People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may carry risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can properly oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to assure that any issues are fixed as quickly and safely as possible.
