A major problem for diabetes is what to do with you testing materials, and if you are using insulin what to do with the sharps The trash is not the correct answer as they are considered biomedical hazards.
I have found I can get the container at a local pharmacy and they are inexpensive. I could probably ask my pharmacy for one but that is a pain. The Valley Medical pharmacy does have a sharps return bin such as seen here. It is a pain to carry them from home, but I have a sharps container at home and one at work, which is at Valley MediCal Center.
