Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving 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 hold 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 effectively oversee and supply medical supervision for persons who are just coming off of drugs. Detox services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as wanted to make the detox process as easy and safe as possible. The person in detox 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 rehabilitation facility which can offer detoxification services, the person will have detox staff at their disposal around the clock to make sure that any issues are fixed as quickly and safely as possible.
