People who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detox services frequently include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as wanted to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
