Ok im going to shed a little light on this. Im active duty military. Whenever i go to any hodpital they copy my id card. That is my insurance card. That copy goes to tricare in exchange for payment. Tricare then notifies my unit surgeon who is required to notify my commander. Once that happens (usually 24hrs after checking in) my CO is required to have me take a UA within 24hrs. Lets add this up, 24+24=48. Meth stays in your system for 72hrs minimum. How do i know all this? Im the primary guy that does the piss testing! As for the behavior differences....how many combat vets with tours in both iraq and afghanistan have you seen come off this stuff? I know i have PTSD. Probably have had some mild TBI's in the past. Oh and by the way, the military is in a draw down and looking for reasons to get rid of people. Another motivating factor behind me getting clean. UA's have been doubled.
