Cannabis has become quite prevalent in various settings, from pharmacies to social gatherings. Many people turn to it for improved sleep, relaxation, or pain relief, often viewing it as a natural alternative to traditional medications.
Yet, as cannabis use rises, heart specialists are observing concerning trends. A recent study published in the journal Heart, which analyzed data from over 432 million individuals, has found a troubling link.
Those who use cannabis face a significantly increased risk of heart attacks, strokes, and cardiovascular-related deaths. This isn’t mere speculation; it’s grounded in extensive research.
Rising Use of Potent Cannabis
In many U.S. states, as well as in some European countries like France, doctors can prescribe cannabis for medical purposes. However, recreational use remains illegal in those places. Despite this, many young individuals in France frequently use it. Meanwhile, Germany has recently changed its laws to permit recreational use starting in April 2024.
The demographic using cannabis is expanding, and the products have become more potent over the years, featuring higher levels of THC. This potency may lead to more intense effects on both the brain and heart.
Heart Issues Linked to Cannabis Use
The researchers examined 3,012 different studies, with 24 specifically focusing on cannabis and major cardiovascular events. Their analysis indicated that cannabis users have a 29% higher risk of heart attacks, 20% greater chance of strokes, and more than double the risk of dying from heart disease.
Increased Stroke Risk with Regular Use
The risk associated with strokes wasn’t uniform across all studies. A few showed weak correlations, especially in casual users. However, the risks were more apparent in habitual users and younger individuals.
For example, one study from Australia noted that weekly cannabis users were nearly five times more likely to experience a stroke or mini-stroke, with similar findings noted in a U.S. hospital database for those aged 25 to 34.
This suggests that occasional use might not pose serious risks, but regular consumption, particularly among youth, warrants caution.
Heart Attacks More Common Among Users
In younger adults aged 15 to 22, one study found a 36% greater likelihood of heart attacks among cannabis users. Another study revealed more than double the odds for those using it more than once a week, even after accounting for other substances like tobacco and cocaine. In fact, a French hospital study suggested that cannabis was the strongest predictor of heart issues, exceeding even cocaine.
This paints a different picture of cannabis than the one often touted, making the data quite compelling.
Increased Death Risk Related to Heart Disease
Researchers also explored fatal cardiovascular events. Findings showed that young patients who experienced heart attacks and used cannabis had a much higher mortality rate, even after accounting for smoking and other risk factors.
A separate U.S. study reiterated that cannabis users had an elevated risk of dying from heart-related issues. A surprising 2024 study in the UK indicated that women, rather than men, were at greater risk for heart-related fatalities stemming from heavy cannabis use.
Existing Benefits of Cannabis
While cannabis has notable medical benefits, especially when overseen by healthcare professionals, its risks shouldn’t be disregarded. It’s particularly recognized for helping manage chronic pain.
Individuals with conditions like arthritis or nerve injuries often find relief through cannabis treatment. The compounds in cannabis, primarily THC and CBD, can reduce pain signals and inflammation by interacting with the body’s endocannabinoid system.
Furthermore, medical cannabis has been beneficial for cancer patients who suffer from nausea due to chemotherapy, sometimes increasing their appetite when dealing with weight loss issues linked to illness.
Doctors have also utilized cannabis to assist patients with neurological disorders; for instance, CBD-based medications have been shown to decrease seizures in certain epilepsy cases, particularly among children.
These cases illustrate how, when used judiciously, cannabis can offer significant benefits, making it easy for some to overlook the associated health risks.
Calls for Tobacco-style Warnings
Experts, including Professor Stanton Glantz and Dr. Lynn Silver, emphasize the need to integrate cannabis into preventive measures for cardiovascular disease. They view it as crucial to also incorporate heart health considerations into cannabis market regulations.
They point out that contemporary cannabis differs greatly from its past forms, now consisting of high-concentration extracts and various edible products that may carry additional risks.
“We need clarity on how these changes might influence cardiovascular risks,” they stated, suggesting that cannabis should be regulated similarly to tobacco—acknowledged as a non-criminal substance but with discouragement closely tied to the need for protecting bystanders from secondhand exposure.
Healthcare providers should inquire about cannabis use, especially with patients who have heart issues. Perhaps it’s time to reconsider the perception that cannabis is without risk.
The study findings were published in the journal Heart.
