Proper drug disposal programs accept expired, unwanted, or unused medicines from designated users and dispose of them responsibly. Programs can use in-person drop-offs, mail-in efforts, or permanent secure collection receptacles and can be administered by state or local governments, municipal trash and recycling services, pharmacies, hospitals, clinics, or community organizations partnered with law enforcement. A 2014 amendment to the federal Controlled Substances Act allows the US Drug Enforcement Administration (DEA) to register authorized collectors of controlled substances, allowing collection of pharmaceutical controlled and non-controlled substances, but not illicit drugs1.
Expected Beneficial Outcomes (Rated)

Increased appropriate drug disposal
Evidence of Effectiveness
Proper drug disposal programs are a suggested strategy to reduce illicit drug use and unintentional poisoning2, 3, 4, reduce pharmaceutical contamination of fresh water, and improve water quality5, 6, 7, 8, 9. Available evidence suggests that drug disposal programs increase collection and proper disposal of unused prescription drugs10, 11, 12, 13, 14, 15 and reduce pharmaceuticals in the environment16. However, additional evidence is needed to confirm effects on drug use and water quality.
Ongoing statewide drug disposal programs with permanent collection receptacles may more effectively prevent drug abuse and accidental poisoning than temporary, one day take-back events7, 3. Surveys suggest that community campaigns to raise awareness about drug take-back events increase use of disposal programs and conversations with children about the dangers of prescription drug abuse17. Overall, the US Food and Drug Administration (FDA) suggests disposing of unneeded medicine through organized programs or take-back events; however, the FDA also suggests flushing specific harmful drugs to prevent accidental ingestion or misuse4.
Many federal agencies and experts suggest that individual households, hospitals, and health care facilities avoid flushing any pharmaceuticals to preserve water quality and protect aquatic life and ecosystems18, 19. Active pharmaceutical ingredients (APIs) released into the environment via improper disposal (e.g., flushing or landfill leaching) can adversely affect aquatic life, contaminate freshwater resources, and promote drug resistance in bacteria20, 21, 9. Flushing unused pharmaceuticals can cause spikes in APIs in the environment7; flushed pharmaceuticals may also break down into compounds that have different toxicity levels than the original drug5. Over 80% of sampled US streams have evidence of pharmaceuticals in the water8, 22.
Patient and pharmacist education may be needed to reduce improper drug disposal and increase use of proper disposal programs23, 24. Benefit cost analysis suggests that establishing a proper drug disposal program would yield positive net social benefits25; ongoing bin-based programs appear to be more cost-effective than mail-in programs or one day events26.
Impact on Disparities
Several states have legislation that authorizes and guides proper drug disposal programs for consumers such as Maine27, Ohio28, and Washington29. Some states have legislation that prohibits health care institutions from flushing unused medications into public wastewater as in Illinois30. Other states provide public guidelines and educational materials about proper drug disposal such as Connecticut31, Florida32, New York33, and New Jersey34.
The DEA has two drug take-back events each year; since 2010, the DEA has collected 4.8 million pounds of prescription drugs on only 9 days35. In 2016, at the most recent take-back event, the DEA set a new record, collecting about 447 tons at almost 5,400 sites in all 50 states36. Sheriff’s offices also host regularly scheduled drug take-back programs for the public. Operation Medicine Cabinet in Broward County, Florida is one example37.
October 22nd is National Prescription Drug Take-Back Day; in 2016, more than 5,000 collection sites nationwide participated. Private organizations have also established permanent drug disposal receptacles. For example, Walgreen’s pharmacy has over 500 collection kiosks at pharmacies in 35 states and Washington DC38.
