People who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services generally include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is receiving proper rest, and providing supplements and medicine as needed 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 treatment facility which can provide detox services, the client will have detox staff at their disposal around the clock to ensure that any issues are resolved as quickly and safely as possible.
