In 8 hours…
Remaining nicotine in your bloodstream has fallen to 6.25% of normal peak daily levels, a 93.75% reduction.

In 12 hours when you stop smoking …
Your blood oxygen level has increased to normal. Carbon monoxide levels have dropped to normal.

In 24 hours…
Anxieties have peaked in intensity and within two weeks should return to near pre-cessation levels.

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.

In 72 hours…
Your entire body will test 100% nicotine-free and over 90% of all nicotine metabolites (the chemicals it breaks down into) will now have passed from your body via your urine.

In 5 – 8 days…
The “average” ex-smoker will encounter an “average” of three cue induced crave episodes per day.

In 10 days after you stop smoking …
10 days – The “average” ex-user is down to encountering less than two crave episodes per day, each less than 3 minutes.

In 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-user.

In 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.

In 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 the brain, have now substantially down-regulated, and receptor binding has returned to levels seen in the brains of non-smokers.

In 2 weeks to 3 months…
Your heart attack risk has started to drop. Your lung function is beginning to improve.

In 3 weeks to 3 months…

In 4 weeks after you stop smoking …
Plasma suPAR is a stable inflamatory biomarker predictive of 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)

In 8 weeks…
Insulin resistance in smokers has normalized despite average weight gain of 2.7 kg.

In 1 to 9 months…
Any smoking related sinus congestion, fatigue or shortness of breath has decreased. Cilia have regrown in your lungs, thereby increasing their ability to handle mucus, keep your lungs clean and reduce infections. Your body’s overall energy has increased.

In 1 year…
Your excess risk of coronary heart disease, heart attack and stroke has dropped to less than half that of a smoker.

In 5 years…

In 5 to 15 years…
Your risk of stroke has declined to that of a non-smoker.

In 10 years…
Your risk of being diagnosed with lung cancer is between 30% and 50% of that for a continuing smoker. Risk of death from lung cancer has declined by almost half if you were an average smoker (one pack per day). Risk of cancer of the mouth, throat, esophagus and pancreas have declined. Risk of developing diabetes for both men and women is now similar to that of a never-smoker.

In 13 years…
The average smoker who is able to live to age 75 has 5.8 fewer teeth than a non-smoker. But by year 13 after quitting, your risk of smoking induced tooth loss has declined to that of a never-smoker.
