People who are physically dependent to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and supply medical supervision for men and women who are just coming off of drugs. Detox services typically include insuring the client is as comfortable 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 required to make the detoxification process as easy and safe as possible. The individual 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 rehabilitation facility which can present detoxification services, the person will have detox staff at their disposal around the clock to ensure that any issues are fixed as swiftly and safely as possible.
