Individuals who are physically reliant to drugs or alcohol and want assistance will 1st go through detoxification before getting other treatment services in drug rehab. Detox is basically the process of the drug being removed from one's system, which is often uncomfortable and may hold risks if not performed in a setting which can offer appropriate support and medical intervention as needed. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug treatment facility which can appropriately oversee and provide 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, offering proper nutrition and ensuring the person is getting proper rest, and supplying supplements and medicine as required to make the detox process as easy 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 detoxification facility or drug rehab facility which can present detox services, the person will have detox staff at their disposal around the clock to assure that any complications are fixed as rapidly and safely as possible.
