Can Marijuana Help You Sleep? - Addiction/Recovery eBulletin

NO MORE MELATONIN –

Oct. 21, 2025 – Cannabis contains dozens of compounds such as cannabidiol (CBD), which does not cause the “high” typically associated with marijuana, and tetrahydrocannabinol (THC), which does have mood- and mind-altering effects. Products that consist primarily of CBD, along with low doses of THC, may help some people fall asleep faster and stay asleep longer.

Research on cannabis and sleep remains somewhat inconclusive, partly because strains, potency, frequency and length of use, as well as the underlying health of participants, have varied from study to study, making it difficult to draw clear conclusions. Some studies have suggested that cannabis promotes better sleep in people with anxiety issues or chronic pain, for instance. But it could be that participants slept better because it eased their symptoms, some experts said.

Researchers have started to focus on cannabis use for sleep issues only more recently.

Participants with sleep troubles who used CBD slept better than those given a placebo, according to a 2024 randomized clinical trial.

The addition of cannabinol (CBN) and cannabichromene (CBC) — two other THC-free compounds — however, did not have notable effects, though CBN has shown promise as a sleep aid in other research.
