First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 5 times
Summary
This study tests whether taking dronabinol (a cannabis-derived medication) before bed can help people with obstructive sleep apnea use their CPAP machine more consistently. Researchers will also check if combining CPAP with dronabinol improves sleep quality and blood pressure. The study involves 72 adults aged 21-70 with moderate to severe sleep apnea.
