When quitting smoking at 30 years of age, how many years of life might be gained?

Quitting smoking at 30 years of age can significantly impact life expectancy. Research indicates that individuals who quit smoking before the age of 40 can gain substantial years of life compared to those who continue smoking. Specifically, studies suggest that quitting at around 30 years of age might help an individual gain approximately 10 years of life, as they avoid the increased health risks associated with prolonged tobacco use, including heart disease, cancer, and respiratory illnesses. This gain in years is a testament to the body’s remarkable ability to recover from the harmful effects of smoking, especially when the harmful habit is discontinued early in adulthood.
