Individuals who are physically reliant to drugs or alcohol and want help will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the person is getting 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 sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can provide detox services, the individual will have detox staff at their disposal around the clock to guarantee that any difficulties are resolved as quickly and safely as possible.
