Summary

This pilot study tests whether screening and treating sleep disorders during tobacco or cannabis cessation therapy helps people stay abstinent longer. 80 participants will either get usual care or extra sleep-focused care. The study follows them for 6 months to see if addressing sleep issues reduces relapse.

What this could mean

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

Active substance
screening and management of sleep disorders (cognitive behavioural therapy, image rehearsal therapy)
What this could lead to
If it works, this could point toward a simple way to improve quit rates for tobacco or cannabis by addressing sleep problems during withdrawal.
What could go wrong
This is a small pilot study with only 80 people, so results may not apply widely. The intervention adds extra steps, and sleep treatment may not directly improve abstinence.
