People who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can provide detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any problems are fixed as rapidly and safely as possible.
