Since Marijuana Legalization, Highway Fatalities In Colorado Are At Near-Historic Lows

COLORADO:  Since Colorado voters legalized pot in 2012, prohibition supporters have warned that recreational marijuana will lead to a scourge of “drugged divers” on the state’s roads. They often point out that when the state legalized medical marijuana in 2001, there was a surge in drivers found to have smoked pot. They also point to studies showing that in other states that have legalized pot for medical purposes, we’ve seen an increase in the number of drivers testing positive for the drug who were involved in fatal car accidents. The anti-pot group SAM recently pointed out that even before the first legal pot store opened in Washington state, the number of drivers in that state testing positive for pot jumped by a third.

The problem with these criticisms is that we can test only for the presence of marijuana metabolites, not for inebriation. Metabolites can linger in the body for days after the drug’s effects wear off — sometimes even for weeks. Because we all metabolize drugs differently (and at different times and under different conditions), all that a positive test tells us is that the driver has smoked pot at some point in the past few days or weeks.

It makes sense that loosening restrictions on pot would result in a higher percentage of drivers involved in fatal traffic accidents having smoked the drug at some point over the past few days or weeks. You’d also expect to find that a higher percentage of churchgoers, good Samaritans and soup kitchen volunteers would have pot in their system. You’d expect a similar result among any large sampling of people. This doesn’t necessarily mean that marijuana caused or was even a contributing factor to accidents, traffic violations or fatalities.

This isn’t an argument that pot wasn’t a factor in at least some of those accidents, either. But that’s precisely the point. A post-accident test for marijuana metabolites doesn’t tell us much at all about whether pot contributed to the accident.

 

More Drivers Positive For Pot In Washington

WASHINGTON: More drivers tested positive for marijuana in Washington in 2013 — the first full year after the state legalized pot — but officials so far say there’s been no obvious, corresponding jump in car accidents.

The Washington State Patrol says 1,362 drivers tested positive for having active marijuana in their system — a jump of just under 25 percent from the year before, even though the patrol had fewer troopers on the road and there was no overall rise in intoxicated driving arrests.

Of those, 720 had levels high enough to lead to an automatic drugged-driving conviction under the state’s legal pot law.

Nevertheless, a preliminary tally counts 99,690 crashes reported to law enforcement in 2013, an increase of just 72 from the year before, State Patrol spokesman Bob Calkins said. Of those, 443 were fatal — compared to 444 in 2012, 454 in 2011 and 521 in 2008.

 

Washington State Patrol Stepping Up Patrols For Drivers High On Pot

WASHINGTON: The Washington State Patrol is requiring troopers to complete training in “Advanced Roadside Impaired Driving Enforcement.” The training is part of a course to help troopers spot people driving while high on marijuana.

In Washington, driving under the influence is no longer just about alcohol. The legalization of marijuana has added a new dimension to patrols.

Troopers use a 5 nano-gram basis, much like the .08 level for alcohol, to determine if a person is driving while high on pot. [Read more…]
