People who are physically dependent to drugs or alcohol and want assistance will 1st go through detoxification before receiving other treatment services in drug rehab. Detox is simply the process of the drug being removed from one's system, which is generally uncomfortable and may carry risks if not conducted in a setting which can supply appropriate support and medical intervention as needed. Detox services are supplied at either a professional drug or alcohol detox facility or a drug rehab facility which can correctly oversee and supply medical supervision for individuals who are just coming off of drugs.

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 detox facility or drug treatment facility which can supply detoxification services, the client will have detox staff at their disposal around the clock to ensure that any complications are fixed as rapidly and safely as possible.
