What is the percentage decrease in the likelihood of dying from tobacco-related diseases if a client quits before the age of 40?

The likelihood of dying from tobacco-related diseases significantly decreases when individuals quit smoking before the age of 40. Research indicates that if a person ceases smoking at this age, their risk of mortality from diseases associated with tobacco can drop by approximately 90%. This substantial reduction is because quitting smoking at a younger age allows the body to begin repairing damage caused by tobacco use, leading to long-term health benefits and a considerable decrease in the risk of developing serious health issues later in life, such as heart disease, cancer, and respiratory illnesses.

The percentage figures provided in the other answer choices reflect varying levels of risk reduction, but only the 90% figure accurately captures the robust evidence linking early cessation of tobacco use to dramatically lower mortality rates associated with smoking. This underscores the critical importance of early intervention and smoking cessation efforts in public health initiatives aimed at reducing tobacco-related diseases.
