Marijuana DUI Bill Clears Big Colorado Hurdle

[Ohio Joe]

DENVER -- A marijuana blood standard for drivers appears headed for approval in Colorado -- thanks to a single vote change from a Republican senator.

Sen. Nancy Spence of Centennial voted Tuesday in favor of the plan to consider drivers impaired if they test positive for 5 nanograms or more of THC, the psychoactive ingredient in marijuana, per milliliter of blood.

Spence's decision gave the bill the support it needed to advance on a vote of 18-17 after an emotional debate.

I don't think I understand all of this... I do know that it being introduced by a repug it is almost certainly complete shit.
