People who are physically dependent to drugs or alcohol and want assistance will 1st go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can provide appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services frequently include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can supply detox services, the individual will have detox staff at their disposal around the clock to ensure that any difficulties are fixed as quickly and safely as possible.
