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. Detoxification is basically the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold 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 detoxification facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual 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 detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detoxification services, the person will have detoxification staff at their disposal around the clock to make sure that any difficulties are resolved as rapidly and safely as possible.
