CBD Effects on the Heart: What Does the Science Say?

WRITTEN by Edd

 | Last revised

CBD has a number of effects on the body that can influence your heart health and may reduce your risk of heart disease.

These include reducing blood pressure and cholesterol, fighting inflammation of blood vessels, and aiding metabolism and weight management.

The interactions between CBD and cardiovascular health are in the early stages of research, and many of the exact mechanisms are not fully understood.

Find out what science has discovered so far.

Does CBD Affect the Heart?

CBD can offer many health benefits and relief from a wide range of symptoms and conditions.

However, its effects may be a little more complex when it comes to the heart.

While some of its effects can benefit the health of your heart, there are some concerns that it could also have some negative effects.

It is important to understand that research into the health benefits of CBD and cannabis is still fairly thin on the ground.

It is simply too early to make any definitive statements about how CBD affects the heart, and in many cases, studies have only been conducted on animals, not humans.

Nonetheless, emerging research is beginning to uncover a number of potential effects that CBD could have on heart health.

CBD is an Anti-Inflammatory

Inflammation is a key contributing factor in many diseases and health conditions affecting the heart, such as coronary heart disease, high blood pressure, and strokes.

Several studies have indicated that CBD can reduce inflammation, which suggests that CBD could help treat and prevent heart problems related to inflammation. [1]

CBD Can Reduce Stress

CBD can lower your levels of cortisol, one of the main hormones involved in making you feel anxious or stressed.

Stress, especially chronic stress, can raise your blood pressure and heart rate. As a result, CBD might be useful for preventing high blood pressure due to stress.

CBD Effects On Heart Rate

CBD has not been shown to directly influence your resting heart rate. However, it can help to reduce stress levels down.

Stress, especially chronic stress, can cause your heart rate to increase and raise your blood pressure.

Does CBD Elevate Your Heart Rate?

CBD does not elevate your heart rate, or at least there has not been any study suggesting that it does.

CBD does not directly lower your heart rate. Instead, it can reduce some of the effects of stress, including an increased heart rate and blood pressure. [2]

In other words, CBD may help reduce an elevated heart rate caused by stress, but it does not lower your resting heart rate under normal conditions.

However, if you smoke CBD flower or vape CBD e-liquids, these administration methods may raise your heart rate because they interfere with your oxygen supply.

Can CBD Cause An Irregular Heartbeat?

Some studies suggest cannabis use can contribute to an irregular heartbeat and other cardiovascular problems.

However, these mostly focus on cannabis as a whole rather than CBD as an isolated cannabinoid.

Furthermore, they often focus on people who are suffering health issues due to heavy cannabis smoking.

Smoking, especially smoking with tobacco, can introduce additional heart health issues that are not necessarily caused by CBD, THC, or other cannabinoids.

Less research is available when it comes to isolated CBD. However, one study on rats suggested that CBD may be able to help treat or prevent heart arrhythmia.

A study on hospitalised cannabis users found that patients with arrhythmia suffered worse outcomes than non-cannabis users.

However, this study did not distinguish between cannabinoids or administration methods, so these effects might not be related to CBD oil. [3]

CBD and Heart Medications: Can They Be Taken Together?

CBD oil can interfere with the effects of some medications. This includes medications used to treat various heart conditions.

These include:

  • Warfarin
  • Some statins
  • Calcium channel blockers
  • Beta-blockers
  • Nitrates

If you are taking any of the medications listed above, CBD could prevent your medication from having its intended effect or cause you to experience negative side effects. [4]

Due to the lack of trials and studies with human subjects, CBD could have other interactions with medications that are not known yet.

If you are taking any prescribed drugs for your heart or any other health condition, you should always consult a doctor before adding CBD oil to your health regimen.

Research Into The Effects Of CBD On Your Heart Are Shows Promising Early Results

CBD may not directly improve heart health. However, it affects many factors that can contribute to better cardiovascular health.

For example, there are signs that point toward CBD lowering blood pressure and heart rate in stressful situations and reducing inflammation in the cardiovascular system.

As a result, CBD may indirectly help your body manage and prevent conditions that can negatively impact your heart health.

Accordingly, you should not use CBD to treat a heart problem instead of seeing a doctor, and you should always get medical advice before taking CBD if you have prescribed heart medications.
