Is Marijuana Legalization Causing More Car Accidents in Denver, Colorado?

Let’s just say it’s complicated. Here’s what Colorado car accident statistics show.

According to the Colorado Department of Transportation (CDOT) data, here is how fatal traffic accidents in Colorado have trended since 2002.

After a high of 677 fatal crashes in 2002, deadly automotive accidents began to decline overall for more than a decade. This reduction in traffic deaths trended in the right direction until 2014 when fatal car accidents in Colorado began rising sharply once again.

Some observers have been quick to point out that January 1, 2014, was the landmark date when recreational marijuana use became legal in Colorado.

So, when fatal car accidents in 2017 once again climbed over 600 for the first time since 2002, the question was asked: could the two be correlated? Unfortunately, there’s no clear answer. While the number of deaths involving Colorado drivers with marijuana in their system grew in 2017, cause and effect are not that simple in these cases. THC, the main psychoactive compound in marijuana, can stay in the human body for up to 45 days. This means a driver who tests positive for having marijuana in their system was not necessarily driving impaired.

In other words, the number of drivers testing positive for marijuana isn’t necessarily the best indicator of whether legalized marijuana is causing more car accidents in Colorado. Additionally, medical marijuana had been legalized years prior during a decrease in serious car accidents and driving injuries. Instead, we need to get a more complete look at the numbers.

What is the Legal Limit for Driving High on Marijuana in Colorado?

0.08 is the famous BAC (blood alcohol content) level that legally determines whether someone is driving under the influence of alcohol. But how do you know if someone is driving under the influence of marijuana? Colorado law specifies that drivers with five nanograms of active THC in their whole blood can be prosecuted for driving under the influence (DUI). And according to CDOT accident data, traffic fatalities in which drivers had enough marijuana in their bloodstream to be deemed legally impaired dropped sharply from 2016 to 2017 (from 52 to 35, respectively).

This may seem like a contradiction, but, remember, these numbers only pertain to fatal accidents. There are thousands of accidents outside of the ones that end fatally. Even if a car accident is not fatal, it can cause severe injuries. If you are injured in an auto accident, you can be looking at broken bones, severe brain trauma, and physical disability. Recovering from a non-fatal car accident can still take years of rehabilitation or physical therapy.

If you are injured in an auto accident that you suspect may have been caused by marijuana, then it is important to have an experienced attorney on your side. Insurance companies are still figuring out how marijuana influences their insurance claims, and you won’t want to see an auto accident claim denied. Make sure that you have a Colorado attorney like McDivitt to help get the settlement that you deserve.

Marijuana’s Effect on Driving

When Colorado legalized recreational marijuana, safety experts wondered how this would affect the number of car accidents and pedestrian collisions across the state. And for good reason. Studies have shown:

  • Drivers under the influence of marijuana weave more in simulated traffic studies.
  • Drivers under the influence of marijuana have slower thinking and perceptual skills.
  • According to the National Institute on Drug Abuse, marijuana “significantly impairs judgment, motor coordination, and reaction time.”

This may be why car accidents in states that have legalized marijuana are increasing according to some reports. Research from the Insurance Institute for Highway Safety (IIHS) and Highway Loss Data Institute (HLDI) reveals that car accidents are up by as much as 6 percent in Colorado, Nevada, Oregon and Washington (all states that have legalized recreational marijuana) compared to neighboring states that haven’t legalized the drug.

What to Do if You’re Concerned About Marijuana’s Impact on Colorado Drivers

In the grand scheme of things, legalized marijuana is still very new to Colorado. More research and data will be needed before we can begin reaching definitive conclusions. In the meantime, regardless of how you feel, there are ways to have your voice heard. In 2018, CDOT introduced “The Cannabis Conversation” – a statewide traffic safety campaign aimed to engage Coloradans in a meaningful discussion about marijuana and driving.
