I would expect there to be significant overlap between the demographics of those who more commonly get in accidents and those who use THC. Based on nsc.org, it seems like the majority of car accidents are with drivers 25-34 years old, and occur more frequently late at night on weekends. That generally matches the profile of the stereotypical THC user. It is hard to find good numbers of THC use.

Remember that not all the population drives, nor are accidents randomly distributed in the population.

So in other words, people with a less risk-averse personality are more likely to engage in risky behaviors

”That generally matches the profile of the stereotypical THC user”

Got a source for that claim?
