Researchers from the United States and Switzerland explored the association between cannabis exposure and heart rate in a large cohort of middle-aged adults.
The team of scientists determined that cumulative exposure to cannabis use was not associated with heart rate. Even more, the study found that subjects who occasionally consumed marijuana, which they defined as at least five times per month, exhibited a lower resting heart rate than those who were non-users.
“Current cannabis use was associated with lower resting heart rate, but cumulative cannabis exposure was not,” the study said. “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.”
