Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting 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 conducted in a setting which can provide appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can properly oversee and provide medical supervision for persons who are just coming off of drugs. Detox services usually include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The particular person in detoxification 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 treatment facility which can present detox services, the person will have detox staff at their disposal around the clock to make sure that any complications are handled as swiftly and safely as possible.
