Drug detoxification (informally, detox) is variously the intervention in a case of physical dependence to a drug; the process and experience of a withdrawal syndrome; and any of various treatments for acute drug overdose.
A detoxification program for physical dependence does not necessarily address the precedents of addiction, social factors, psychological addiction, or the often-complex behavioral issues that intermingle with addiction.
The United States Department of Health and Human Services acknowledges three steps in a drug detoxification process:
The principle of rapid detoxification is to use heavy sedation alongside dosing with opioid antagonists. This approach is expensive, ineffective and extremely dangerous.
The concept of "detoxification" comes from the discredited autotoxin theory of George E. Pettey and others. David F. Musto says that "according to Pettey, opiates stimulated the production of toxins in the intestines, which had the physiological effect associated with withdrawal phenomena... Therefore treatment would consist of purging the body of toxins and any lurking morphine that might remain to stimulate toxin production in the future."
Naltrexone therapy, which critics claim lacks long-term efficacy and can actually be detrimental to a patient's long-term recovery, has led to controversy. Additionally, there have been many questions raised about the ethics as well as safety of rapid detox following a number of deaths resulting from the procedure.
