With Washington having recently become the first of two states to legalize the recreational use of marijuana, the local government has been tasked with determining how high a person can be before they are considered to be "driving under the influence."
To test how arbitrary the legal limit of 5 nanograms truly is, KIRO-TV, a Seattle-based CBS affiliate organized a driving test for stoners with the help of a local Sheriff's department, a drug recognition expert, and a driving school instructor.
Despite the fact that one of the volunteers was already three times over the legal limit before the start of the test — and all three volunteers were over four times the legal limit after their initial toke — they were still doing fine behind the wheel.
It was only after the subjects had smoked nearly a gram of pot that they were too stoned to drive.
Well, almost: Medical marijuana patient Addy Norton — the volunteer who was already buzzed going into the experiment — was "borderline" according to the officer observing the obstacle course.
Norton only became a hazard after inhaling another half a gram of pot — but by then even she knew she should not be on the road in her condition.
"(I'm) way more stoned. Way more stoned," she said. "Definitely shouldn't be driving."
