There's a great book about (what might be) the general problem here: that there are many factors that keep us at a bad equilibrium, where a bunch of people would have to change at once to accomplish anything.
Here, I think it's something like, "insurers move very slowly to new systems, and until this new testing has a lot of data behind it, they won't adjust premium. to account for it being better. Furthermore, juries will continue to give punishingly big damage awards for using it, on the mistaken believe that a toker shouldn't be on the job even if he wasn't high and passed the reaction test."
