Addiction is a compulsion to repeat a behaviour regardless of its consequences.
A person who is addicted is sometimes called an addict.
Addiction is often characterized by a craving for more of the drug or behavior, increased physiological tolerance to exposure, and withdrawal symptoms in the absence of the stimulus.
Many drugs and behaviours that provide either pleasure or relief from pain pose a risk of addiction or dependency.
