Do they drug test family members before placing with them?

I see. I guess I wouldn't be surprised is they did not test the aunt. In thinking about this whole thing, I also consider the fact that aunt has 4 children of her own..all in her own care. She is living with her soon-to-be exhusband's parent's with all her children. I'm guess his parents can't be too bad of people if they kicked their own son out before kicking aunt and her 4 kids out on the street. I always wonder about some of the bioparents and their family members we meet. I wonder if the face they put on in front of us and the SW's is so well practiced that they are able to fool us. It isn't like me to be judgmental and suspicious, but I learned quickly from our previous biomom that all is not what it seems.
