For many people, detox is the first real step toward breaking free from substance use. It is the stage where the body begins adjusting after drugs or alcohol are removed. That adjustment can be uncomfortable and sometimes unpredictable because the brain and nervous system have grown used to the substance.
NIH guidance describes detoxification as a short-term medical process focused on safely managing withdrawal and stabilizing the patient, while also connecting them to ongoing addiction treatment rather than viewing detox as a stand‑alone cure.
