People who are physically reliant to drugs or alcohol and want help will initially go through detox before getting other treatment services in drug rehab. Detoxification is basically the process of the drug being removed from one's system, which is often uncomfortable and may hold risks if not carried out in a setting which can provide appropriate support and medical intervention as necessary. Detoxification services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can properly oversee and provide medical supervision for individuals who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, supplying proper nutrition and making certain the individual is getting proper rest, and providing 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 type of physical activity such as walking, yoga, etc. At a drug detoxification facility or drug treatment facility which can offer detox services, the individual will have detox staff at their disposal around the clock to ensure that any problems are resolved as quickly and safely as possible.
