People who are physically dependent to drugs or alcohol and want assistance will 1st go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is often uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required.
