People who are physically reliant to drugs or alcohol and want help will initially go through detoxification before getting other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is generally uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can adequately oversee and provide medical supervision for persons who are just coming off of drugs. Detoxification services usually include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and making certain the person 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 form of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can provide detoxification services, the individual will have detox staff at their disposal around the clock to ensure that any complications are handled as rapidly and safely as possible.
