This is a round, slightly smaller than a dime in diameter and about as thick as 3/16 of an inch pill. it is some type of "oxy" label says oxyconteine/diene-codiene. i had a brief glance at the bottle before my brother took it and ran with it to hide it! The imprint is TEC and on the back side is a slight linear indention. What exactly is this pill and how potent is it? I need to know what he is into.
