Smoking and High Blood Pressure

Smoking can cause a build up of plaque in your blood vessels, which gives blood less room to get through, and raises blood pressure. You also take in carbon monoxide when you smoke, lowering the amounts of oxygen in your blood and organs.

When you smoke, it raises your blood pressure, temporarily, by as many as 20 points. And, on tops of all of this, smoking doubles the risk of heart attack, so come on, if you smoke, it's time to stop killing yourself.
