Three drivers of varying ages got incredibly high on marijuana and test-drove cars around a course. A driving-ed instructor accompanied them to avert any chance of an accident, and police watched from the sidelines to spot any visible ‘signs’ of inebriation in their movements.
The volunteers — a young daily smoker, adult weekend smoker and elder infrequent smoker — proceeded to test escalating levels of stupor against the new baseline ‘legal limits’ in Colorado and Washington state.
Well at a certain point, the substance had an undeniable effect on their ability to navigate a vehicle sensibly. But they all maintained surprising control, even at incredibly excessive levels of marijuana consumption. Moreover, unlike drunk drivers, they were very much aware of their state and agreed they were not on top of their game. Without over-indulging, it seems people’s critical thinking can be trusted more with a few hits than a couple of drinks.
