Marijuana can make the heart beat faster and can make blood pressure higher immediately after use. It could also lead to increased risk of stroke, heart disease, and other vascular diseases.
A new study presented at the European Society of Cardiology (ESC) Congress 2022 has found that cannabis prescribed for chronic pain in Denmark between 2018 and 2021 was associated with a higher risk of heart rhythm disorders (arrhythmias).
“There are no known cardiovascular benefits for cannabis or cannabidiol, and there may even be some adverse effects, so people should not take these products and think that it will have positive effects on their cardiovascular health,” says Allen, who's also co-author of the American Heart Association's statement on ...
What the research says about CBD and heart disease. CBD's anti-inflammatory and antioxidative properties may be able to reduce risk factors that can lead to heart disease, like high blood pressure. It may also be able to reduce the risk of related conditions, like stroke.
Cardiovascular effects
This is because of complex effects cannabinoids have on the cardiovascular system, including raising resting heart rate, dilating blood vessels, and making the heart pump harder.
Marijuana can make the heart beat faster and can make blood pressure higher immediately after use. It could also lead to increased risk of stroke, heart disease, and other vascular diseases.
For people diagnosed with heart disease, cannabis should be used with extreme caution because cannabis increases the heart's need for oxygen at the same time as it decreases available oxygen supply, which could cause angina (chest pain).
Other studies have suggested that CBD can have a protective effect on the heart: this has been proven in rats after a heart attack and in mice with some of the heart damage associated with diabetes.
However, a 2017 systematic review and meta-analysis found no significant effects of CBD on blood pressure or heart rate in normal circumstances.
A single dose of cannabidiol reduces blood pressure in healthy volunteers in a randomized crossover study.
CBD and its impacts on a protective peptide show that the cannabinoid may reduce lung inflammation and damage. Findings from a recent study reported that cannabidiol (CBD) may improve lung structure and create a potent anti-inflammatory effect through the regulation of apelin, a natural peptide.
Overall, THC and CBD are only detectable in your blood for up to five hours after you take them, though their metabolites can be present for up to a week.
Abstract. Cannabis has been reported to produce acute psychiatric reactions, among these panic anxiety and derealization, which are self-limited. We report on three patients who experienced an initial panic attack during cannabis intake. Anxiety attacks reoccurred after the cessation of intake.
Cannabidiol (CBD) is relatively safe for anxiety, however, at very high doses it may increase anxiety. Tetrahydrocannabinol (THC) is more likely to give you anxiety at a lower dosage and therefore must be monitored very carefully when first starting treatment.
Heart Palpitations and Anxiety. Heart palpitations due to anxiety feel like your heart is racing, fluttering, pounding or skipping a beat. Your heartbeat can increase in response to specific stressful situations. You may also have palpitations due to an anxiety disorder (excessive or persistent worry).
A study based on the neurophysiology of dyspnea (difficulty breathing) and the location of cannabinoid receptors in the central nervous system (CNS) states that cannabinoids will alleviate the unpleasantness of breathlessness in people without causing respiratory depression.
Hemp Cigarettes and your Health
The benefits of smoking hemp cigarettes are much safer than tobacco cigarettes. Tobacco cigarettes contain over 4,000 chemicals, including at least 60 known carcinogens. Hemp cigarettes do not have any of these harmful chemicals.
Hemp seed might slow blood clotting. Taking hemp seed along with medications that also slow blood clotting might increase the risk of bruising and bleeding.
Though it's often well-tolerated, CBD can cause side effects, such as dry mouth, diarrhea, reduced appetite, drowsiness and fatigue. CBD can also interact with other medications you're taking, such as blood thinners. Another cause for concern is the unreliability of the purity and dosage of CBD in products.
Unfortunately, the immunoassay also detects other cannabinoids, such as those in hemp products, that can result in positive tests without the presence of significant levels of 11-nor-9-carboxy THC.
CBD oil and hemp oil are both derived from the plant cannabis sativa, but they're not the same thing, and they won't have the same effects on the body. Hemp oil comes from industrial hemp, which is the term used to designate cannabis grown for food and fiber (not weed).
In general, CBD is absorbed into the bloodstream within 20 minutes to 2 hours depending on the method of delivery. Other variables like the dosage, full spectrum or THC-free, consistency, and quality can also play a role in how quickly you begin to feel the benefits of CBD.
Cannabidiol restores liver function, normalizes 5-HT levels and improves brain pathology in accordance with normalization of brain function. Therefore, the effects of cannabidiol may result from a combination of its actions in the liver and brain.
