Men and women who are physically reliant to drugs or alcohol and want help will 1st go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and provide medical supervision for persons who are just coming off of drugs.
