Does CBD affect blood pressure?

In France, high blood pressure, commonly known as hypertension, is a serious health concern. According to statistics, about one-third of the adult population in France has hypertension, and this number continues to rise. This medical condition, which is often silent and asymptomatic, can have serious health consequences if not properly managed.


Blood pressure is the force exerted by blood on the walls of the arteries as it is pumped by the heart. Normally, balanced blood pressure is essential for our bodies to function properly. However, when blood pressure becomes too high, it can damage blood vessels, the heart, the kidneys, and other vital organs. The consequences of high blood pressure can include cardiovascular disease, strokes, kidney failure, and other serious complications.


Faced with this issue, many people are seeking alternative approaches to regulate their blood pressure. Cannabidiol, better known as CBD, has recently attracted growing interest as a potential blood pressure reducer. CBD is a compound naturally found in the cannabis plant, but it does not produce the psychoactive effects associated with marijuana. This raises the question: Could CBD influence blood pressure and offer an effective alternative to conventional treatments? 

Blood Pressure: A Major Health Issue

Blood pressure, also known as arterial pressure, plays a crucial role in our health and well-being. It is a key indicator of heart and vascular function, reflecting the force exerted by blood on the walls of the arteries as it is pumped by the heart. Understanding blood pressure is essential, as high or low levels can have serious health consequences.


Balanced blood pressure is necessary to ensure proper blood circulation and to supply oxygen and essential nutrients to all the body’s organs and tissues. Blood pressure readings are expressed as two values: systolic pressure and diastolic pressure. Systolic pressure is the force exerted on the arteries when the heart contracts to pump blood, while diastolic pressure is the residual pressure when the heart is at rest between beats.


High blood pressure, known as hypertension, is a particular cause for concern. Hypertension is often called the “silent killer” because it can go unnoticed for long periods of time, with no obvious symptoms. However, over time, untreated hypertension can lead to serious complications, including cardiovascular disease, strokes, kidney failure, and other health problems.


On the other hand, low blood pressure, known as hypotension, can also cause health problems such as dizziness, excessive fatigue, and poor blood circulation. It is therefore essential to maintain balanced blood pressure to preserve our overall well-being.

CBD: Does It Have the Potential to Lower Blood Pressure?

While research on the potential effect of CBD on blood pressure is still limited, opinions among healthcare professionals differ. Dr. Sunny Intwala, a cardiologist at Nuvance Health in Poughkeepsie, New York, says he does not recommend CBD as a means of lowering blood pressure due to the lack of studies. Until further research is conducted, Dr. Intwala cannot recommend its use for blood pressure management.
 

According to Dr. Intwala, however, there is solid scientific research on other methods of lowering blood pressure, such as a heart-healthy diet, regular exercise, meditation, and, when appropriate, prescription medications. He therefore feels confident in recommending these approaches over CBD.


Dr. Robert Page II, a doctor of pharmacy and professor of clinical pharmacy at the University of Colorado, is frequently asked about the use of CBD for heart health. While he acknowledges the potential health benefits of CBD, he echoes Dr. Intwala’s remarks by stating that there is insufficient scientific evidence to demonstrate the benefits of CBD on blood pressure.


Dr. Page explains that the theory behind CBD’s potential cardiovascular benefits is based on CBD receptors binding to immune cells, which could have an anti-inflammatory effect on blood vessels. However, more scientific evidence is needed to confirm or refute this theory, which is just one of several potential mechanisms that researchers could explore.


The two experts, Dr. Intwala and Dr. Page, also point out that angiotensin-converting enzyme (ACE) inhibitors, which block the production of angiotensin II (a hormone that constricts blood vessels), are backed by robust scientific research demonstrating their ability to safely lower blood pressure.


However, some healthcare providers believe that CBD may actually help lower blood pressure. Dr. Chiti Parikh, executive director of the Center for Integrative Health and Wellness at Weill Cornell Medicine and New York-Presbyterian, cites studies showing a decrease in resting blood pressure after taking CBD. In addition, CBD may help counteract the effects of stress, which can lead to an increase in blood pressure.


Dr. Parikh cites a small study conducted by the American Society for Clinical Investigation, in which nine healthy men received either 600 milligrams of CBD or a placebo before undergoing a mental stress test. The researchers measured their blood pressure before and after the test using a finometer (a device that measures blood pressure in the finger via heart rate) and a laser Doppler (an imaging device also used to measure blood pressure). The men who took CBD had lower blood pressure than those who took the placebo, particularly immediately after the stress test.


CBD may potentially help lower blood pressure by relieving symptoms of anxiety, which can lead to an increase in blood pressure. It binds to certain receptors in the brain and arteries, causing them to relax. However, further research is needed to confirm this potential effect.

Side Effects and Risks Associated with Using CBD for High Blood Pressure

Experts agree that using CBD to lower blood pressure may carry certain risks and side effects. Dr. Parikh points out that, unlike prescription medications with specified dosages, it is still unclear what dose of CBD has what effect on a person's blood pressure.


In addition, CBD can interfere with other medications. Dr. Page explains that people aged 65 or older take an average of four to five medications a day. Those with heart failure take an average of six to ten medications a day. Therefore, any medication or dietary supplement added to this list can lead to interactions.


Dr. Page also points out the lack of regulation regarding CBD products, which makes it difficult to know the exact potency and quality of the product you might be taking.


Some people may experience adverse side effects associated with CBD. These can include fatigue, diarrhea, changes in appetite or weight, and mood swings.


It is important to note that the side effects and risks associated with CBD use can vary from person to person. Everyone reacts differently to substances, and it is recommended that you consult a healthcare professional before starting any new treatment or dietary supplement.
 

It should also be noted that the available information on CBD and its effects on blood pressure is still limited. Further research is needed to better understand the interactions, effective doses, and potential side effects associated with the use of CBD for hypertension.

Who should I consult about CBD and blood pressure?

If you have specific questions about using CBD for blood pressure, experts recommend consulting a cardiologist or primary care provider who can discuss potential risks and recommend other, more beneficial measures, such as dietary and lifestyle changes. During your appointment with your healthcare provider, explain why you’re considering using CBD for blood pressure so they can offer personalized advice.
 

Cardiologists are specialists in cardiovascular health and are therefore well-positioned to assess the potential risks of using CBD, particularly in people with high blood pressure or other heart conditions. They can take into account your overall health, medical history, and other medications you are currently taking to provide you with appropriate advice.
 

Your primary care physician can also play an important role in the decision-making process. They are familiar with your medical history and can provide you with information specific to your situation. They can also refer you to other specialists if necessary, based on your individual needs.
 

It is essential to work closely with your healthcare provider to assess the potential benefits and risks of using CBD for your blood pressure. They can provide you with recommendations based on scientific evidence and help you make informed decisions.
 

It is important to note that CBD can interact with certain medications, so it is crucial to inform your healthcare provider of all the medications you are taking—including CBD—to avoid potentially dangerous interactions.
