Smoking is very bad for your heart. It greatly increases the risk of a heart attack, other types of heart disease and stroke.
The good news is that once you stop smoking, the extra risk is reduced quickly.
Smoking affects the vessels that supply blood to your heart and other parts of your body. It reduces the amount of oxygen in your blood and damages blood vessel walls.
Breathing in other people's smoke can also increase your risk of heart disease.
You can get lots of help to quit. Talk to your doctor or health practitioner about giving up smoking.
