Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will compare the efficacy of telemedicine-delivered cognitive behavioral therapy for insomnia tailored for people using cannabis for sleep (CBTi-CB-TM) to telemedicine-delivered sleep hygiene education (SHE-TM) on sleep, cannabis use, and daytime functioning. We will also evaluate the effects of CBTi-CB-TM on fundamental sleep regulatory system - homeostatic sleep drive - and its association with clinical outcomes.
