Smoking and stroke

Smoking and stroke: Smoking can increase your risk of stroke or further stroke by increasing blood pressure and reducing oxygen in the blood.

Nicotine is the chemical that makes smoking addictive. Tobacco smoke contains over 4,000 toxic chemicals which are deposited on the lungs or absorbed into the bloodstream.

Some of these chemicals damage blood vessel walls, leading to atherosclerosis (narrowing and hardening of the arteries). This increases the chance of blood clots forming in the arteries to the brain and heart.

Smoking also increases the stickiness of the blood. This further increases the risk of blood clots forming.

Seek advice on how you can quit smoking as soon as possible by calling the QUIT line on 13 18 48.
