what is a white round pill, 1/4" diameter, number 81 on one side, no other
markings on either side; the "8" is just as shown here, with top circle of the
8 smaller than the bottom. The "1", also is as shown here with small diagonal slash from the top of the 1; both facts making clear that I'm not looking at an
inverted "18". Am concerned about whether this pill is my son's or an acci-
dental dropped pill of the previous tenant in this house we just moved into.
Hoping it's something legit that no healthy teen would have any use of or
desire for, helping me determine for sure whether it could be his or not before I ask him. Can anyone out there help me?
