Colorado has a drugged driving problem.
Lukas Myers knows this. The photo shows him being extracted from a car when he was 12 years old after a crash caused by a marijuana-impaired driver. Most bones in both of Lukas’s legs were broken as well as both wrists.
For some, stories like this are convincing. Others need data. So here is a summary of relevant data from 10 sources.
|Methamphetamine and similar||1,090|
Note: CBI data from Jul 2019 to Jun 2020 when all DUI blood samples were tested for both alcohol and a full drug panel.
Note: the above reports measured the effect of marijuana commercialization in 2014, not marijuana legalization in 2012.
There were 632 traffic fatalities in 2018. 87% of the drivers in those fatal crashes were tested for drugs. 83 tested positive for THC including 36 at or above 5 ng/ml.
|Single other drug only||1|
|Alcohol + THC||2|
|Alcohol + other drug||1|
|Alcohol + THC + other drug||2|
So what is Colorado doing about the problem?
Deny the problem exists
In 2020 the Department of Motor Vehicles revised the Driver Handbook to say, “…it is unclear whether cannabis use increases the risk of car crashes.”
Encourage marijuana use
During the COVID pandemic shutdown, marijuana dealers were classified as an “essential business” by the Governor, permitting them to sell their product while non-essential businesses were required to close.
Home delivery of marijuana was authorized, ostensibly to reduce drugged driving.
At the December 14, 2020 meeting of the Retail Marijuana Public Health Advisory Committee, the Colorado Department of Public Health an Environment announced that henceforth, “marijuana users” were to be referred to as “cannabis consumers” since the former label is pejorative. You just can’t make this stuff up.
Subsidize the marijuana industry
Governor Polis announced a $584,399 tax credit to Canadian marijuana company SLANG Worldwide to expand operations in Colorado.
On a side note that may not be completely unrelated, Governor Polis is rated A+ by NORML, the National Organization to Reform Marijuana Laws.

Colorado authorized the use of marijuana tax dollars to temporarily fund a program at the Colorado Bureau of Investigation’s Forensic Toxicology laboratory, enabling them to test all DUI toxicology samples for drugs as well as alcohol. The laboratory issued summary results June 30, 2020 after completing the first year of this program. CBI performs about half of all the DUI lab tests in the state.
For the last year, stoned driving topped drunk driving, something we’ve never had the data to prove before. There were 12,771 positive results for drugs and alcohol from the 9,763 sample submissions, an indication of the prevalence of polydrug impairment.
Highlights of the report include:
THC positive cases 4,069, 51% of which were below 5 ng/ml
Alcohol positive cases 3,956
Benzodiazepines 1,774, 12.8% of which were designer drugs
Methamphetamine family 1,090

One study found an excess 75 traffic deaths per year after retail sales began in Colorado in January 2014, compared with states without similar laws. But it found no similar change in Washington state.
The other study looked at those states plus two others that allow recreational pot sales, Oregon and Alaska. If every state legalized recreational marijuana sales, an extra 6,800 people would die each year in traffic accidents, the researchers calculated. They found an increase of 2 deaths per billion miles traveled compared with 20 states without those laws. That change was slightly higher than in the other study.
Recreational cannabis use affects driving ability even when drivers are not intoxicated by marijuana, according to a study from a Harvard Medical School hospital.
Published in the Drug and Alcohol Dependence journal, the study “Recreational Cannabis Use Impairs Driving Performance in the Absence of Acute Intoxication,” finds that in addition to chronic, heavy, recreational cannabis use being associated with poorer driving performance in non-intoxicated individuals compared to non-users, the researchers linked earlier onset of marijuana use (under age 16) to worse performance.
The study was conducted by McLean Hospital’s Mary Kathryn Dahlgren, PhD, Staci Gruber, PhD, and their team from McLean’s Cognitive and Clinical Neuroimaging Core and the Marijuana Investigations for Neuroscientific Discovery (MIND) program. The study, conducted through driving simulation, concluded that chronic, heavy, recreational marijuana use was associated with worse driving performance in non-intoxicated drivers compared to non-using healthy control participants.
Other findings of the study:
Many American’s lose their lives each year due to impaired driving. Traffic fatalities are rising in states which have legalized marijuana. We believe this emerging danger needs to be dealt with–the public needs to be forewarned, and politicians need to consider this issue when accepting campaign contributions from the marijuana industry.
Since recreational marijuana was legalized, traffic deaths in which drivers tested positive
for marijuana increased 109 percent while all Colorado traffic deaths increased 31
• Since recreational marijuana was legalized, traffic deaths involving drivers who tested
positive for marijuana more than doubled from 55 in 2013 to 115 people killed in 2018.
o This equates to one person killed every 3 days in 2018 compared to one person
killed every 6 ½ days in 2013.
• Since recreational marijuana was legalized, the percentage of all Colorado traffic deaths
that were marijuana related increased from 15 percent in 2013 to 23 percent in 2018.

Mothers Against Drunk Driving (MADD) helped wake up the country to the dangers of drunk driving. They succeeded in getting laws changed, nationwide in the United States. Now that four more states have legalized marijuana, what about stoned or high driving? Driving under the influence of a drug (DUID), is this something to be concerned about or, is it, as many stoners believe, people drive better while impaired?
On March 29, 2017, about 12:20 p.m., a fatal traffic collision occurred on US Highway 83 near Concan, Texas. The crash involved a 2007 Dodge Ram pickup truck traveling north on US 83 which crossed the centerline of the rural highway and collided with a medium-size bus. As a result of the crash, the bus driver and 12 passengers were fatally injured. The driver of the truck and one bus passenger sustained serious injuries. The video includes clips of a recording made by a witness in a vehicle following the pickup truck. The original video was recorded using a Samsung Galaxy S5 cell phone camera and was 14 minutes and 27 seconds in length. The video ended about 20 seconds prior to the crash. The video clips shown include a time stamp depicting the elapsed time relative to the beginning of the recording. Image stabilization software was used to reduce the motion of the camera seen in the original recording. Audio recording of the two occupants in the witness vehicle was removed.

DENVER (CBS4)– For the first time, there’s hard evidence that more and more people are driving high in Colorado. And, the sobering statistics could impact the growing marijuana industry in our state.
While police have tracked DUIs for years, they’ve lumped them altogether, so there’s no telling which drugs are the biggest problems.
Ed Wood helped changed that with a law that requires DUI data specify the drug involved. Wood’s son Brian was killed by two women sharing the wheel of car while high. Devastated, he dedicated his life to getting marijuana impaired drivers off the road.
“There’s a large gap between actual and perceived risk imposed by THC-impaired drivers,” said Wood.
While alcohol is still the drug of choice, the Colorado Bureau of Investigation says 47% of drivers are testing positive for marijuana, followed by amphetamines and cocaine. The Colorado State Patrol says DUI arrests involving marijuana are up 48% in the last year.
“We need to do for drug impairment what we’ve already done for alcohol impairment,” said Wood.
That starts, he says, with changing the Department of Motor Vehicle Driver Handbook which states, “It is unclear whether cannabis use increases the risk of car crashes.”
According to the Colorado Department of Transportation, the number of marijuana impaired drivers involved in deadly crashes has risen every year between 2017 and 2019, the most recent years for which data is available.
Wood knows that any change won’t be easy. He’s been at it 10 years.
“There are times I give up and say, ‘I’m not doing this anymore.’”
