Tobacco use

  • Smoking is estimated to cause nearly 10 per cent of all CVD.1 

  • The risk of developing CVD is higher in female smokers, young men, and heavy smokers.2

  • There are currently about 1 billion smokers in the world today.1

  • Within two years of quitting, the risk of coronary heart disease is substantially reduced, and within 15 years the risk of CVD returns to that of a non-smoker.3, 4
