Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is basically the procedure of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and present medical supervision for people who are just coming off of drugs. Detoxification services usually include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the individual is receiving proper rest, and supplying supplements and medicine as needed to make the detox process as smooth and safe as possible. The person in detoxification 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 treatment facility which can offer detox services, the client will have detox staff at their disposal around the clock to make sure that any issues are fixed as quickly and safely as possible.
