How Does Cannabis Impact Sleep?

Certain compounds in cannabis, like THC, may promote relaxation and potentially lead to increased total sleep time. However, its impact on specific sleep stages, like deep sleep and REM, is not uniform.

Effects on Deep Sleep

Some research suggests that cannabis might reduce deep sleep time, potentially affecting sleep quality.

Effects on REM Sleep

Similarly, while cannabis can induce sleep, its effects on REM sleep can be variable, with some studies indicating it might reduce REM time.
