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. Detox is basically the procedure of the drug being eradicated 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 required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The individual 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 treatment facility which can present detox services, the client will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as quickly and safely as possible.
