People who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to make certain that any problems are resolved as rapidly and safely as possible.
