What Is Drug Addiction?
Drug addiction, also known as substance use disorder, is a chronic and often relapsing condition characterised by the compulsive use of drugs despite the negative consequences it causes. It is a brain disease that affects a person’s behaviour, motivation, and decision-making abilities.
Addiction can occur with various substances such as alcohol, opioids, cocaine, marijuana, and prescription drugs. When a person becomes addicted, they may experience intense cravings for the drug and require increasing amounts to achieve the same effects. They may also experience withdrawal symptoms when they stop using the drug.
