The Police Department, the Board of Health, and the federal Drug Enforcement Administration are taking part in a national drug take-back initiative from 10 a.m. to 2 p.m April 28. Residents are invited to clean out their medicine cabinets and bring their expired, unused, and unwanted medications to Medford City Hall, 85 George P. Hassett Drive, during the event. The items will be disposed of properly, lessening the chances of drug abuse and theft. The disposal service is free and anonymous, with no questions asked. Items that will be accepted include pills, tablets, capsules, cough medicine, creams, and salves. Items that will not be accepted include needles and syringes, medical devices and instruments, and thermometers. The program is free and open to city residents only; no physicians or veterinarian offices. For more information, visit medford.org.
