Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not executed in a setting which can supply appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the individual will have detoxification staff at their disposal around the clock to guarantee that any difficulties are resolved as quickly and safely as possible.
