Substance use, abuse, and addiction

[Addiction+]

Substance use disorder is a cluster of physiological, behavioral, and cognitive symptoms associated with the continued use of substances despite substance-related problems, distress, and/or impairment, such as impaired control and risky use.

Addiction is a state of psychological and/or physical dependence on the use of drugs or other substances, such as alcohol, or on activities or behaviors, such as sex, exercise, and gambling.
