Unit 4 Tobacco, Alcohol, and Other Drugs Copyright Goodheart-Willcox Co., Inc. 294 Addiction Addiction develops when a person continues using a substance despite negative effects on health. Addiction is the physical and psychological need for a given substance or behavior. For example, people may continue smoking or vaping, even if they experience social isolation or have to turn to other measures to afford the substance. At this point, a person has developed a substance use disorder. Withdrawal Symptoms Withdrawal occurs when someone with an addiction to a substance tries to stop using that substance. The term withdrawal describes unpleasant symptoms. These symptoms vary based on the addictive substance. People with an addiction to nicotine may experience irritability, difficulty concentrating, fatigue, nausea, and weight gain during withdrawal. They also experience intense cravings for nicotine. This occurs because the body is physically dependent on this substance. Withdrawal is one of the reasons people who use tobacco have such difficulty quitting. The withdrawal symptoms for tobacco last several weeks or even months. Some people who quit tobacco use have occasional tobacco cravings for years after quitting. Lesson 9.2 Review 1.
