Men and women who are physically reliant to drugs or alcohol and want assistance will 1st go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the procedure 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 supply appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and supply medical supervision for persons who are just coming off of drugs. Detoxification services typically 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 receiving proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can present detox services, the individual will have detoxification staff at their disposal around the clock to assure that any problems are fixed as quickly and safely as possible.
