Individuals who are physically reliant to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is simply the process of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as necessary. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can properly oversee and provide medical supervision for people who are just coming off of drugs. Detox services usually include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detox services, the person will have detoxification staff at their disposal around the clock to make sure that any problems are handled as quickly and safely as possible.
