The national drug testing standard is 50NL.


A reading in the 85NL range is still too high, but 15 is low. If you came in at under 50 but over 15 I would fight it if the job were worth it. It is actually amazing you only had 82 NG/NL in you if you stopped just before the test.

You really should allow a month if you are not physically active and smoke often.
