I found almost half of a large, white, oval pill (or mint?) that is close to a half inch long, with 'almost diamond-shaped' horizontal lines on one side & no imprint on the other side. It's about 1/4 inch thick. I detect no odor. My roommate said he found it on our floor, so he put it on the counter... where my young child nearly ate it, thinking it was a mint!! (She asked if she could have the mint on the counter. I thought she meant a red & white peppermint candy. Thank the heavens I turned towards her & prevented her from eating it). If this is a pill, my friend is getting kicked out.
