Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can supply detoxification services, the client will have detoxification staff at their disposal around the clock to guarantee that any complications are fixed as swiftly and safely as possible.
