Oct. 28 is National Prescription Drug Take Back Day, which aims to help the public safely dispose of unwanted or expired prescription pills at sites throughout the country. Since 2010, the Drug Enforcement Administration event has collected more than 8.1 million pounds of pills, including opioid and other medications susceptible to diversion or misuse. DEA offers posters and other materials to help hospitals and others promote the event in their communities. Sites are open from 10 a.m. to 2 p.m. local time. To search for a site near you, click here.
