The repetition of some socially unacceptable behavior, after that behavior had previously stopped (such as when a person successfully completes rehab and returns to substance abuse repeatedly) is called:

A. intoxication Intoxication refers to the acute effects of a substance on the body, not the repeated return to a behavior. B. dependence Dependence is a physical or psychological need for a substance, not the relapse after treatment. C. recidivism Recidivism refers to relapse-the recurrence of an undesirable behavior (like substance use) after a period of improvement. D. cross-tolerance Cross-tolerance occurs when tolerance to one drug results in tolerance to another, not repeated relapse.
