cannabis use and clinical insomnia. This study found a near-perfect overlap in genetic markers at specific locations, such as SLC39A8 and CADM2 2. The research also noted that genetic factors linked to cannabis use are strongly connected to genes regulating sleep and neurons in the brain 2.
These genetic links extend to specific behaviors. The study observed positive genetic correlations with insomnia and medication usage for sleep, alongside negative correlations with morningness chronotype and daytime activity 2. This suggests that the genetic architecture of cannabis use is heavily enriched within the central nervous system 2.
While other research discusses sleep disorders in the context of physical health like gait quality in older adults or glymphatic dysfunction in the brain 34, the direct genetic connection to cannabis use specifically points to insomnia and sleep regulation genes 2.
