Addiction is a complex condition characterised by an overwhelming need to use a substance or engage in a behaviour despite harmful consequences. It often begins with voluntary use or activity but can develop into a chronic disorder involving brain changes that impact self-control, decision-making, and behaviour. Addiction can affect anyone, regardless of age, background, or social status, and may involve substances such as alcohol, drugs, or behaviours like gambling or gaming. Recognising the signs early and seeking professional help can lead to effective management and recovery.
