People who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is frequently uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and provide medical supervision for people 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 particular person is receiving proper rest, and supplying supplements and medicine as required to make the detoxification process as easy and safe as possible. The particular person in detox 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 treatment facility which can provide detox services, the person will have detox staff at their disposal around the clock to ensure that any problems are resolved as rapidly and safely as possible.
