People who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification 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. Detoxification services are supplied at either a professional drug or alcohol detox facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for individuals who are just coming off of drugs. Detox services generally include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as required to make the detox process as easy and safe as possible. The individual in detox will sometimes be encouraged to take part in some type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug rehab facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to ensure that any issues are fixed as quickly and safely as possible.
