Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is frequently uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can correctly oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as required 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 detox facility or drug treatment facility which can present detox services, the client will have detox staff at their disposal around the clock to make certain that any problems are resolved as rapidly and safely as possible.
