Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not executed in a setting which can provide appropriate support and medical intervention as required. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and present medical supervision for people who are just coming off of drugs. Detoxification services frequently 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 necessary to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some variety 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 detoxification staff at their disposal around the clock to assure that any complications are resolved as quickly and safely as possible.
