Brummett CM, Steiger R, Englesbe M, et al. Effect of an Activated Charcoal Bag on Disposal of Unused Opioids After an Outpatient Surgical Procedure: A Randomized Clinical Trial. JAMA Surg. 2019;154(6):558-561. doi:10.1001/jamasurg.2019.0155
  • 6% of patients who received usual care reported disposing of opioids, compared with 33.3% who received education regarding disposal locations and 57.1% of patients who received a charcoal activated bag.
  • The odds of opioid disposal were almost four times higher among participants who received a charcoal bag compared with those who received usual care.
