I can't weigh in on this until someone, anyone, shows me results the correlate a few things:

1) Time from medicating until you're less than 5 ng in your bloodstream. (i.e., if you medicate at 8 am, and at 3 pm go for a drive, you obviously aren't intoxicated, but what is your THC ng level?)

2) How does THC ng level correlate with level of intoxication? (i.e., if you medicate regularly, what is your THC ng level when you are completely sober and haven't medicated in 8 hours?)

Until answers like this are provided, I can't even begin to have an opinion as to whether the bill is fair or completely absurd. (Of course, starting from this completely ignorant position, I believe that the evidence must come before the bill sets the appropriate levels)
