Individuals who are physically reliant to drugs or alcohol and want help will first go through detox 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 performed in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detox services frequently 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 wanted to make the detoxification process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the person will have detoxification staff at their disposal around the clock to make sure that any difficulties are fixed as quickly and safely as possible.
