People who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detoxification 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 usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detox 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 rehabilitation facility which can present detox services, the client will have detoxification staff at their disposal around the clock to guarantee that any problems are handled as quickly and safely as possible.
