I once lumped all my leftover meds together in a baggy and sent them to a place that would dispose of them. Another time the cop shop had a drop off for all old meds. That was a bit of a paranoid issue though. Now I just have what I use

Latuda 3 different doses
Lamictal just the one dose
Ambien (I kinda hord those)
Propranolol I went from 3 an day to 2 a day so I've extra
Cholesterol drug
Thyroid drug

I feel like a druggy when I go though the airport, I get all my drugs three months at a time so the bottles are big
