"Police in Colorado say the driver of the car had marijuana in his system."

That's a pretty meaningless statement in and of itself. Marijuana can remain in your "system" weeks or even months after any psychoactive effect has disappeared. THC is fat soluble.

From another article on the same subject.

Tests that detect marijuana's active ingredient, THC, don't always do so in a way that reflects whether a person is impaired, as traces of THC can remain in the system long after use and individual tolerance varies widely. But the group says it is reasonably certain to believe that marijuana has contributed to the causes of some crashes and increased the risk of driving for some motorists.

Then percent of drivers in CO say that being high makes them better drivers!

Yep. It’s a bit like saying “the money tested for traces of cocaine.” Pretty much all money not fresh out of the mint will test positive for cocaine residue.

i.e. meaningless.

Meaningless statement?

Tell that to Ron’s fiancé Barb.

Exactly. This is scare mongering, though it generally remains detectable for about a month.
