Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting 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 carry risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detox services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The person in detox 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 treatment facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to ensure that any issues are fixed as rapidly and safely as possible.
