Individuals who are physically dependent to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can effectively 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, providing proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as wanted to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to guarantee that any complications are resolved as swiftly and safely as possible.
