Individuals who are physically reliant to drugs or alcohol and want help will initially 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 often uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can properly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the individual is getting proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detox 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 rehab facility which can present detox services, the person will have detoxification staff at their disposal around the clock to assure that any complications are resolved as swiftly and safely as possible.
