From the Dallas Morning news a few years back:
Drug Testing Losing Favor with Employers
Those who want a job in America with Plano-based Electronic Data Systems Inc. must hand over a hair sample for drug testing – in addition to a well-crafted resume and solid references.
Across the Canadian border, however, hair samples aren’t required at EDS locations. “Because of cultural differences, it’s not as accepted there, and we would no longer be considered a preferred employer,” said EDS spokeswoman Leslie Hueholt.
“It would apparently impact our ability to recruit in Europe and Canada.”
I'm screwed unless they take ear hair.
