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 basically 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 offer appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detox services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as needed to make the detox process as smooth 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 rehabilitation facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to ensure that any difficulties are resolved as quickly and safely as possible.
