Continuous positive airway pressure (CPAP) remains the gold standard for sleep apnoea treatment. With the growing use of cannabis, questions arise about potential cannabis and CPAP interaction. Understanding these interactions is essential for patient safety. 

Am I eligible for medical cannabis for pain relief?

Potential Concerns 

While cannabis does not directly interfere with CPAP devices, it may influence sleep patterns, sedation, and airway muscle tone, which could alter treatment effectiveness. Clinicians and patients should be aware of possible issues when combining therapies. 

Altered Sleep Architecture 

Cannabis can modify REM and NREM sleep, potentially affecting how CPAP with cannabis risk manifests during therapy. This may influence the number of apnoea events detected and patient adherence. 

Sedation and Daytime Sleepiness 

Excessive cannabis use could increase sedation, impacting the perceived benefit of CPAP. Monitoring cannabis with CPAP safety ensures patients are not over-sedated while using their devices. 

Airway Muscle Tone 

Cannabinoids may influence upper airway tone, which could theoretically modify CPAP pressure needs. Awareness of cannabis and CPAP interaction can guide clinicians in optimising therapy settings. 

Current evidence suggests minimal direct device interference, but CPAP with cannabis risk remains relevant for sleep quality and adherence. Considering cannabis with CPAP safety helps maintain effective OSA management while using cannabis therapeutically.
