I found pills too. It is sickening.
What other ways do we have of identifying them?
Calling your local poison control center is generally the quickest way to get an answer. They don't have everything but they do have most tablets/capsules. To call just dial 1-800-222-1222.
Do not give them a story, just ask for a pill to be identified and they should do it no questions asked unless it is something that is generally pretty sensitive for privacy issues such as HIV meds and such.
