People who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is receiving proper rest, and supplying 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 sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the client will have detox staff at their disposal around the clock to make certain that any issues are handled as swiftly and safely as possible.
