American Heart Association Rapid Access Journal Report"},"content":{"rendered":"<p>AMERICAN HEART ASSOCIATION<\/p>\n<p>DALLAS, July 27, 2016 &#8212; Rats&#8217; blood vessels took at least three times longer to recover function after only a minute of breathing second-hand marijuana smoke, compared to recovery after a minute of breathing second-hand tobacco smoke, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association\/American Stroke Association.<br \/>&nbsp;<br \/>When rats inhaled second-hand marijuana smoke for one minute, their arteries carried blood less efficiently for at least 90 minutes, whereas similar exposure to second-hand tobacco smoke caused blood vessel impairment that recovered within 30 minutes.<br \/>&nbsp;<br \/>&#8220;While the effect is temporary for both cigarette and marijuana smoke, these temporary problems can turn into long-term problems if exposures occur often enough and may increase the chances of developing hardened and clogged arteries,&#8221; said Matthew Springer, Ph.D., study senior author and professor of medicine at the University of California, San Francisco&#8217;s Division of Cardiology.<br \/>&nbsp;<br \/>Blood vessel function was examined in rats before and after exposure to second-hand marijuana smoke at levels similar to real-world second-hand tobacco smoke.<br \/>&nbsp;<br \/>&#8220;Arteries of rats and humans are similar in how they respond to second-hand tobacco smoke, so the response of rat arteries to second-hand marijuana smoke is likely to reflect how human arteries might respond,&#8221;
