Study explains THC can help young adults with depression or anxiety but otherwise could worsen sleep problems

Summary

A new study from USC’s Keck School of Medicine found that cannabis can have opposite effects on sleep depending on mental health.

For young adults with anxiety or depression, cannabis use improved sleep, while it worsened sleep for those without these conditions.

Researchers suggest cannabis may mask symptoms of anxiety or depression that disrupt sleep, though it doesn’t address underlying mental health issues.

Experts note that cannabis affects sleep through the endocannabinoid system but warn that high doses or long-term use can lead to dependence and REM sleep reduction.
