How Does Cannabis Affect Blood Pressure and Heart Rate in Chronic Pain Patients? 

Author: Dr. Clarissa Morton, PharmD

Alongside pain relief, patients often ask how cannabis may influence the heart and circulation. Research shows that cannabis cardiovascular effects include temporary changes to both blood pressure and heart rate, which may be important for patients with underlying conditions. 

For people with general chronic pain, understanding these effects ensures treatment is used safely and with proper medical oversight. 

Cardiovascular Responses to Cannabis 

Cannabis interacts with the body’s endocannabinoid system, influencing circulation and heart activity. 

Blood Pressure Changes 

One common finding is blood pressure changes, where cannabis may initially cause a mild rise followed by a drop. For some patients, this can lead to dizziness, particularly when standing up quickly. 

Cannabis Heart Rate  

The impact of cannabis on heart rate often includes a temporary increase in beats per minute. While usually harmless for healthy individuals, this may be more concerning for those with pre-existing heart conditions. 

Cardiovascular Safety 

Doctors emphasise cardiovascular safety when prescribing cannabis, especially for older patients or those with hypertension. Monitoring helps ensure any risks are managed appropriately. 

In summary, while cannabis can support pain relief, cannabis cardiovascular effects require attention. Patients with heart concerns should always consult their doctor before beginning treatment.
