There are a lot of reasons to get rid of unused and unwanted medications around the house.

For families with kids, here's the main one: Unintentional poisoning killed 824 U.S. children in 2009 and 90 percent of them were teenagers, according to the Center for Disease Control and Prevention. Another 128,000 children visited emergency departments for poisoning-related injuries in 2010; half of them were teens.

Prescription drug abuse in teens is now at epidemic proportions with more than 7 percent of kids ages 12 to 17 reporting that they have used prescription drugs for non-medical reasons. In that age group, the prescription drug death rate has more than doubled from 1998 to 2008, the CDC says.

There are several opportunities this week to safely get rid of unused and unwanted medications, which also can contribute to contamination of waterways when they are flushed down the toilet, for instance.

So search through those medicine cabinets (and tell Grandma and Grandpa to do the same). Here's where you can drop it all off:

Safe Kids of Durham, along with local law enforcement, area businesses and the Drug Enforcement Administration are hosting Operation Medicine Drop starting this Thursday. Both prescription medication and illegal narcotics will be accepted (no questions asked)

“We want to provide the public a safe means of disposing unused and unwanted medications as well as illegal narcotics. No questions will be asked. By doing this, we can prevent accidental poisonings and drug abuse while protecting our waterways,” said Theresa Cromling, Safe Kids Durham County Coordinator, in a press release. According to Safe Kids, North Carolina’s death rate from unintentional poisoning is higher than the national average and is the second leading cause of injury in the state, the release said.

Safe Kids organizers also will be at the Museum of Life and Science in Durham from 10 a.m. to 2 p.m., Saturday,  to talk with parents about the hazards of prescription drugs. Duke University toxicologist Bryan Clark will create a simulated version of a waste water treatment facility and demonstrate how fish respond to toxins.

Here are the locations:
