Because it wasn't legal at all anywhere in the US a couple years ago, so the test only needed to determine if you'd been using it period.
IF it gets federally legalized, and IF the DOT (and DOD, and DOJ, etc) decide that it's OK to use, then they'll have to figure out how much you can smoke, how long ago, and develop a test for that specifically.
Don't hold your breath (pun intended), the feds will not be falling all over themselves to ensure the rights of airline pilots, soldiers, and cops to blaze up. That will take an act of congress.
