: Is there anything that will make a hair follicle test come back positive for opiates? There has been one in my family and there has been no drug usage. How does that happen?

I've heard that eating poppyseeds (in muffins, etc) can cause positive results for opiates in urinalysis; i'm not sure if this carries over to hair follicle tests though.
