In Colorado, a look at life after marijuana legalization

The illegality of the stubstance gave police an excuse to search the car, or to intimidate the driver into implicitly consenting to a search of the car, during which they inevitably find something the stoner or one of their friends forgot which leads to an arrest. I've seen it play out on COPS dozens of times.

I wonder why they don't go back to doing a sobriety test for detecting intoxication though. It worked ok before breathalyzers, if you can pass the test than presumably you are ok to drive.

One study found a field sobriety test to correctly classify impaired driving state due to THC 65-75% of the time [1]. The chance of a false positive seems too high to me given the harsh penalty of a DUI. Field sobriety tests have been shown to be ~91-94% reliable for alcohol impairment [2].
