These are the lungs of a 10-year marijuana user. They are not supposed to look like this. People think it’s harmless, but this is what long-term use actually does to your body. Smoke at your own risk.

If you think weed is harmless, think again. A major new study published in the Journal of the American College of Cardiology (JACC) suggests that adults under 50 who use marijuana are six times more likely to have a heart attackthan people who don’t use it.

The research looked at over 4.6 million adults and found some pretty worrying links between cannabis and heart problems.

“This isn’t about demonizing marijuana — it’s about understanding the risks,” researchers said in the study. “Heart and blood vessel health can be affected by regular cannabis use.”

💔 What the Study Found

Here’s the simple version:
People who use weed — especially young adults — could face serious heart problems down the line.

According to the study:

  • Marijuana users under 50 are 6x more likely to have a heart attack.
  • They’re 4x more likely to have a stroke.
  • 3x more likely to face major heart or blood vessel problems.
  • 2x more likely to develop heart failure.

These numbers shocked a lot of experts because weed is often seen as a “safe” drug compared to cigarettes or alcohol. But the truth is, it may put more stress on your heart than you think.

“ Well after 15 years of using marijuana almost daily, I have to stop. I have something called Cannabinoid Hyperemesis Syndrome which makes me feel deathly ill. As of today, I am 7 days sober. Here's to new beginnings I guess.”

🧠 What Could Be Happening Inside Your Body

Researchers believe marijuana might affect the heart by:

  • Increasing heart rate and blood pressure
  • Lowering oxygen levels in the blood
  • Causing inflammation in blood vessels
  • Affecting the way blood clots

When combined, these effects can raise the risk of a heart attack — especially if you already have high blood pressure, high cholesterol, or smoke cigarettes.

🗣️ What Experts Are Saying

Doctors are urging people — especially under 50 — to think twice before using marijuana regularly.

“Just because it’s legal doesn’t mean it’s safe,” says Dr. Andrew Freeman, a cardiologist not involved in the study. “People should treat cannabis like any other substance that can affect the heart.”

If you use weed, experts suggest talking to your doctor about your heart health, especially if you notice chest pain, dizziness, or shortness of breath.

💬 The Bottom Line

Cannabis might be legal in more places than ever, but that doesn’t mean it’s risk-free.
This new research is a wake-up call — especially for people who see marijuana as a “natural” or “safe” way to relax.

Heart health matters, and now it’s clear: weed could play a bigger role in heart attacks than anyone thought.
