Men and women who are physically reliant to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detox is simply the procedure of the drug being eradicated from one's system, which is typically uncomfortable and may carry risks if not conducted in a setting which can offer appropriate support and medical intervention as required. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and present medical supervision for individuals who are just coming off of drugs. Detoxification services usually include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and ensuring the individual is receiving proper rest, and providing supplements and medicine as wanted to make the detoxification process as smooth and safe as possible. The individual in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to make sure that any issues are resolved as quickly and safely as possible.
