People who are physically dependent to drugs or alcohol and want help will 1st go through detoxification before getting other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can supply appropriate support and medical intervention as required. Detox services are provided at either a professional drug or alcohol detox facility or a drug treatment facility which can appropriately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring 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 detoxification will sometimes be encouraged to take part in some form of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can provide detox services, the client will have detoxification staff at their disposal around the clock to make certain that any issues are resolved as quickly and safely as possible.
