Can Cannabis Lower Your High Blood Pressure?
Hypertension, or high blood pressure, is a common condition affecting about one in three adults in the United States. It occurs when the force of blood against artery walls is too great, which can damage blood vessels and increase the risk of stroke and heart attack.
There are many factors that can contribute to hypertension, such as poor diet, stress, physical inactivity, alcohol, and tobacco use. But what about cannabis? Can cannabis lower your high blood pressure? How does it affect your heart health?
What Is Blood Pressure and Why Is It Important?
Blood pressure is measured by two numbers: systolic and diastolic. Systolic pressure is the pressure when your heart beats and pumps blood, while diastolic pressure is the pressure when your heart rests between beats.
A normal blood pressure range is below 120/80 mmHg, while a high blood pressure range is above 140/90 mmHg. If your blood pressure is consistently high, it can cause damage to your arteries, heart, brain, kidneys, and eyes over time.
How Does Cannabis Affect Blood Pressure?
Cannabis can affect blood pressure and heart rate in different ways depending on the dose, strain, mode of consumption, and frequency of use.
Short-Term Effects of Cannabis on Blood Pressure
One of the effects that cannabis can have on the cardiovascular system is to lower blood pressure by relaxing blood vessels and inducing hypotension. Hypotension is a condition where blood pressure is lower than normal, which can cause symptoms such as dizziness, fainting, blurred vision, and nausea. Hypotension can occur when cannabis activates the cannabinoid receptors in the brain and peripheral tissues, which are involved in regulating blood pressure and heart rate.
However, not all cannabis users experience a decrease in blood pressure. Some users may experience an initial increase in blood pressure and heart rate, followed by a decrease in blood pressure. This can happen when cannabis stimulates the sympathetic nervous system, which is responsible for the fight-or-flight response. The sympathetic nervous system can increase blood pressure and heart rate by constricting blood vessels and increasing cardiac output. This can cause symptoms such as anxiety, palpitations, chest pain, and sweating.
The short-term effects of cannabis can vary depending on several factors, such as:
- The dose of cannabis: Higher doses of cannabis can have more pronounced effects on blood pressure and heart rate than lower doses.
- The strain of cannabis: Different strains of cannabis have different ratios of cannabinoids, such as THC and CBD. THC is the main psychoactive component of cannabis that can raise or lower blood pressure and heart rate depending on the dose. CBD is a non-psychoactive component of cannabis that can counteract some of the effects of THC and may have a protective effect on the cardiovascular system.
- The mode of consumption: Smoking or vaping cannabis can have faster and stronger effects on blood pressure and heart rate than ingesting or applying it topically. This is because smoking or vaping delivers cannabinoids directly into the bloodstream through the lungs, whereas ingesting or applying it topically involves metabolism by the liver and other organs before reaching the bloodstream.
- The frequency of use: Chronic or frequent cannabis users may develop tolerance to some of the effects of cannabis on blood pressure and heart rate. This means that they may need higher doses of cannabis to achieve the same effects as before or may experience less noticeable effects than occasional or new users.
Long-Term Effects of Cannabis on Blood Pressure
Some studies suggest that chronic cannabis consumption can lower blood pressure over time by reducing inflammation, oxidative stress, and arterial stiffness. These are factors that can contribute to hypertension and cardiovascular disease. Chronic cannabis use may also lower blood pressure by modulating the endocannabinoid system, which is a network of receptors and molecules that regulate various bodily functions, including blood pressure and heart rate.
However, other studies suggest that chronic cannabis use can increase blood pressure over time by causing endothelial dysfunction, which is a condition where the inner lining of blood vessels becomes damaged or impaired. Endothelial dysfunction can impair blood flow and increase the risk of hypertension and cardiovascular disease. Chronic cannabis use may also increase blood pressure by interfering with the renin-angiotensin system, which is a hormonal system that regulates blood pressure and fluid balance.
The long-term effects of cannabis use may depend on several factors, such as:
- The age of onset: Cannabis use during adolescence or early adulthood may have more detrimental effects on blood pressure than later onset. This is because cannabis use during these developmental stages may interfere with brain maturation and neuroplasticity, which are processes that shape brain structure and function throughout life.
- The duration and frequency of use: Prolonged and frequent cannabis use may have more negative effects on blood pressure than occasional or short-term use. This is because prolonged and frequent cannabis use may cause more cumulative damage to the cardiovascular system or induce more physiological changes that affect blood pressure regulation.
- The presence of other risk factors: Cannabis use may interact with other risk factors for hypertension or cardiovascular disease, such as genetics, lifestyle, diet, stress, obesity, diabetes, smoking, alcohol use, or other substance use. Cannabis use may exacerbate or mitigate some of these risk factors depending on the individual and the context.
How Can You Use Cannabis Safely If You Have High Blood Pressure?
If you have high blood pressure and want to use cannabis for medical or recreational purposes, you should consult with your doctor first. Your doctor can advise you on the potential benefits and risks of using cannabis for your condition and monitor your blood pressure and heart health regularly. You should also follow these tips to use cannabis safely:
- Choose low-THC strains or products that contain more CBD than THC. CBD is a non-psychoactive cannabinoid that may help reduce anxiety and stress levels and relax the blood vessels.
- Avoid vaping or smoking marijuana as these methods can deliver high doses of THC quickly and increase your heart rate and blood pressure. Instead, opt for edibles or tinctures that have a slower onset and longer duration of effects.
- Start with low doses and go slow. Cannabis affects everyone differently and you may be more sensitive to its effects if you have high blood pressure. Start with a small amount and wait at least an hour before taking more.
- Avoid mixing cannabis with alcohol or tobacco as these substances can worsen your blood pressure and heart health.
- Stay hydrated and avoid caffeine as these can also affect your blood pressure.
Conclusion
Cannabis can have different effects on blood pressure depending on various factors such as dose, strain, mode of consumption, frequency of use, and individual characteristics. If you have high blood pressure and want to use cannabis for medical or recreational purposes, you should talk to your doctor first and follow some safety tips to reduce the potential risks to your heart health.
Cannabis is not a substitute for proper blood pressure management and you should always follow your doctor’s advice on how to lower your blood pressure and prevent complications.
FAQs
Indica and sativa are two main types of cannabis plants that have different characteristics and effects. Indica strains tend to have more CBD than THC, while sativa strains tend to have more THC than CBD. CBD is a non-psychoactive compound that may have anti-inflammatory, anti-anxiety, and neuroprotective properties. THC is a psychoactive compound that may have analgesic, anti-nausea, and appetite-stimulating properties.
Some people believe that indica strains are more relaxing and sedative than sativa strains, which are more uplifting and energizing. However, the effects of cannabis can depend on many factors beyond the type of plant, such as cannabinoid profile, terpene profile, dosage, method of consumption, and individual response. Some people may find that indica strains help them lower their stress levels and improve their sleep quality, which can benefit their blood pressure. Others may find that sativa strains help them increase their physical activity and mood levels, which can also benefit their blood pressure.
However, some people may experience adverse effects from either type of cannabis, such as increased anxiety, paranoia, or heart rate. People who have hypertension or heart problems should be cautious when using cannabis and consult a doctor before trying any new products or strains.
There are many factors that can affect blood pressure, such as stress, diet, exercise, medication, and genetics. Some lifestyle changes that can help lower blood pressure immediately include:
