People who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can supply detox services, the client will have detoxification staff at their disposal around the clock to ensure that any problems are handled as quickly and safely as possible.
