I have a love hate relationship with AARP but this is a good article with a fabulous idea.
http://www.aarpmagazine.org/health/old_pills.htmlEvery year we flush at least $1 billion in prescription drugs down our toilets. We pour them into incinerators; we bury them in landfills. But Moshe Alamaro, an inventor and researcher at MIT with not-just-big-but-colossal ideas—such as building 200-foot ice mountains to fight water shortages—believes he has a solution for unused pharmaceuticals. "We recycle glass and plastic," the silver-haired Alamaro said one recent afternoon, wearing owlish glasses and sitting among the stacks at the MIT library. "Why all the apprehension about doing the same for a bottle of pills?"

Alamaro's plan entails nothing less than wholesale changes to how we think about packaging, distributing, and consuming prescription drugs. Pills would come in tamperproof packs and include a bar code or radio frequency ID to provide such details as dosage amounts and expiration date; a chemical agent would record the drug's exposure to heat and light (which can make many medicines less effective). The packs would be loaded in a Pez-like dispenser, ensuring that unused pills would be untouched and safe for recycling. Patients could then return their medications to processing centers via a drop box or prepaid mailer. The centers would inspect the drugs, and pills in good condition would be available for redistribution.
