Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is frequently uncomfortable and may hold risks if not performed 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 treatment facility which can appropriately oversee and provide medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the individual is receiving proper rest, and providing supplements and medicine as required to make the detoxification process as smooth and safe as possible. The individual in detoxification 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 rehab facility which can offer detox services, the client will have detox staff at their disposal around the clock to make certain that any issues are handled as swiftly and safely as possible.
