Smoking is a major cause of several diseases. The Centre for Disease Control (CDC) states that it causes cancer, heart disease, stroke, lung diseases, including emphysema, bronchitis and chronic airway obstruction and diabetes. Smoking takes nearly 443,000 lives every year and it also affects second hand smokers who are only exposed to the smoke and are not indulging in the act.

Majority of the smokers are aware of the problems that come with the habit, but continue to smoke. A few however, try to come out of the habit and begin a healthy lifestyle. There are several celebrities who have successfully adopted a healthier lifestyle and quit smoking. They are an inspiration to those who want to get rid of this habit.

According to the American Heart Association (AHA), it is difficult to quit smoking. It states that nicotine addiction is hard to come out because it elevates the mood and the heart rate. The carving for cigarette increases once the body gets used to it. The surgeon general's study on nicotine concluded that "behavioral characteristics that determine tobacco addiction are similar to those that determine addiction to drugs such as heroin and cocaine".

The AHA also stated that most people take cigarettes when they are stressed, so it would be hard to handle stress when they quit, hence they go back to the habit time and again to handle their emotions. Keeping this in mind it would be best to know the ways in which these celebrities kicked the habit of smoking.

Cameron Diaz used to smoke 20 cigarettes a day but is extremely health conscious now and has said goodbye to her old habit. She said that her conscience and the feeling of guilt compelled her to quit. Jennifer Aniston took the yoga route to say farewell to her habit.

Several celebrities took cigarettes to stay thin and Gisele Bundchen was one of them. Smoking reduces ones appetite and it helped her stay in shape. She became a role model to several young women when she quit her habit in 2003. Bundchen stated that she put on 15 pounds after quitting and her new lifestyle and healthy body gave her a lot of joy.

Apart from this, some celebrities went to the rehab and some took to the Kerry Gaynor Method, a program developed by the well-known hypnotherapist Kerry Gaynor. Irrespective of the ways in which they quit, each of these celebrities are a role model to several people who want a healthier lifestyle and their lifestyle proves that though quitting the habit is hard, it is not impossible.
