People who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as needed. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for people 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 receiving proper rest, and supplying supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can offer detox services, the person will have detoxification staff at their disposal around the clock to ensure that any complications are fixed as quickly and safely as possible.
