Men and women who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated 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 required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and present medical supervision for people 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, providing proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as wanted to make the detoxification process as smooth 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 rehab facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any problems are resolved as quickly and safely as possible.
