As Cannabis Use Grows, So Does The Disconnect With Safe Driving
As cannabis use becomes more prevalent in the United States, the Governors Highway Safety Association (GHSA), Responsibility.org and the National Alliance to Stop Impaired Driving (NASID) released a new report that provides guidance on how State Highway Safety Offices (SHSOs) can better communicate with cannabis consumers about safe driving and offers recommendations about the types of messages that do and don’t work.
The report comes as SHSOs face a rapidly changing cannabis landscape that includes the legality, prevalence and social norms about its use. In 2011, no state had legalized recreational cannabis. Just 10 years later, 18 states have done so, and more states will have legalization on the ballot this November. Cannabis use has increased alongside the spread of state legalization. In 2019, 18% of people aged 12 and older in the U.S. reported using cannabis in the past year, up from 11% in 2002. Attitudes about cannabis use are changing, too. The drug is celebrated in places where it has traditionally been shunned. This year, two candidates for U.S. Senate have aired ads featuring them smoking cannabis.
Even as more people become familiar with cannabis and calls for national legalization grow, there remains a significant disconnect between people’s views on its use and safe driving, emphasizing the need for effective public outreach and education. An AAA Foundation for Traffic Safety survey found that 95% of people say driving while over the legal blood alcohol concentration (BAC) limit is very or extremely dangerous, but only 69% believe it is dangerous to drive within an hour of consuming cannabis. Some people even think that cannabis use improves their driving. But research confirms that cannabis directly affects the parts of the brain responsible for attention, decision-making, coordination, and reaction time, which are all critical for safe driving.
Compounding the challenges of addressing cannabis- and multiple substance-impaired driving, early signs point to cannabis playing an increasing role in traffic fatalities during the COVID-19 pandemic. Data from trauma centers indicated that 33% of drivers involved in fatal crashes had tetrahydrocannabinol (THC), the main psychoactive compound in cannabis, in their system – a significant increase from 21% before the pandemic. Cannabis was slightly more prevalent than alcohol in fatal crash-involved drivers (33% for cannabis vs. 29% for alcohol) during the pandemic. Impairment from multiple substances also rose the past few years, with 25% of drivers in fatal crashes testing positive for more than one impairing substance, compared to 18% before the pandemic.
“As legal cannabis use becomes more widespread in the U.S., motorists need to know the dangers of driving under the influence,” said GHSA Executive Director Jonathan Adkins. “But that message won’t be heard if it’s outdated, irrelevant or insulting to cannabis consumers. This new report offers a playbook to help states develop messaging that resonates with cannabis users and prompts them to refrain from driving for their own safety and the safety of everyone else on the road.”
“Impaired driving, whether it involves alcohol, cannabis, other drugs or a combination of substances, is wreaking havoc on our nation’s roads, and we all must respond quickly and effectively,” said Darrin Grondel, Ed.D., Vice President of Government Relations and Traffic Safety for Responsibility.org and Director of NASID. “The messages, strategies, data, and approaches identified in this new report will make that response more effective in positively changing cannabis consumer behavior to the benefit of every American on our nation’s roadways.”
