I haven't had any iris only boxes open, nor seeds. But when a box contained some bread seed poopy pods the drug dog sniffed it out. It was interesting actually. I got a letter from the PO in Woodland which is nesr Sacramento. The drug dog seems to be located there. They opened the box and checked the seeds.
Because I was then quite curious, i read up on those poppies and discovered the pod is what is used to make opium. Not the seed as I had thought. Thus the seed pods were picked out by the dog.
