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. Detoxification is basically the process of the drug being removed from one's system, which is often uncomfortable and may hold risks if not conducted in a setting which can supply appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The particular person in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as quickly and safely as possible.
