Discussion

Cohort study reveals smoking significantly increases death risk in adults, while cessation effects vary by age.

Smoking increases all-cause death risk by 2.4 times, escalating to 3.5 times for ages 20-39, emphasizing its dangers.
The cohort of 1546 individuals exhibited 556 deaths, with 244 attributed to cardiovascular diseases (CVD), during follow-up.
Analysis confirmed quitting smoking does not reduce death risk for older adults, yet younger quitters face reduced risks.
Thirty-four-year survival rates show non-smokers at 70.2%, smokers at 47.2%, and quitters at 57.1%, highlighting cessation's benefits.
