Addiction is a condition in which the body must have a drug to avoid physical and psychological withdrawal symptoms. Addiction’s first stage is dependence, during which the search for a drug dominates an individual’s life. An addict eventually develops tolerance, which forces the person to consume larger and larger doses of the drug to get the same effect.
