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 basically the process of the drug being eliminated from one's system, which is usually uncomfortable and may hold risks if not carried out in a setting which can supply appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can adequately oversee and supply medical supervision for people who are just coming off of drugs. Detox services generally include insuring the person is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and ensuring the person is getting proper rest, and providing supplements and medicine as necessary to make the detox process as easy and safe as possible. The particular person 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 rehab facility which can provide detox services, the client will have detox staff at their disposal around the clock to make certain that any complications are fixed as rapidly and safely as possible.
