Individuals who are physically dependent 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 generally uncomfortable and may hold risks if not performed in a setting which can supply appropriate support and medical intervention as needed. Detoxification services are provided at either a professional drug or alcohol detoxification facility or a drug treatment facility which can correctly oversee and present medical supervision for persons who are just coming off of drugs. Detoxification 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 person is getting proper rest, and providing supplements and medicine as necessary 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 rehab facility which can offer detox services, the person will have detox staff at their disposal around the clock to ensure that any problems are handled as swiftly and safely as possible.
