Individuals who are physically dependent 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 often uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and present medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the person 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 smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to make sure that any issues are handled as rapidly and safely as possible.
