Medical Cannabis for Insomnia

Does medical cannabis improve sleep in people with insomnia?

The review, published October 13, assessed cannabis-based treatments against placebo or another medicine. Evidence certainty was low or very low, so the findings do not establish that every cannabis preparation is ineffective. They show that dependable treatment benefits remain unproven.

Trials were small, used different products and followed participants for limited periods. These differences make results difficult to compare and leave long-term benefits and harms unresolved. Reported adverse effects included dizziness and dry mouth; older adults and people with additional illnesses were inadequately represented.

What treatment has stronger support for chronic insomnia?

CBT-I addresses thoughts and behaviors that perpetuate sleep difficulties. Treatment can combine strategies that strengthen the association between bed and sleep, adjust time spent in bed, reduce sleep-related worry and support relaxation. It is a structured treatment tailored to the individual. The American Academy of Sleep Medicine's guideline supports this approach for adults with chronic insomnia. [AASM clinical practice guideline](https://pmc.ncbi.nlm.nih.gov/articles/PMC7853203/).

Basic sleep advice alone is often insufficient: the guideline recommends against using sleep hygiene as the sole treatment. Access can include appointments in person, telehealth or suitable digital programs. For patients considering cannabis because other approaches have disappointed them, discussing access to structured CBT-I provides a practical next step.
