Quit Smoking Benefits - Two Weeks to Three Months

Quit smoking benefits include better lung function.

While the benefits of quitting smoking are just beginning, between two weeks and three months, major physical improvements have begun.

Between Two Weeks and Three Months:

  • Heart Attack Risk Begins to Drop and Circulation Improves
    Nicotine increases the level of adrenaline in a smoker's bloodstream, and this in turn elevates blood pressure by causing blood vessels to constrict and heart rate to increase. Smoking cessation alleviates this stress on the heart and circulatory system.
  • Lung Function Increases
    While improvements will vary greatly from one person to the next, and are dependent on overall lung health, ex-smokers may experience better lung function (defined as forced expiratory volume in one second) and less bronchial sensitivity.
  • Researchers also believe that smoking cessation stops the decline in lung function, including pathological and inflammatory changes that occur in the lungs due to tobacco smoke.
Physical Withdrawal from Nicotine is Subsiding

The worst of the physical symptoms of nicotine withdrawal begin to let go between two weeks and a month smoke-free. Following that, the focus shifts to learning how to decipher and reprogram the psychological urges to smoke that are associated with just about everything in our daily lives. From getting up in the morning, to eating a meal, to dealing with a difficult event or celebrating a happy one, the activities in our lives trigger psychological cues to smoke.

It is important to note that an urge to smoke originating in your mind can cause a physical reaction in your body, such as a tightening in the stomach or neck. It can be easy to misread these cues and think you are still in the midst of physical withdrawal weeks into cessation.

Pay attention to the thoughts running through your mind when the urge hits. They will help you diagnose the cause and from there you can choose an appropriate response. For instance, if you are feeling stressed, take a breather and go outside for some fresh air. Or, if you're hungry, have a snack. As smokers, we learned to respond to just about everything with a cigarette. As ex-smokers, we must learn to respond in healthier (and more accurate) ways.

Knowledge is Power

Education about what to expect when you stop smoking is a necessary part of a successful quit program. When you know what may be coming as you move through the process of recovery from nicotine addiction, you'll find yourself empowered and able to maneuver the bumps along the way without losing your balance.

Throw yourself into learning everything you can about nicotine addiction, and the process of quitting tobacco. It is a priceless investment in your future.
