Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detox before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is typically uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can effectively oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain the individual is getting proper rest, and providing supplements and medicine as necessary to make the detoxification process as easy and safe as possible. The individual 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 rehab facility which can present detox services, the client will have detox staff at their disposal around the clock to assure that any difficulties are handled as rapidly and safely as possible.
