Exposure to Secondhand Marijuana Smoke
Early research shows that breathing in secondhand smoke from marijuana has similar effects on the cardiovascular system (i.e., heart arteries, veins and blood) as inhaling secondhand smoke from tobacco products, such as cigarettes. A recent study1 showed inhalation of secondhand marijuana smoke makes it harder for arteries to expand, decreasing blood flow throughout the body.
