Individuals who are physically dependent to drugs or alcohol and want assistance will first go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the process of the drug being eliminated from one's system, which is frequently uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detox facility or a drug treatment facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detoxification services typically include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the particular person is getting proper rest, and providing supplements and medicine as needed to make the detox process as smooth and safe as possible. The person 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 treatment facility which can provide detoxification services, the person will have detox staff at their disposal around the clock to ensure that any difficulties are resolved as swiftly and safely as possible.
