  2. A reflection of concern…

  3. Pharmaceuticals • Wide range of biologically-active chemicals • 5-10% designate as hazardous waste • A different 5-10% are Controlled Substances -- challenging to manage

  4. Pharmaceuticals (cont’d) • Controlled Substances – regulated by the Federal Drug Enforcement Administration due to potential for abuse • Schedule I – illegal drugs (ex., heroin, LSD) • Schedule II – morphine, OxyContin, codeine, Demerol, Ritalin, amphetamines, fentanyl • Schedule III – Tylenol with codeine, Vicodin • Schedule IV – benzodiazepines, Valium, Darvon, phenobarbital • Schedule V – codeine cough syrups

  5. Some Pharmaceuticals are Endocrine Disrupting Chemicals

  6. Drugs are showing up in the environment • Ibuprofen, valium, prozac, antibiotics, steroids, hormones • Found in 80% of U.S. streams tested by USGS • Found in drinking water supplies in many U.S. cities

  7. Drugs in the environment(cont’d) • Antibiotics, hormones, SSRIs are receiving the most attention. • Boulder Creek, CO, study: 50:50 female:male ratio upstream, 90:10 downstream; ethynyl-estradiol measurably higher downstream. • Male fish are producing eggs in many places.

  8. Drugs in the environment(cont’d) • Bioassays of SSRIs are showing some sub-lethal effects at environmentally- relevant levels. • 2006 Italian study found that a mixture of common drugs at very low (ng/L - environmentally-relevant) concentrations inhibited the growth of human embryonic cells Clean water 50 ppb fluoxetine

  9. Drugs enter the environment through use and disposal • Probably most result from use, passing through us un-metabolized, then going through wastewater treatment systems • Unused/unwanted quantities could be huge, as much as 50% of many prescriptions (80% for antibiotics) • Common/historical recommendation was to flush; “crush&flush” is still widely practiced method

  10. Too Many Drugs Go Unused • PhRMA uses an estimate of 3% of all meds go unused • British survey showed: • 82% of antibiotics go unused • 50% of antidepressants “ • 50% of beta-blockers “ • 20% of pain meds “ [Ref: Bound & Voulvoulis, 2005] • Austria & Germany • 25-33% go unused [Source: Kummerer, K., 2004]

  11. Unused Accumulations (cont’d) • Compliance/adherence rates for some medications are under 20% • Patient compliance goes down as # of medications goes up: “polypharmacy” • Medicare Part D now requires 30-day supply billings, regardless of need and without ability to refund unused expenses (or to return unused product)

  12. Unused Accumulations (cont’d) • Hospice nurses, nursing homes and medical examiners are faced with large accumulations of medicines, including potent controlled substances, when patients die • “Catch 22” for handling the left-overs – no easy, safe, legal or environmentally acceptable answers

  13. Drug sales have skyrocketed U.S. sales have more than doubled in last 5 yrs (Ref: National Drug Intelligence Center, 2005, via Ilene Ruhoy, 2006)

  14. Increased Sales= More Exposure • From 1993 to 2003 the US population increased 13% • prescriptions purchased increased 70% • prescriptions/capita increased 7.8 to 11.8. [Source: Kaiser Family Foundation, October 2004]

  15. Increased Sales (cont’d) Prescription Opiates Sold in King County Percent Change 1997-2003 Source- ARCOS/DEA Data for Zip Codes 980xx and 981xx, which approximates King County boundaries http://www.deadiversion.usdoj.gov/arcos/retail_drug_summary/index.html

  16. Poisonings • Of all calls to U.S. poison control centers in 2004: • 2,438,644 total exposures reported • 1,389,156 (57%) were pharmaceutical exposures • 581,488 (42%) of the pharm exposures were to children under 6 years of age

  17. Poisonings (cont’d)

  18. Diversion & Abuse • Between 1992 and 2003: • # of teens (12 to 17 yrs of age) who abused controlled drugs jumped 212% • One in five teens says he or she has been offered prescription drugs to get high • # of all Americans who abuse controlled prescription drugs nearly doubled, from 7.8 million to 15.1 million (Ref: CASA, 2005)

  19. Diversion & Abuse (cont’d) • Increasing popularity of prescription narcotics over Schedule I drugs (perceived to be “safer”) • Most teens get their prescription drugs from home or friends • OxyContin street value now = $80 per pill

  20. Drug Abuse (cont’d)Drug Involved Deaths, King County Rx

  21. Trash (MSW) is not the option • White House Office of Drug Control Policy says mix with coffee grounds and throw in the trash • Not secure: still available to children, pets, homeless, solid waste workers • Landfills (80% of U.S. solid waste) still produce liquid leachate, which often goes to municipal wastewater plants

  22. Unfunded mandate • Problem wastes should not be the responsibility of local government and local tax-/rate-payers • A product stewardship approach is needed

  23. Summary of Concerns • Lots of unused drugs in people’s homes • Poisoning and abuse concerns • Low compliance = high accumulations • Left-overs are routinely flushed • Drugs are showing up in the environment • No safe, legal, environmentally-acceptable options exist • Local governments should not have to foot the bill
