People who are physically reliant to drugs or alcohol and want assistance will 1st go through detox before receiving other treatment services in drug rehab. Detox is simply the process of the drug being eradicated from one's system, which is generally uncomfortable and may carry risks if not carried out in a setting which can offer appropriate support and medical intervention as needed. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehabilitation facility which can adequately oversee and provide medical supervision for men and women who are just coming off of drugs. Detoxification services usually include insuring the client is as relaxed as possible while detoxing and going through drug or alcohol withdrawal, providing proper nutrition and making certain 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 person in detoxification will sometimes be encouraged to take part in some variety of physical activity such as walking, yoga, etc. At a drug detox facility or drug rehab facility which can offer detoxification services, the client will have detox staff at their disposal around the clock to ensure that any problems are fixed as rapidly and safely as possible.
