Smoking cessation (colloquially quitting smoking) is the process of discontinuing tobacco smoking. Tobacco contains nicotine, which is addictive.[1]
Smoking cessation can be achieved with or without assistance from healthcare professionals, or the use of medications. However, a combination of personal efforts and medications proves more effective to many smokers.[2] Methods that have been found to be effective include interventions directed at or via health care providers and health care systems; medications including nicotine replacement therapy (NRT) and varenicline; individual and group counselling. Although stopping smoking can cause short-term side effects such as reversible weight gain, smoking cessation services and activities are cost-effective because of the positive health benefits.
