What happens after you quit smoking? After 1 day: the risk of heart attack begins to decrease.
After 2 days: a person may notice a heightened sense of smell and more vivid tastes as their nerves heal.
After 1 month: in as little as one month, the person’s lung function begins to improve. As the lungs heal and get stronger, the capacity will improve. Former smokers may notice less coughing and shortness of breath, and snoring may even improve. After 1 year: after one year of quitting, a person’s risk of coronary heart disease is reduced by half.
