People who are physically dependent to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is often uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can effectively oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is getting proper rest, and providing 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 detoxification facility or drug rehabilitation facility which can present detoxification services, the individual will have detox staff at their disposal around the clock to make sure that any problems are fixed as quickly and safely as possible.
