Individuals who are physically reliant to drugs or alcohol and want assistance will 1st go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can provide detoxification services, the client will have detoxification staff at their disposal around the clock to assure that any complications are resolved as quickly and safely as possible.
