How Does Cannabis Work as a Sleep Aid?

It is believed that the sleep-promoting effects of cannabinoids are due to their interactions with cannabinoid receptors in the brain. When cannabinoids bind to these receptors, they send Cannabiz messages to increase levels of sleep-promoting adenosine and suppress the brain’s arousal system. Together, these effects may help cannabis users feel sedated or sleepy.

Cannabis has several different active compounds, including tetrahydrocannabinol (THC) and cannabidiol (CBD). While THC typically acts as a sedative, it can have a stimulating effect for some people, especially for those who are new to using cannabis or taking higher doses. In these cases, using cannabis before bed may result in a longer time falling asleep. CBD appears to promote alertness at lower doses, and sleepiness at higher doses.

Both CBD and THC may also have benefits for chronic conditions that interfere with sleep. However, the effects of the two compounds together may depend on the dose and timing.

For example, synthetic forms of THC have shown potential for treating obstructive sleep apnea, reducing PTSD-related nightmares, and improving sleep for people living with chronic pain. CBD, on the other hand, may reduce symptoms of REM sleep behavior disorder and excessive daytime sleepiness.

When using cannabis as a sleep aid, the effects you feel may depend on the type of cannabis you are using. Cannabis has higher concentrations of THC, the primary psychoactive component. Hemp plants have higher levels of CBD.
