I would really doubt you will be clean that fast. I certainly wouldn't rely on that for a new job. Sub. Its the safest way and the only 100% course of action.
killerweed420 Reviewed by killerweed420 on . GC/MS Testing at Labcorp Monday I am being tested for a new position at Labcorp and upon doing some research it appears they do the GC/MS test right off the bat. I am 5'4, weigh 100lbs, extreme metabolism and have been a fairly constant smoker forever now but will have 72 hours clean upon testing if I do use my own. I'm thinking of substituting just to be safe, however, a friend of mine who tests for parole uses Ready Clean with great results. I'm afraid that's because they do the simple cup test vs GC/MS. Any ideas? Rating: 5
