Individuals who are physically reliant to drugs or alcohol and want help will initially go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as needed. Detox 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 client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing 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 particular person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detoxification services, the individual will have detoxification staff at their disposal around the clock to make sure that any issues are handled as quickly and safely as possible.
