Smoking injures blood vessel walls and speeds up hardening of the
arteries (atherosclerosis). As a result, the heart works harder, and blood
pressure may increase. Cigarette smoking increases your risk for transient ischemic attack (TIA) and
Heavy smokers are at greater risk for TIA and stroke. Daily cigarette
smoking can increase the risk of stroke by 2½ times.1
The risk of stroke and TIA decreases for those who quit smoking. If
you smoked less than one pack a day and you quit, within 5 years your risk
will be the same as though you had never smoked.1
