The SM is "blowing smoke"...
UDS (Urine Drug Screen) will not detect nanogram levels equivalent to second hand smoke exposure.
His "unit" is doing no one a favor - including the UNIT. Just what we need, another lying, dope smoking, "soldier" holding a secret clearance and looking to do highly sensitive missions, unsupervised, that either enforce or direct US Foreign policy.
I hesitate to speculate, but he will probably need a "morals waiver" to get his packet past the initial review.
This shit just raises my blood pressure...
