What is the difference between physical and psychological addiction?

Physical addiction occurs when your body becomes dependent on a substance and experiences withdrawal symptoms when you stop using it. These symptoms can include shaking, sweating, nausea, and in severe cases, seizures. Psychological addiction involves the emotional and mental dependence on a substance or behavior. You might crave it to cope with stress, feel normal, or experience pleasure. Many addictions involve both physical and psychological components. Understanding this difference is important because recovery needs to address both aspects - medical support for physical withdrawal and therapy for psychological dependence.
