Individuals who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may carry risks if not carried out in a setting which can provide appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services frequently include insuring the person 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 providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The person 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 treatment facility which can provide detox services, the individual will have detoxification staff at their disposal around the clock to make sure that any complications are fixed as rapidly and safely as possible.
