A good chart to all those just starting on their quits. I used this as my motivator during my quit:
20 minutes
Your blood pressure, pulse rate and the temperature of your hands and feet have returned to normal.
8 hours
Remaining nicotine in your bloodstream has fallen to 6.25% of normal peak daily levels, a 93.75% reduction.
12 hours
Your blood oxygen level has increased to normal. Carbon monoxide levels have dropped to normal.
24 hours
Anxieties have peaked in intensity and within two weeks should return to near pre-cessation levels.
48 hours
Damaged nerve endings have started to regrow and your sense of smell and taste are beginning to return to normal. Cessation anger and irritability will have peaked.
72 hours
Your entire body will test 100% nicotine-free. Over 90% of all nicotine metabolites (the chemicals nicotine breaks down into) have passed from your body via your urine. Symptoms of chemical withdrawal have peaked in intensity, including restlessness. Unless use cues have been avoided, the number of cue induced crave episodes experienced during any quitting day have peaked for the "average" ex-user. Lung bronchial tubes leading to air sacs (alveoli) are beginning to relax in recovering smokers. Breathing is becoming easier and your lung's functional abilities are improving.
5 - 8 days
The "average" ex-smoker is down to experiencing just three cue induced crave episodes per day. Although we may not be "average" and although minutes may feel like hours when normal cessation time distortion combines with the body's panic response, it is unlikely that any single episode will last longer than 3 minutes. Keep a clock handy and time the episode to maintain an honest perspective on time.
10 days
The "average" ex-user is down to encountering less than two crave episodes per day.
10 days to 2 weeks
Recovery has likely progressed to the point where your addiction is no longer doing the talking. Blood circulation in your gums and teeth are now similar to that of a non-smoker.
2 to 4 weeks
Cessation related anger, anxiety, difficulty concentrating, impatience, insomnia, restlessness and depression have ended. If still experiencing any of these symptoms get seen and evaluated by your physician.
2 weeks to 3 months
Your heart attack risk has started to drop. Your lung function has noticeably improved. If your health permits, sample your circulation and lung improvement by walking briskly, climbing stairs or running further or faster than normal.
21 days
The number of acetylcholine receptors, which were up-regulated in response to nicotine's presence in the frontal, parietal, temporal, occipital, basal ganglia, thalamus, brain stem and cerebellum regions of your brain have now substantially down-regulated. Receptor binding has returned to levels seen in the brains of non-smokers (2007 study).
3 weeks to 3 months
Your circulation has substantially improved. Walking has become easier. Your chronic cough, if any, has likely disappeared. If not, get seen by a doctor, and sooner if at all concerned, as a chronic cough can be a sign of lung cancer.
4 weeks
Plasma suPAR is a stable inflammatory biomarker that helps predict development of diseases ranging from diabetes to cancer in smokers. A 2016 study found that within 4 weeks of quitting smoking, with or without NRT, that suPAR levels in 48 former smokers had fallen from a baseline smoking median of 3.2 ng/ml to levels "no longer significantly different from the never smokers' values" (1.9 ng/ml)
8 weeks
Insulin resistance in smokers has normalized despite average weight gain of 2.7 kg.
1 to 9 months
Any smoking related sinus congestion, fatigue or shortness of breath has decreased. Cilia have regrown in your trachea (windpipe) thereby increasing the ability to sweep dirt and mucus out of your lungs. Your body's overall energy has increased.
11 months
Smoking decreases the thickness of the brain's outer layer, the cortex. Smoking induced cortical thinning is associated with poor decision making, risk taking, a lack of impluse control, early dementia, and nearly 14% of Alzheimer’s cases worldwide. According to a 2015 study, it takes 0.9 years (10.8 months) without smoking to recover from the cortical thinning effect of each pack-year of smoking. Congratulations, your cortex is growing thicker and the quality of your thoughts, decisions and actions has improved.
1 year
Your excess risk of coronary heart disease, heart attack and stroke has dropped to less than half that of a smoker.
