Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is often uncomfortable and may carry risks if not carried out in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy 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 detoxification facility or drug rehabilitation facility which can offer detox services, the individual will have detox staff at their disposal around the clock to ensure that any problems are fixed as swiftly and safely as possible.
