I read this from Richmond Review and I found it totally make sense. It's very important that we dispose unwanted medication properly instead of flushing it down the drain or throwing it away in the garbage.

Too many people toss old medications in the trash or flush them down the drain instead of using an existing return program, according to Metro Vancouver.
Pharmaceuticals that end up in landfills or in the sewer system can make their way into the environment. There it's feared they can poison or disrupt hormone levels and normal reproductive cycles in aquatic life, and potentially contribute to the rise of antibiotic-resistant bacteria.
Eliminating expired or unwanted drugs from medicine cabinets also ensures they aren't someday consumed by accident.
So looks like we can dispose wide range of unused medicines, including prescription drugs, nonprescription and herbal products, and vitamins and mineral supplements at most B.C. pharmacies
Just take the unwanted, used, expired, and old drugs to any local pharmacies and they are happy to take them from you. They will not reuse them, don't worry. They have proper ways to disposal them.
