I am very active, going to the gym everyday and jogging 3 miles at the local track. I looked up online that it said that the home drug tests cut-off is 50ng/ml, and the Military one is 15ng/ml.
The military uses an initial assay screen with a 50 ng cutoff limit and the confirmation GC/MS with a 15 ng limit. They'll run the confirmation test if the sample tests positive for THC on the initial screen.

Read my post in this thread. You'll discover that even though their cutoffs numerically differ, a 50 ng assay is functionally equivalent to the 15 ng GC/MS....http://boards.cannabis.com/drug-test...ml#post2146908
