Individuals who are physically dependent to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is simply the process of the drug being removed from one's system, which is typically uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are supplied at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services often include insuring the individual is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as required to make the detoxification process as easy and safe as possible. The person in detox 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 treatment facility which can present detoxification services, the client will have detox staff at their disposal around the clock to assure that any issues are handled as rapidly and safely as possible.
