Targeted Intervention on Sleep Disorders During Tobacco or Cannabis Cessation Therapy

During a cessation therapy for tobacco or cannabis, sleep disorders are one of the main risk factors of relapse, and a symptom of substance withdrawing. In this study, we make the hypothesis that identifying and managing potential sleep disorders during cessation treatment may contribute to maintain tobacco / cannabis abstinence on the long-term. To evaluate the impact of such intervention, we will conduct a randomised pilot study among patients consulting at two addiction prevention and care centres, for smoking or cannabis use cessation treatment. Control group will benefit of usual care (a multidisciplinary care with individual and group therapies); intervention group will benefit in addition of a systematic screening of sleep disorders, and in case of a diagnosed alteration, they will be addressed to the Chronos centre, for specific care to help them manage and reduce the consequences of their sleep disorders. Participants will be followed over a 6-month period, with visits at 1 and 3 months, to monitor smoking or cannabis cessation, and other criteria associated with their substance use or sleep.
