New Study Reveals Increased Risk of Heart Attack and Stroke for Young Marijuana Users
A recent study published in the Journal of the American College of Cardiology has found that individuals under the age of 50 who use marijuana are six times more likely to experience a heart attack and four times more likely to have a stroke compared to non-users. The study, which surveyed over 4.6 million people with no pre-existing cardiovascular conditions, suggests that marijuana use may have a significant impact on the cardiovascular system.
Researchers believe that marijuana may affect heart rhythm regulation, increase oxygen demand in the heart muscle, and make it harder for blood vessels to relax and expand, leading to interrupted blood flow. The study found that the risk of heart attack peaks about one hour after marijuana consumption, which is consistent with previous findings by the Centers for Disease Control and Prevention.
While the study does not specify how marijuana was consumed (smoking, vaping, or edibles), Dr. Robert Page, a professor of clinical pharmacy at CU Anschutz, notes that the correlation between marijuana use and increased risk of stroke and heart attack holds true regardless of the method of consumption. Page also emphasizes that the strength of the marijuana, as measured by THC levels, is directly linked to the increased risk of cardiovascular events.
The study’s findings are consistent with a smaller study by the American Heart Association last year, which found that cannabis use was associated with adverse cardiovascular outcomes. While more research is needed to fully understand the relationship between marijuana use and cardiovascular risk, the study’s results serve as a “red flag” and suggest that individuals who use marijuana regularly may be at increased risk for heart attack and stroke.
Dr. Page emphasizes that the data suggests that the longer and more frequently marijuana is used, the higher the risk of cardiovascular events. He also notes that individuals who use marijuana daily for five days or more may be at increased risk for stroke and heart attack.
Overall, the study highlights the need for further research into the effects of marijuana on the cardiovascular system and serves as a reminder that marijuana use may have unintended health consequences.
