Voters passed Amendment 64 in 2012, which led to the legalization of marijuana in Colorado. In 2013, 10 percent of the drivers in fatality accidents tested positive for the drug. By 2016, the state experienced a 145 percent increase in fatal traffic accidents.

Drunk drivers still kill more people than those who are high, but the marijuana being sold legally has increased in potency and is readily available. A 9news report said 1/3 of teens don’t know it’s illegal to drive while high, and many adults don’t fare much better.

Testing for marijuana is sketchy as trace amounts of THC can be in the bloodstream from weeks earlier and blood tests at a hospital are time-consuming, expensive and impractical.

“Nobody understands it and people are dying. That’s a huge public safety problem.”

Be extra alert next time you roll south of the border.
