成瘾（英语：Addiction）是指一种重复性的强迫行为，即使这些行为已知可能造成不良后果的情形下，仍然被持续重复。这种行为可能因中枢神经系统功能失调造成，重复这些行为也可以反过来造成神经功能受损。

Addiction is a medical condition that is characterized by compulsive engagement in rewarding stimuli, despite adverse consequences. It can be thought of as a disease or biological process leading to such behaviors. The two properties that characterize all addictive stimuli are that they are reinforcing (i.e., they increase the likelihood that a person will seek repeated exposure to them) and intrinsically rewarding (i.e., something perceived as being positive or desirable).
