Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and present medical supervision for people who are just coming off of drugs. Detox services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as smooth 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 provide detox services, the person will have detox staff at their disposal around the clock to assure that any difficulties are handled as quickly and safely as possible.
