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