Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving 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 variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the individual will have detoxification staff at their disposal around the clock to assure that any problems are resolved as quickly and safely as possible.
