In recent weeks, headlines have raised alarm:

“Weed use linked to heart-related deaths,”
“Is marijuana as bad for your heart as cigarettes?”

These reports have understandably caused concern—especially among older adults considering cannabis for health reasons.

At Healer, we believe in replacing fear with facts. So let’s break down the research behind the headlines, with guidance from integrative medicine expert Dr. Dustin Sulak.

The Study That Sparked the Storm: Cannabis & Cardiovascular Risk

The source of the recent media frenzy? A 2025 systematic review and meta-analysis published by French researchers. It evaluated 24 observational studies (2016–2023) on cannabis and cardiovascular risk.

The conclusion:
Cannabis users had more than double the risk of cardiovascular death compared to non-users.

But the deeper truth? It’s far more nuanced—and far less alarming.

Why the Data on Marijuana & Heart Disease Is Flawed

While the authors were transparent, the review has serious limitations:

• None of the 24 studies were rated as low risk of bias
• Most were high risk, and only four fell into the “some concerns” category
• The striking cardiovascular risk statistic came from just three studies
  • Two showed significant risk
  • One showed no difference

Bottom line: Poor-quality studies lead to poor-quality conclusions.

A Closer Look: Marijuana and Heart Attack Risk by Age

One of the key studies in the review, conducted by Reese et al. (2017), analyzed over a million hospital records and revealed surprising age-specific differences:

• Younger users had a higher incidence of heart attack
• Middle-aged users showed no increased risk
• Older users (60+) had lower heart attack rates than non-users

Other noteworthy findings:

• Cannabis users were less likely to die from heart attacks
• They had fewer complications and less need for invasive procedures
• They did require more ventilator support—possibly due to smoking-related lung issues

These details were left out of most news coverage.

Cannabis and Heart Health Headlines: Correlation ≠ Causation

This review revealed associations, not cause and effect.

Key considerations:

• Many cannabis users also use tobacco, alcohol, or other substances
• Lifestyle factors weren’t controlled for
• In some studies, participants were considered “cannabis users” after only one use

That’s not science—it’s noise.

Is Cannabis Worse Than Cocaine? Separating Fact from Fiction

One headline claimed cannabis may pose greater heart risk than cocaine.

Here’s the truth:

• The claim came from one paragraph in one study
• The authors themselves said it was likely skewed by:
  • Low rates of reported cocaine use
  • Unreliable self-reporting of illegal drug use

There’s no strong evidence to support that comparison.

Emerging Research: Can Cannabinoids Protect the Heart?

Here’s what the media isn’t telling you: cannabinoids may actually protect the cardiovascular system.

Promising findings include:

• Animal studies: Low-dose THC activates CB2 receptors, reducing vascular inflammation and slowing atherosclerosis
• Clinical research: Cannabis users may have better outcomes after strokes or brain injuries
• One study found:
  • 19% of cannabis users had no lingering symptoms after a brain hemorrhage
  • Compared to only 3% of non-users

The Real Cardiovascular Risks—and How to Reduce Them

Dr. Sulak is clear: cannabis can affect the cardiovascular system.

Inhaling high-THC cannabis can temporarily:

• Lower blood pressure
• Increase heart rate

For most people, this is like walking up a flight or two of stairs—not dangerous, but not ideal for those with angina or advanced cardiovascular disease.

Dr. Sulak recommends:

• Avoid inhalation—opt for other routes of administration
• Start low and go slow with appropriately dosed edibles
• Use non-psychoactive cannabinoids like CBDa or CBG for anti-inflammatory benefits without cardiovascular strain

Final Thoughts: Cannabis Heart Risk vs. Therapeutic Benefit

Every medication carries some risk. But when used correctly, cannabis offers powerful, proven benefits:

• Reduced reliance on opioids, sedatives, antidepressants, and NSAIDs
• Improved quality of life for chronic pain, anxiety, sleep, and more

Sadly, much of the media coverage omits this context—potentially discouraging those who could benefit most.
