When my cat had her recent Expensive Dental Surgery, the vet gave me her pain medication already measured out in tiny little syringes. After hunting her down eight times and squirting it down her throat, I had eight tiny empty syringes.
Having previously decided to stop hoarding used syringes, I decided to get rid of them. Especially considering their capacity was 1.0 mL, which, if I haven't mentioned it, is tiny.
This seemed like the perfect opportunity to try out Freecycle. I posted that I had some used syringes to give away (no needles, thank you!) and within an hour and a half they were sitting on my porch in a plastic bag waiting for pickup.
I did get an email that said, "you should really just throw those away - not appropriate for reuse," but I chose to ignore that.
I may have committed a felony here, what with the transfer of medical waste and all, but I have eight fewer items in my home.
