Men and women who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the process of the drug being eliminated from one's system, which is typically uncomfortable and may carry risks if not performed in a setting which can offer appropriate support and medical intervention as required. Detoxification services are provided at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and supply medical supervision for individuals who are just coming off of drugs. Detox services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the particular person is getting proper rest, and providing supplements and medicine as wanted to make the detoxification 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 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 issues are fixed as quickly and safely as possible.
