An appraisal of chemical aversion (emetic therapy) approaches to alcoholism treatment.
More than 35,000 alcoholics have received chemical aversion (emetic therapy) in at least 75 settings worldwide since the 1930s. This consummatory aversion (CA) treatment, which pairs ethanol ingestion with emetically induced nausea, incorporates the highly efficient variety of learning known as taste aversion (TA) conditioning. The CA literature indicates that emetic therapy should induce conditioned alcohol aversions in many alcoholics. Such aversions have been widely reported by clinicians and have been confirmed by recent psychophysiological evidence. Long standing evidence of treatment effectiveness is found in the results of private hospitals which have consistently produced 1-yr abstinence rates approximating 60%. Diminished alcohol craving is a frequently reported benefit. Few experimental evaluations have been completed, as is generally the case for all alcoholism treatments, but those which used methodologically sound temporal parameters during conditioning have supported the clinical efficacy of emetic therapy. The clear need for more definitive research notwithstanding, there are compelling indications that emetic therapy is a useful component of multimodal treatment within certain alcoholic populations. However, its availability is severely limited. Many alcoholics could probably benefit from expanded treatment availability. The time is ripe for a reevaluation of resistances to the clinical use of emetic therapy alcoholism treatment.
