Individuals who are physically reliant to drugs or alcohol and want assistance will initially go through detoxification before getting other treatment services in drug rehab. Detoxification is simply the procedure of the drug being removed from one's system, which is frequently uncomfortable and may hold risks if not executed in a setting which can offer appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detox facility or a drug rehab facility which can appropriately oversee and supply medical supervision for people who are just coming off of drugs. Detox services frequently include insuring the individual is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, delivering proper nutrition and ensuring the individual is getting proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The individual 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 treatment facility which can present detox services, the person will have detoxification staff at their disposal around the clock to ensure that any difficulties are resolved as rapidly and safely as possible.
