WICHITA, Kan. (KWCH) - On Friday, Kansas law enforcement officers take to the road, making sure you’re not driving high during “420″ weekend.

The Kansas Department of Transportation said it consistently sees drug-related crashes increase on the April 20 weekend. So the Kansas Highway Patrol has ramped up enforcement across the state with drug checkpoints.

Recent technology has made it even easier for law enforcement in Kansas to detect people who are driving high. Kansas has invested in roadside fluid instruments. Now, oral tests are given to people who are suspected of driving under the influence, and within a few minutes, every substance in your system will pop up. Law enforcement can then charge you accordingly.

“When a person consumes a drug, it’s going to pass through their blood into their oral fluid, and it will be detected by oral fluid testing. It’s a good indicator of recent use or that they’ve consumed rather recently, leading up to or when they were driving,” KHP DUI Division Lt. Sean Hankins said.

Oral testing can determine if you’ve ingested drugs like cannabis, methamphetamines, cocaine, mood stabilizers and some opiates.

Gary Herman is the behavioral safety manager at KDOT. He said a common myth is that people drive slower when they’re high.

“All the scientific research shows impairment is impairment no matter what the substance is,” Herman said. “They’ve actually scientifically studied that and found out that people who are high on marijuana drive faster. The exact opposite of what the myth is, is true. It doesn’t make you a safer driver.”

A reminder -- it’s illegal to possess or purchase marijuana anywhere in Kansas, even if you purchase it legally in another state.

Herman said a DUI conviction can cost you up to $10,000 after legal fees and paying for an ignition interlock device (IID).

“Kansas is one of the states that requires IIDs on your first DUI conviction. if you get convicted, you’re going to be looking at the installation costs, the monthly monitoring costs of that IID. There’s a lot of costs that people forget when they look at how it might affect them if they get caught.”

KHP emphasized that this weekend’s enforcement is the same as any other weekend in the fact that law enforcement always is on the lookout for any type of impairment on Kansas roads and highways.
