Individuals who are physically reliant to drugs or alcohol and want help will 1st go through detox before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can offer appropriate support and medical intervention as required. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and provide medical supervision for people who are just coming off of drugs. Detoxification services generally include insuring the person is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is receiving proper rest, and providing supplements and medicine as wanted to make the detox process as smooth and safe as possible. The individual in detoxification will sometimes be encouraged to take part in some kind of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehabilitation facility which can present detox services, the client will have detox staff at their disposal around the clock to assure that any difficulties are resolved as quickly and safely as possible.
