According to new information published in the journal Addiction, marijuana use over time is not independently associated with an increased risk of atherosclerosis, or hardened arteries. A team of researchers from the United States and Switzerland looked at the use of tobacco and/or cannabis in association with atherosclerosis in a group of 3,117 subjects between ages 18 and 30. Those who had never smoked tobacco, but had used marijuana, were “were not associated with AAC (abdominal artery calcium) or CAC (coronary artery calcium).” On the other end of the spectrum, those who had smoked tobacco but not marijuana, or had used both substances, for over five years were at an increased risk of subclinical atherosclerosis. This supports previous finding that suggest marijuana use over a span of time does not increase risk for cardiovascular disease, stroke, or coronary heart disease.
