For random testing situations, subbing would be your best bet.
Burnt Toast Reviewed by Burnt Toast on . jj Keller Just been informed that my company retained JJ Keller to perform random drug tests. Only worried about the THC and have read and currently testing N2's dilution method. Anyone familiar with JJ Keller and their routine? Are the just a management company and they still send you to a local test facility. Not sure when my number will come up buy would like to know what to expect. Rating: 5
