Understanding the Heart Risks of Cannabis Use
Share
Cannabis, also known as marijuana, is used for both medical and recreational reasons. As more countries legalize it, many people assume it's completely safe. But a new study shows that cannabis use might raise the risk of serious heart problems.
What Did the Study Look At?
This study reviewed 24 research papers that included over 430 million people. It looked at whether using cannabis increases the chances of major heart-related issues. These issues include heart attacks, strokes, and even death caused by heart disease. The researchers combined data from many sources to get a clearer picture of the risks.
Key Findings You Should Know
Here’s what they found:
- Stroke risk was 20% higher in people who used cannabis
- Heart attack risk (acute coronary syndrome) was 29% higher
- Death from heart disease was more than twice as likely (a 110% increase)
In other words, cannabis users had significantly more heart problems than non-users.
Why Is This Happening?
Cannabis contains chemicals like THC and CBD. THC can affect the heart by:
- Increasing heart rate
- Raising blood pressure
- Narrowing blood vessels
These effects put more strain on the heart. Over time, this may lead to heart attacks or strokes, especially in people with other risk factors like smoking, high cholesterol, or high blood pressure.
Who Is Most at Risk?
Young men who use cannabis regularly were most commonly affected. Many studies found that people under 40 had a higher chance of having a heart attack if they used cannabis, especially those who used it often. Also, the risk seemed to be higher for people who used stronger forms of cannabis or combined it with tobacco or other drugs.
What About Medical Cannabis?
Only one of the 24 studies looked specifically at medical cannabis. Even in that study, users had a higher risk of heart problems. However, more research is needed to understand the differences between recreational and medical cannabis when it comes to heart health.
Should You Be Worried?
If you use cannabis, especially regularly or in large amounts, it’s important to be aware of these risks. Even though many people see cannabis as natural or harmless, it can still affect your body in ways that aren't immediately obvious. This is especially true for your heart and blood vessels.
What Can You Do?
Here are some practical tips if you're concerned about your heart health and cannabis use:
- Talk to your doctor before using cannabis, especially if you have high blood pressure, heart disease, or a family history of heart problems
- Avoid mixing cannabis with tobacco or alcohol, which can raise the risk even more
- Know your dosage if using medical cannabis and stick to your prescribed amount
- Watch for warning signs like chest pain, dizziness, or shortness of breath after using cannabis
- Make healthy lifestyle choices like regular exercise, a balanced diet, and quitting smoking
Final Thoughts
Cannabis use is becoming more common, but it's not without risks. This new research clearly shows that using cannabis may increase your risk of serious heart problems. Being informed and cautious, especially if you already have other risk factors, can help you stay safe.
If you’re using cannabis, consider how it fits into your overall health picture. Always check with a healthcare professional if you have concerns. Your heart will thank you.
