People who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure 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 needed. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detox 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 rehabilitation facility which can present detox services, the individual will have detox staff at their disposal around the clock to ensure that any problems are handled as rapidly and safely as possible.
