Summary

This study tests whether a type of talk therapy for insomnia, delivered via telemedicine, can improve sleep and reduce cannabis use in adults who have trouble sleeping and use cannabis regularly. 200 participants will be randomly assigned to either cognitive behavioral therapy for insomnia or sleep hygiene education. The goal is to see if better sleep leads to less cannabis use and better daytime functioning.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Cognitive Behavioral Therapy for insomnia (CBTi-CB-TM) and Sleep Hygiene Education (SHE-TM)
What this could lead to: If successful, this could provide an effective behavioral treatment for insomnia that also helps reduce cannabis use, offering a non-drug alternative for people who use cannabis to sleep.
What could go wrong: This is a relatively small, early-stage study comparing two behavioral interventions. Results may not apply to all cannabis users, and the effect on cannabis use may be modest or short-lived.
