Just got off the phone with a friend. He ran an eight man well (gas) tending crew here in WV over the winter. Thirteen men hired and fired in six months...on a single, eight man crew. They were clean for hiring, but failed the random tests. Said he never had a problem with any of them in the field, but once they failed the random, they were gone.
I jokingly told my husband I was going to open a head shop that sold synthetic urine. Seems everyone down here smokes weed.
