People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification 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. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can properly oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to assure that any complications are fixed as quickly and safely as possible.
