Cannabis is now the third most commonly used substance in the United States, following nicotine and alcohol. This increase in usage correlates with its legalization in 38 states, with 24 allowing recreational use and 14 permitting medical use only. As a result, driving under the influence of cannabis has become more frequent, posing a higher risk of accidents and fatalities.
Dr. David Yang, president and executive director of the AAA Foundation for Traffic Safety, stated, "Understanding what motivates cannabis consumers to drive under the influence can be helpful in developing effective safety strategies." The AAA Foundation conducted two studies aimed at analyzing consumer perceptions and developing messages to deter this behavior.
One study involved surveys designed with input from experts across various fields. It found that daily or frequent cannabis consumption is common among users, with 44.1% consuming multiple times a day. Furthermore, 57.8% reported driving daily, and 84.8% admitted to driving on the same day they consumed cannabis. Notably, 46.9% believed their driving was unaffected or improved after consumption.
The second study focused on identifying effective messaging strategies for deterring impaired driving among regular cannabis users. Participants preferred messages emphasizing personal responsibility and safety over those highlighting legal risks. They also favored realistic and diverse messaging over exaggerated stereotypes.
Jake Nelson, AAA’s director of traffic safety advocacy, remarked on the need for credible voices in these campaigns: "Effective messaging about cannabis-impaired driving needs to include credible voices, real-world scenarios, and respectful language."
The research indicates that many consumers view the cannabis industry as a trustworthy source of information on safe driving practices. Policymakers have an opportunity to collaborate with industry groups to develop impactful messaging addressing impaired driving's dangers.
Despite challenges in detecting cannabis impairment compared to alcohol impairment, law enforcement continues efforts to identify it effectively. As cannabis use becomes more prevalent, public health messaging will play an essential role in improving road safety through policy implementation and education campaigns.
