Individuals who are physically dependent to drugs or alcohol and want help will first go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not executed in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug treatment facility which can correctly oversee and provide medical supervision for people who are just coming off of drugs. Detox services typically include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as required to make the detox process as smooth and safe as possible. The person in detox 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 treatment facility which can present detoxification services, the client will have detox staff at their disposal around the clock to assure that any difficulties are handled as quickly and safely as possible.
