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