People who are physically reliant to drugs or alcohol and want assistance will first 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 frequently uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and present medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as required to make the detox process as easy 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 detox facility or drug treatment facility which can provide detoxification services, the individual will have detoxification staff at their disposal around the clock to assure that any complications are fixed as rapidly and safely as possible.
