Men and women who are physically dependent to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is basically the procedure of the drug being eliminated from one's system, which is generally uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and supply medical supervision for persons 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, providing proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as necessary 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 rehabilitation facility which can provide detoxification services, the client will have detox staff at their disposal around the clock to make sure that any issues are resolved as swiftly and safely as possible.
