Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the process 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 needed. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for persons who are just coming off of drugs. Detox services often include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the particular person is getting proper rest, and supplying supplements and medicine as required to make the detox process as smooth and safe as possible. The individual in detox 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 rehabilitation facility which can supply detoxification services, the person will have detox staff at their disposal around the clock to assure that any complications are fixed as quickly and safely as possible.
