Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed 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 needed. Detoxification services are supplied at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and provide medical supervision for persons 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, providing proper nutrition and making certain the person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detoxification services, the client will have detoxification staff at their disposal around the clock to make sure that any issues are resolved as rapidly and safely as possible.
