Men and women who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detoxification is simply 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 offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and present medical supervision for men and women who are just coming off of drugs. Detoxification services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the individual is getting proper rest, and providing supplements and medicine as needed to make the detoxification process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detox services, the person will have detox staff at their disposal around the clock to ensure that any issues are resolved as quickly and safely as possible.
