Drug tolerance is a state of decreased sensitivity to a drug as a result of previous exposure to the drug. This means that higher doses of the drug are needed to achieve the same effects as before.

Drug withdrawal, physical dependence, and psychological dependence are related concepts but refer to different aspects of drug use and abuse.
