Individuals who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before getting other treatment services in drug rehab. Detox is basically the procedure of the drug being removed from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and provide medical supervision for persons 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, providing proper nutrition and ensuring the particular person 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 sort of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can supply detoxification services, the individual will have detoxification staff at their disposal around the clock to make sure that any difficulties are resolved as quickly and safely as possible.
