People who are physically dependent to drugs or alcohol and want help will 1st go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detox services generally include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the particular person is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detoxification services, the person will have detox staff at their disposal around the clock to ensure that any issues are resolved as swiftly and safely as possible.
