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 simply the process of the drug being removed from one's system, which is typically uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as required. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and present medical supervision for persons who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as required to make the detox process as easy 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 rehab facility which can offer detoxification services, the individual will have detox staff at their disposal around the clock to make certain that any difficulties are handled as quickly and safely as possible.
