How to Use the Quit Smoking Recovery Simulator
Enter how many years you smoked and how many cigarettes you smoked per day. The simulator calculates your pack-year total and risk level, then displays a personalized body recovery timeline from 20 minutes to 15 years after quitting.
A pack-year equals one pack (20 cigarettes) per day for one year. For example, smoking 10 cigarettes a day for 10 years equals 5 pack-years. Under 10 is mild risk, 10–20 is moderate, and 20+ is high risk. Higher pack-years suggest longer lung recovery, but cardiovascular benefits begin quickly for everyone.
The timeline is based on research from the WHO and CDC and represents general health improvements. Individual results vary depending on health conditions and lifestyle. This tool is for informational purposes only and does not replace medical advice.
