Drug screens for commercial drivers are federally mandated. That requirement doesn't seem to be going anywhere anytime soon (though maybe if marijuana becomes legal nationwide that will no longer be part of the test).

Agree with the rest of what you're saying though.

The test isn't going anywhere until there's a reliable field sobriety for weed. Companies don't want employees operating heavy equipment stoned, and unfortunately there's no way to test that somebody smoked in the last day or two, only that they've smoked in the last X weeks/months, depending on their habits.

no non-invasive ones, anyways. :(

blood test does fine for checking whether you're high at the time of draw.

Perhaps the technology will develop that enable finger sticks similar to those diabetes use, or transdermal readings.
