Addiction: Addiction is a chronic, relapsing disorder characterized by compulsive drug-seeking and use, despite harmful consequences. It is a complex brain disease that involves changes in brain structure and function, leading to a loss of control and an inability to abstain from the addictive substance or behavior. Addiction can occur in the context of various substances, including opioids, nicotine, and other drugs of abuse, as well as certain behaviors, such as gambling or internet use. Addiction is a central concept in the understanding of substance use disorders, as described in the topics 14.3 Opioid Agonists and Antagonists, 15.1 Introduction to Substance Use Disorders, and 15.4 Nicotine Use Disorder Drugs. It is a critical factor in the development, maintenance, and treatment of these conditions.

Behavioral Therapy: Behavioral therapy is a type of psychotherapy that focuses on modifying an individual's behaviors and actions to improve their overall well-being. It is based on the principle that our thoughts, feelings, and behaviors are interconnected, and by changing our behaviors, we can positively impact our thoughts and emotions. In the context of 15.4 Nicotine Use Disorder Drugs, behavioral therapy is an important component of treatment for individuals struggling with nicotine addiction.
Bupropion: Bupropion is a medication primarily used for smoking cessation and to treat depression. It works by inhibiting the reuptake of norepinephrine and dopamine in the brain.
Chantix: Chantix, also known as varenicline, is a prescription medication used to help people quit smoking by reducing cravings and withdrawal symptoms. It works by blocking nicotine from binding to its receptors in the brain.
Children: Children are individuals in the developmental stage between infancy and adolescence. Their physiological and psychological characteristics impact how they respond to various pharmacological treatments.
