Question: 1 / 400

What is the relative risk of stroke in smokers compared to non-smokers?

Normal risk

2-5 times higher

The relative risk of stroke in smokers compared to non-smokers is indeed significantly higher, with research indicating that smokers have a 2 to 5 times higher risk of experiencing a stroke. This increased risk is attributed to various factors related to smoking, such as the damage caused to blood vessels, increased blood pressure, and the promotion of plaque buildup in the arteries, which can all lead to vascular issues and stroke.

Nicotine and other harmful chemicals present in tobacco can cause chronic inflammation and damage endothelial cells, impacting blood flow and increasing the likelihood of clot formation. The cumulative effects over time contribute to the elevated incidence of both ischemic and hemorrhagic strokes among smokers.

Understanding this risk is crucial for public health, as it underscores the importance of smoking cessation programs and initiatives aimed at reducing tobacco use, thereby potentially lowering the incidence of stroke in the population.
