Thanks for posting this. My uncle needs to see this to believe it. I found an article online that outlines what happens once someone quits.
The first day
Within 24 hours, the carbon monoxide – which hinders the blood from bringing oxygen to your cells, tissues and organs – has been removed from your body, and the mucus and smoking debris will start to clear from your lungs, making breathing easier.
First week
After two days there is no nicotine left in your body, and your senses of smell and taste will have started to improve dramatically. After three days, you should start to feel more energised and your breathing will become easier.
Three to five months
Within around three months your circulation will have improved, and any cough or wheezing should have mostly cleared up. Compared to when you were smoking, your lung function should have increased by around 10 per cent.
Five years
After several years, your risk of long-term disease begins to fall. After five years, the possibility of a heart attack is roughly half that of someone who is still smoking, and after ten years free from smoking, your heart attack risk is that of a non-smoker, while your risk of lung cancer has been halved.
