People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before receiving 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 hold risks if not carried out in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and present medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the individual is as comfortable 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 necessary to make the detoxification process as easy and safe as possible. The individual 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 provide detox services, the client will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as quickly and safely as possible.
