People who are physically dependent to drugs or alcohol and want assistance will initially 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 usually uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the particular person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detox services, the client will have detox staff at their disposal around the clock to assure that any complications are handled as swiftly and safely as possible.
