Individuals who are physically reliant to drugs or alcohol and want help will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as easy and safe as possible. The individual 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 supply detox services, the client will have detoxification staff at their disposal around the clock to assure that any complications are fixed as swiftly and safely as possible.
