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. Detox is basically the procedure of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and present medical supervision for individuals who are just coming off of drugs. Detox services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person 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 rehab facility which can provide detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as rapidly and safely as possible.
