If you smoke, consider quittiing

For several minutes after you smoke a cigarette, your blood pressure will temporarily increase. If you smoke frequently, your blood pressure may remain high for a long time, and repeated temporary spikes in your blood pressure may cause damage.

Smoking increases the risk of heart attack, stroke, and dangerously high blood pressure. You can get high blood pressure and heart disease even from secondhand smoke. Furthermore, smoking can raise your chance of developing fatty substances inside your arteries known as plaque. Atherosclerosis is the name given to this condition. If untreated, it increases the risk of heart attack and stroke. Quitting smoking can help your blood pressure return to normal, in addition to a variety of other health benefits.
