Some cities have local dropoffs. I ended up sending an unopened inhaler to a program somewhere in the Midwest, I forget which program. This was when my PCP was trialing different inhalers & meds to rule out asthma and I realized how outrageous the retail price would be for anyone uninsured.

It has to be carefully documented and sealed of course.

Good luck. This is such a horrible waste.
