What happens when you give up cigarettes? A Quit Smoking Timeline

It’s common for smokers to feel that their future without cigarette is bleak: that it’s impossible to enjoy a meal without a cigarette before, or after, or both; that there is no way in which they could achieve what they have achieved without all of those smoke breaks. It’s hard not to imagine a sense of loss.

To imagine your smoke-free future as it really is — a positive one — it might be worth having a look at the quit smoking timeline: what changes you can reliably expect for your health as you live smoke-free.

After 20 minutes

The benefits start very early. In only twenty minutes, your blood pressure will return to normal levels. Additionally, the ciliated epithelial cells — the cells that line the lungs, wafting mucus and irritants along its passageways — will begin to work better, reducing the risk of infection and congestion.

After 8 hours

There will be half the amount of carbon monoxide (CO) in your body as there would have been as a smoker. CO — absorbed due to the incomplete combustion of involved in lighting up — causes oxygen (O2 levels in your blood to decrease. This is because haemoglobin (the stuff in red blood cells that binds to oxygen) has a greater affinity with CO than O2, meaning that when it enters, O2 absorption rates decrease. This lowers the level at which all organs in the body (including the brain!) can function at. But due to this fall in CO in the bloodstream, your body will work be working better—after just a third of a day.

After 2 days

Your risk of a heart attack will have decreased. This is because harmful stimulant effects of nicotine are wearing off: the musculature around your blood vessels get artificially raised as you smoke, raising your blood pressure and making your heart have to work unnecessarily harder.

After 3-9 months

Any coughing, wheezing and/or wheezing complaints will have begun to subside due to the fact that lung capacity will increase as much as 10%. This will make enjoyable activities like walking even more enjoyable, and mundane activities like climbing stairs easier.

After 1 year

The benefits of being smoke-free for your circulation system will have compounded substantially, dividing your chance of a coronary neatly in two.

After 10 years

In a decade’s time, your risk of death from lung cancer will have halved compared to the risk that a smoker is at. You are no longer sustaining that to your lungs, meaning that there is far, far less chance of having one of those damaged cells repairing and then mutating into something like a carcinoma.

There we have it: the trajectory in which, with the right support, you are headed. This is of course a reductive overview: it does not account for the social and psychological benefits that not smoking will certainly bring. It also doesn’t account for reduced risk of complaints like stomach ulcers or rheumatoid arthritis: other diseases linked with smoking. With these facts in mind, you can begin to see that all those sustained moments of not-smoking are overseeing a huge improvement, bodily and otherwise.
