Individuals who are physically reliant to drugs or alcohol and want help will 1st go through detoxification before receiving other treatment services in drug rehab. Detoxification is simply the procedure of the drug being eliminated from one's system, which is frequently uncomfortable and may carry risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary.
