Nicotine withdrawal is a group of symptoms that occur in the first few weeks after stopping or decreasing use of nicotine. Symptoms include intense cravings for nicotine, anger or irritability, anxiety, depression, impatience, trouble sleeping, restlessness, hunger, weight gain, and difficulty concentrating. Withdrawal symptoms make it harder to quit nicotine products, and many smoking cessation methods aim to reduce these symptoms. Smoking cessation programs can help increase the chances of success. Nicotine withdrawal is recognized in both the American Psychiatric Association Diagnostic and Statistical Manual (DSM) and the WHO International Classification of Diseases (ICD).

Nicotine withdrawal in the context of Smoking cessation
Smoking cessation, usually called quitting smoking or stopping smoking, is the process of discontinuing tobacco smoking. Tobacco smoke contains nicotine, which is addictive and can cause dependence. As a result, nicotine withdrawal often makes the process of quitting difficult.
Smoking is the leading cause of preventable death and a global public health concern. Tobacco use leads most commonly to diseases affecting the heart and lungs, with smoking being a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), emphysema, and various types and subtypes of cancers (particularly lung cancer, cancers of the oropharynx, larynx, and mouth, esophageal and pancreatic cancer). Smoking cessation significantly reduces the risk of dying from smoking-related diseases. The risk of heart attack in a smoker decreases by 50% after one year of cessation. Similarly, the risk of lung cancer decreases by 50% in 10 years of cessation
