Yes it is "fake news" or bad science at the very least......  the Post is equating two trends happening simultaneously, increasing traffic fatalities and increasing evidence of MJ use in drivers bodies, and trying to draw a causal relationship without evidence.  Traffic fatalities are increasing nationwidewide, but that isn't mentioned, and this trend is in all states, not just where MJ is legal.  Bad reporting, bad journalism, obviously designed to mislead, not educate the public.
