National screening Center Bruce Jefferies failed my hair test, my hair test for 12/11/2018 was positive at level >20,000 for cocaine , im so disappointed . Houston Texas
I been doing their for 6 months now, I failed 4 hair follice test the Subsances was still in my system but my level was dropping, 3 months ago my hair test was clean up until 12/11/2018, I believe National screening Center is switching hair follicle test, once we leave the facility
