Final answer:
An addictive drug is a substance that leads to physiological or psychological dependence, resulting in a compulsion to use the drug despite adverse effects. Dependence may manifest as withdrawal symptoms upon cessation, and rehabilitation often involves various forms of psychotherapy.
Step-by-step explanation:
A substance that causes physiological or psychological dependence is called an addictive drug. Sustained use of an addictive drug may lead to the development of dependence, which can be physical, psychological, or both. This phenomenon occurs when the body or mind adapts to the presence of the drug, and its absence leads to withdrawal symptoms. Physical dependence results in physical withdrawal symptoms like tremors and pain, while psychological dependence leads to symptoms such as anxiety and depression.
Drug addiction refers to the compulsive use of a substance despite the negative consequences that such use may entail. Rehabilitation typically involves psychotherapy and may sometimes use other psychoactive substances that help reduce cravings without creating addiction themselves.
The misuse of psychoactive drugs, which alter mood and behavior, can lead to addiction. Addiction involves a craving for the drug and a persistent use of it despite harmful consequences. Rehabilitation for addiction includes supportive therapy and may involve mutual aid fellowships such as AA and NA.
