Throwing Away Old Medications Benefiting For Environment
A new study suggests that dumping old or unneeded medications in the trash can may be the best way to reduce the environmental impact of the 200 million pounds of pharmaceuticals that go unused in the U.S. each year. The report, which weighs the emissions from flushing, incinerating or trashing drugs, appears in ACS' journal Environmental Science & Technology.
Stephen J. Skerlos and colleagues explain that to avoid the risks of abuse and accidental poisoning, as well as other problems that unused, unwanted or expired pharmaceuticals pose, they shouldn't be kept in homes. If thrown away or flushed down a toilet, however, antibiotics, hormones and other drugs can get into lakes, rivers and other water supplies, where they can affect humans and animals. Some places in the U.S. have recently started take-back programs, in which pharmacies collect unneeded drugs and incinerate them with other medical waste, but this burning and transportation produces greenhouse gases and other pollution. The authors wanted to assess the different disposal methods to see which might make the most sense for U.S. households.
