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