Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is generally uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can correctly oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services often include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detoxification will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can present detox services, the individual will have detox staff at their disposal around the clock to guarantee that any issues are resolved as quickly and safely as possible.
