I found a small round pink pill in my daughters room. It has a flat line on the back and what looks like a jagged 3 or z over a line on the other side. I was told it was a 70 mg phentermine but I cant find it on any website.
Check out this thread talking about a pill from Mexico (supposedly). Let us know if the image matches the logo on the tablet you found in your daughter's room. Maybe we can get this puzzle solved:
