Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The particular person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to assure that any problems are resolved as quickly and safely as possible.
