Circulation improves and cardiovascular fitness is greatly increased. Because of the benefits to the respiratory and circulatory systems, ex-smokers can participate in activities which they had to avoid while smoking. Ex-smokers are more productive, both at home and work, leaving them more time to do enjoyable recreational activities. Food smells and tastes better, making the ex-smoker much more capable of enjoying finer culinary treats. They become calmer, better able to deal with life's demands and stresses.
Aesthetic improvements are dramatic.
They smell better, and even the skin appears healthier. In many, not smoking will prevent premature wrinkling which would have occurred if they continued to indulge in cigarettes. They are more socially acceptable as ex-smokers. No longer do they have to worry about offending non-smokers around them. They can go anywhere, any time without worrying about whether they will be able to get their 20 minute fixes of nicotine.
