Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and supply medical supervision for individuals 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, offering proper nutrition and making certain the individual is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual 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 treatment facility which can present detoxification services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are fixed as rapidly and safely as possible.
