However, if you smoke/eat/inhale and drive you can now be prosecuted as a dui (even if you smoked it last week)...not a misdemeanor $100 ticket but more like 5k in fines/attorney/court fees and higher insurance rates....Who wins...attorneys and insurance corporations.
you could always get a dui for smoking. before medical, after medical, before recreational, and now of course after.
the only difference now is i believe the WA authorities have created some sort of ppm scale or something like that that can somewhat reasonably detect the saturation of thc in the blood. i am somewhat dubious.
a dui for smoking never was a misdemeanor $100 ticket. its cuffs and a free ride, diversion, etc. unfortunately i know from experience (although OR)
