i remodel apartments and i find alot of random pills left behind by former tenants. i found a bottle of pills that have 160 on one side and OC on the other, they are shaped like a capsule,
it looks just like this but with the imprints i described
160 OC is 160mg Oxycontin, they're not made anymore and were only available for a short time since people were overdosing and dropping like flies, they're nicknamed blue coffins.
