CBD alone doesn't cause heart problems. However, CBD is broken down and metabolized in the liver. During this process, it can interfere with medications for any heart condition you have. This can cause liver problems or interfere with the effectiveness of any medication you are taking.
When you use CBD oil, your liver breaks it down. During this process, it could interfere with medications for heart failure or other heart conditions. Just because a supplement is “natural” doesn't mean it's safe, says Lundgren. One concern is the potential for interactions with other medications, including blood thinners, antidepressants, antipsychotics, antiarrhythmics for heart rhythm abnormalities, and statin drugs, which lower cholesterol levels.
Research is ongoing on the use of purer forms of CBD for a variety of conditions, including heart and circulatory diseases and, in particular, diseases of the heart muscle, such as myocarditis and some types of cardiomyopathy. Isolation of the chemical structure of CBD revealed that it is a classic cannabinoid closely related to cannabinol and Δ−9-tetrahydrocannabinol (THC). Acutely, THC also appears to stimulate the sympathetic nervous system, which is responsible for the “fight or flight” response, resulting in a higher heart rate, increased oxygen demand by the heart, higher blood pressure at bedtime, and dysfunction within the artery walls. Another concern about older adults using cannabis is the potential for interactions with other medications, including blood thinners (blood thinners), antidepressants, antipsychotics, antiarrhythmics for heart rhythm abnormalities, and statin medications, which lower cholesterol levels.
For people diagnosed with heart disease, cannabis should be used with extreme caution, as cannabis increases the heart's need for oxygen while decreasing the supply of available oxygen, which could lead to angina (chest pain). Taken together, these data suggest that in vivo treatment with CBD has significant cardioprotective effects, which may be through direct action on the heart or through a general anti-inflammatory and antioxidant mechanism (see Table. In vivo, CBD treatment doesn't seem to have any effect on blood pressure or resting heart rate, but it does reduce cardiovascular response to various types of stress. There is a lot of marketing that says CBD is a “miracle of the modern era”; however, marketing has actually surpassed the evidence of its effectiveness.
The two most prevalent types are tetrahydrocannabinol (THC), which is primarily responsible for the mind-altering properties sought by recreational users, and cannabidiol (CBD), which has no psychoactive effect. This is due to the complex effects that cannabinoids have on the cardiovascular system, such as raising the resting heart rate, dilating blood vessels, and causing the heart to pump harder. THC also appears to stimulate the sympathetic nervous system, which is responsible for the fight-or-flight response, resulting in a higher heart rate, increased oxygen demand by the heart, higher blood pressure while lying down, and dysfunction within the artery walls. CBD oil should be studied in randomized clinical trials in humans, not animals, before it can be considered safe or effective for heart failure, says Lundgren.
One of the few things scientists know for sure about marijuana and cardiovascular health is that people with established heart disease who are under stress develop chest pain faster if they have been smoking marijuana than otherwise. CBD is the latest health craze to sweep high street, with claims it can help with everything from chronic pain and inflammation to anxiety. But because these studies are often based on findings in a laboratory or in animals, not humans, we can't be sure that CBD benefits the human heart. .
