Stoners are easy to bust for impaired driving.

At least that that appears to be the consensus of Washington State law enforcement officials, who are now making it mandatory for their state troopers to complete an “Advanced Roadside Impaired Driving Enforcement” course, so that officers are able to spot the textbook habits of the high driver.

Washington State Patrol Sergeant Jason Hicks says that ever since marijuana achieved legal status in the state, officers have been forced to amend their methods for controlling impaired driving -- a task that is no longer just about looking out for drunkards.

“This became a law in Washington, we're going to monitor it, we're going to pay attention to it and if some adjustments need to be made in the way we do business, then we're going to make the adjustments,” he said.

Sergeant Hicks says that in the past six months, nearly 2,740 blood samples have been tested for marijuana impairment -- 745 tested positive. He says that his department expects the high driving trend with skyrocket by almost 33% this year.

However, Hicks says that catching stoners ripped behind the wheel is a relatively simple task because all of them make the same simple mistakes, adding that stoners cannot seem to multi-task.

“First, a person driving high is going the speed limit, but weaving in and out of traffic or failing to use their turn signals. And secondly, they're driving straight as an arrow and they're either above the speed limit significantly or below the speed limit significantly, because they cannot look at the speedometer and make sure they drive straight at the same time,” he said.

Hicks says that while there is no marijuana breathalyzer, his troopers can almost always spot a stoner, mostly because their eyes are watery and bloodshot.

And while we certainly do not advocate for driving high, we might suggest investing in a bottle eye drops just to give those of you that must a fighting chance.
