Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can correctly oversee and present medical supervision for persons who are just coming off of drugs. Detoxification services typically include insuring the person is as relaxed 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 necessary to make the detox process as smooth and safe as possible. The person in detox will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detox services, the client will have detox staff at their disposal around the clock to ensure that any problems are fixed as quickly and safely as possible.
