To ensure they do not find themselves in trouble and to prevent harm to the environment, Airmen and family members can dispose of expired or unneeded medications in the commissary during a drug take-back day at Ellsworth Air Force Base, S.D., Oct. 26, 2013, from 10 a.m. to 12:30 p.m. Take-back days are done twice a year and are designed to give individuals an opportunity to get rid of any controlled or uncontrolled substances in a safe manner.
