Who could benefit from this research
✓Could help
Ideal candidates are adults aged 21 and older who experience both insomnia and problematic cannabis use.
✕Less likely to help
Patients who do not experience insomnia or problematic cannabis use would likely not receive direct benefit from this specific intervention.
What this research studies
Many adults who use cannabis regularly also struggle with insomnia, and sleep problems can make it harder to cut back on cannabis. This project builds on earlier work that showed a tailored talk therapy, called Cognitive Behavioral Therapy for insomnia (CBTi), delivered remotely, helped people sleep better and use less cannabis. We want to understand how this therapy works by looking at the body's natural sleep regulation system. Our goal is to offer a new way to support individuals who want to improve their sleep and manage their cannabis use.
Why it matters
Potential benefit: If successful, this approach could provide an effective, non-medication treatment for insomnia that also helps reduce problematic cannabis use.
How similar studies have gone: A previous pilot trial by this group showed promising results, indicating that a tailored CBTi improved insomnia and reduced cannabis use.
