Background: Organized disposal of controlled medications, such as take-back events and permanent drug donation boxes, is a prevention strategy that has been widely used to reduce the availability of controlled medications for diversion or abuse. However, little is known as to whether this strategy actually reduces the overall availability of these medications for the purposes of diversion or abuse. Objectives: The objective of this study was to compare the number and types of controlled medications that were disposed through organized efforts to the number dispensed in local communities. Methods: The quantity and type of controlled medication collected from three take-back events and permanent drug donation boxes over 4-week-long periods in five counties in south-central Kentucky was measured and compared to the number of controlled medications dispensed, as reported by Kentucky All Schedule Prescription Electronic Reporting system. Results: In 2013, 21,121,658 controlled medications units were dispensed in the participating counties. Of those, 46.9% were opioid analgesics, 13.1% tranquilizers, and 37.3% "other." During the assessment periods, a total of 21,503 controlled medication units were collected. Of those, 39.9% were opioid analgesics, 2.7% tranquilizers, and 57.4% "other." Annually, controlled medications disposed were estimated to account for 0.3% of those dispensed. Conclusion: Controlled medications collected by take-back events and permanent drug donation boxes constituted a miniscule proportion of the numbers dispensed. Our findings suggest that organized drug disposal efforts may have a minimal impact on reducing the availability of unused controlled medications at a community level.
