Study Finds Recent Cannabis Use Associated With Lower Resting Heart Rate

Heart health is extremely important. For obvious reasons, if your heart isn’t healthy then it will affect the rest of your body. Heart failure is the leading cause of hospitalizations worldwide.

High blood pressure, high cholesterol, and smoking are the three leading contributors to heart disease. Chest pain and discomfort, shortness of breath, numbness, and abnormal heartbeats are all symptoms of poor heart health.

One way that heart health is measured is via a person’s resting heart rate. A lower resting heart rate indicates that the heart is using less effort to pump blood. A higher resting heart rate indicates that the heart is working hard to pump blood, even while the body is at rest, which is not good news.

A team of international researchers recently examined cannabis consumption’s impact, or lack thereof, on subjects’ resting heart rate. Below is more information about it via a news release from NORML:

San Francisco, CA: Current cannabis use is associated with lower resting heart rate, according to data published in The American Journal of Medicine.

A team of researchers from Switzerland and the United States assessed the relationship between cannabis exposure and heart rate in a cohort of middle-aged adults. Subjects in the study were participants in the Coronary Artery Risk Development in Young Adults (CARDIA) study – which is a multi-decade assessment of cardiovascular health. Previous findings from the CARDIA sample have failed to link the use of cannabis – even long-term – with an elevated risk of either atherosclerosishigh blood pressureECG abnormalities, or other serious cardiovascular events at middle age.

Researchers reported that subjects who occasionally consumed cannabis (defined as five times or more per month) possessed a lower resting heart rate than did non-users, including those who were former marijuana consumers.

“Current cannabis use was associated with lower resting heart rate, but cumulative cannabis exposure was not,” they reported. “Our findings align with epidemiological research on thousands of participants from Europe and the USA that found no association between cannabis and cardiovascular disease, mortality, or surrogate outcomes.”

Authors concluded: “Current cannabis use was associated with lower resting heart rate, which supports findings from experimental studies. … Past cumulative exposure to cannabis was not associated with heart rate, indicating the effects of cannabis exposure on heart rate are transient. Our findings add to the growing body of evidence suggesting a lack of deleterious association of cannabis use at a level typical of the general population on surrogate outcomes of cardiovascular disease.”
