Patients with obstructive sleep apnoea (OSA)  considering cannabis use should be aware of cannabis’ cardiovascular risk. The interaction between OSA and cannabis may affect heart rate, blood pressure, and overall cardiovascular health, warranting careful monitoring.

Cardiovascular Implications 

Research indicates that cannabis’ cardiovascular risk may be higher in individuals with OSA due to pre-existing sleep-related stress on the heart. Both short-term and long-term use can influence cardiovascular function. 

Heart Rate and Rhythm 

Heart and cannabis interactions may lead to temporary increases in heart rate or arrhythmias, particularly in sensitive patients. 

Blood Pressure Considerations 

Fluctuations in blood pressure, especially with THC exposure, are notable. Monitoring blood pressure and THC is recommended to reduce potential complications. 

Risk Mitigation 

Patients should discuss cannabis’ cardiovascular risk with their clinicians, especially if they have hypertension or other heart conditions. Adjusting dosage, avoiding high-THC strains, and regular cardiovascular assessment are key strategies. 

Understanding cannabis’ cardiovascular risk is critical for OSA management. Awareness of heart and cannabis and blood pressure and THC ensure safer use, allowing potential benefits of cannabis while minimising cardiovascular complications.
