• how does marijuana impact sleep

  • Sources:

    Marijuana, specifically THC, has been shown to affect sleep in several ways. While it can help you fall asleep faster, it often disrupts the natural architecture of sleep, particularly REM sleep. THC blocks REM sleep, which is crucial for dreaming and restorative rest. When people stop using THC, they often experience a rebound in REM sleep, leading to vivid dreams as the brain attempts to recover lost sleep stages 1 2.

    Regular use of THC can also lead to the development of tolerance, requiring higher doses to achieve the same sleep-inducing effects and potentially leading to dependency. Upon cessation, users might experience rebound insomnia, which is a common withdrawal symptom from cannabis 2 3.

    Conversely, CBD, another compound found in cannabis, might have some beneficial effects on sleep without the detrimental impact on REM sleep. CBD is suggested to reduce anxiety and lower core body temperature, both of which can facilitate better sleep. However, the overall impact of CBD on sleep is still being researched, and it does not produce the psychoactive effects associated with THC 4 3.
