Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detox before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eradicated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the individual is getting proper rest, and providing supplements and medicine as needed to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the individual will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as rapidly and safely as possible.
