You've decided to stop smoking, but you're wondering whether quitting suddenly can be harmful? The first thing to say is that quitting all at once poses no health risk. As to whether quitting gradually (i.e., continuing to consume a few cigarettes a day and gradually cutting down) proves more difficult, it would appear to be the case. In one study, the success rate was higher among smokers who chose to quit cold turkey. However, each person has his or her own method of quitting smoking, with the ultimate goal being total cessation. In any case, quitting smoking cold turkey does not mean quitting unprepared. Rationalizing your project and putting a strategy in place will increase your chances of success.
