A city in Illinois is working with a roadside test to determine if a driver is impaired by marijuana.

January 1st, 2020 is rapidly approaching. There are still many things to figure out before legal recreational marijuana kicks off in the Land of Lincoln.

Authorities have several concerns especially when it comes to driving under the influence of weed. They want a solution to that problem. Unfortunately, there doesn't seem to be a simple answer.

According to dailyherald.com,

"Carol Stream police are leading the way with their second saliva pilot program. But law enforcement and medical experts caution there is no real consensus about determining impairment via chemical testing and observation of drivers' behavior remains crucial."

"Illinois law says drivers are impaired when they have 10 nanograms of THC per milliliter of saliva or other bodily fluid or 5 nanograms per milliliter of blood."

"There can be differences in how people react to marijuana, depending on factors such as its strength, whether people are novices or habitual users, and whether they also drank alcohol or took prescription drugs. People that have been over 50 nanograms that aren't showing signs of impairment, and people that have been at 5 nanograms and can't stand up." 

If you plan on partaking, this is something you might want to keep an eye on. Though, at this point, it seems like they've got a long way to go for a solution.
