Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services often 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 receiving proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehabilitation facility which can present detox services, the person will have detoxification staff at their disposal around the clock to guarantee that any complications are handled as rapidly and safely as possible.
