People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and present medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is getting proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to ensure that any problems are fixed as quickly and safely as possible.
