Orexin blockers for cannabis withdrawal and use in a controlled inpatient study

Official title: Effects of the Orexin Dual Receptor Antagonist Suvorexant on Cannabis Withdrawal and Self-Administration: a Controlled Inpatient Human Laboratory Study in People with Cannabis Use Disorder

Funded at University of Kentucky · NIH-11337805 · Data updated 2026-11-12

A study will test whether blocking orexin receptors with suvorexant helps people with cannabis use disorder manage withdrawal and reduce self‑ar mg behavior in a supervised inpatient setting.

Who could benefit from this research

Could help

Adults with cannabis use disorder who can participate in an inpatient laboratory study.

Less likely to help

Individuals without cannabis use disorder or those unable to participate in an inpatient setting may not benefit.

What this research studies

This inpatient study will enroll adults with cannabis use disorder to test how suvorexant, a dual orexin receptor antagonist, affects withdrawal symptoms and cannabis self‑administration. Participants will be closely monitored in a controlled laboratory environment to measure cravings, withdrawal, and cannabis intake, using standardized assessments and biological samples. The goal is to see if targeting the orexin system can make quitting cannabis easier and reduce the chance of relapse.

Why it matters

Potential benefit: If successful, the approach could lead to new treatment options that ease withdrawal and reduce cannabis use.

How similar studies have gone: Early clinical data suggest orexin antagonists may help with withdrawal in other substances, supporting exploration in cannabis use.
