Individuals 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 basically the procedure of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detox services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to ensure that any issues are fixed as quickly and safely as possible.
