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. Detox is simply the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detoxification 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 provide detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any issues are fixed as swiftly and safely as possible.
