Tobacco Use Disorder

About Tobacco Use Disorder

Tobacco use disorder is a problematic pattern of tobacco use, usually involving dependence on nicotine, leading to significant impairment or distress. Features include using more than intended, persistent desire or unsuccessful efforts to cut down or quit, craving, continued use despite knowing it causes or worsens health problems, and tolerance and withdrawal. Nicotine withdrawal can include irritability, anxiety, difficulty concentrating, increased appetite, restlessness and low mood. Tobacco use is a leading preventable cause of death worldwide, linked to cancer, heart disease, stroke and lung disease, and it is especially common among people with other mental health conditions. Many people make several attempts before quitting successfully, and relapse is common. The most effective approach combines behavioral support, such as counseling or quitline services, with medications such as nicotine replacement therapy, varenicline or bupropion, which together substantially increase the chance of quitting compared with willpower alone.
