Everyone knows smoking is bad for your lungs, but you may not realize tobacco is responsible for 1 in 10 heart disease deaths.
Thursday was World Tobacco Day, and the World Health Organization released a video explaining how cigarettes take a toll on your heart. In addition to warning viewers about the number of heart disease deaths caused by smoking, the video also notes that second-hand smoke can put you at risk of heart attack and stroke.
To illustrate the effects of smoking, the 30-second clip shows a heart transforming from smooth to damaged and full of ripples.
