The term addiction usually refers to both psychological and physical dependence on a drug, including alcohol. Signs of dependence include withdrawal symptoms (such as depression, anxiety, irritability, cramps, nausea, sweating, and sleeping problems) when we stop using a substance. Another sign is being preoccupied with continuing to use the substance in spite of its negative effect. A third sign is tolerance - the need to use more and more to achieve the same effect.
