People who are physically reliant to drugs or alcohol and want assistance will first 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 hold risks if not carried out in a setting which can offer appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and supply medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the client will have detoxification staff at their disposal around the clock to ensure that any issues are resolved as swiftly and safely as possible.
