Despite the growing perception among many Americans that marijuana is safe, recent research published this week in the journal Heart reveals concerning associations between marijuana use and serious health risks, including a higher likelihood of stroke and heart attack. This comprehensive analysis reviewed data from 24 studies and highlighted a troubling correlation: individuals who use marijuana may face a twofold increase in the risk of death from cardiovascular disease.
While the findings indicate a correlation rather than a direct cause-and-effect relationship, it is important to note that marijuana is known to elevate blood pressure and heart rate, as well as disrupt the heart's rhythm. Dr. Ersilia DeFilippis, a cardiologist at Columbia University Irving Medical Center, emphasizes that these physiological changes can significantly stress the heart. Numerous studies have also suggested connections between marijuana and various cardiovascular issues, underscoring the potential dangers associated with its use.
This analysis arrives at a pivotal moment when nearly half of U.S. states have legalized marijuana for recreational use. In fact, a record 15 percent of U.S. adults reported using marijuana in 2022. Emilie Jouanjus, the senior author of the study and a pharmacologist at the University of Toulouse in France, acknowledges that while there may be valid reasons for using marijuana—such as alleviating stress and anxiety—patients should not assume it is entirely harmless. She, along with other experts, urges caution and suggests several strategies for individuals to mitigate their health risks associated with marijuana use.
Health experts indicate that certain populations are more vulnerable to the negative effects of marijuana. Generally, older adults and those with underlying health conditions—such as diabetes, high cholesterol, or pre-existing heart issues—are at heightened risk. Their cardiovascular systems are often more fragile, and the additional stress from marijuana can exacerbate these conditions. Interestingly, in 2023, approximately 7 percent of U.S. adults aged 65 and older reported using marijuana in the past month. However, the average age of participants in the new analysis was just 38, indicating that younger individuals are also facing increased risks from marijuana use.
As marijuana continues to gain popularity across the United States, it is crucial for users, especially those at higher risk, to be aware of the potential health implications associated with its use. The recent findings serve as a vital reminder to approach marijuana with caution and to consult healthcare professionals regarding its effects on heart health and overall well-being.
