Old medicines sitting around the house are a health and safety hazard, and flushing them or tossing them in the trash is bad for the environment.

What to do? Take your unused or expired pills to one of 1,700 dropoff sites on Saturday that are primed to take prescription or over-the-counter medications and properly dispose of them.  No liquid meds, just pills or powders.

Getting rid of unused medications prevents intentional misuse or abuse, and it also guards against accidental poisoning of children and pets who may get into them.  Flushing them down the sink or toilet, or throwing them away, merely transfers the risk to the environment, as they may get into streams from wastewater treatment plants or seep out of landfills into ground water.  For more on how pharmaceuticals are showing up in the environment, go here.

The U.S. Drug Enforcement Agency is sponsoring the drug take-back, to be held from 10 a.m. to 2 p.m.  Most, if not all, of the drop-off sites are police stations.  There are plenty throughout the Baltimore-Washington area.  For one near you, go here and enter your ZIP code (the city-state menu doesn't seem to be working).
