We can control for less people on the road by looking at stats per-million km driven. And again, we're not seeing any meaningful movement.

And to the points around "maybe the true cases of people above the limit were EVEN HIGHER due to fear of testing around Covid" or "Maybe the actual THC content was EVEN HIGHER because of the time delay" they both actually drive to the same point:

If we're seeing way more people with THC in their system maybe more than we even know, and at levels of concentration higher than we can even test... Then why aren't we seeing significant increases in accidents or fatalities per million kms? We CLEARLY see these patterns w/ alcohol. Why not THC? Why the disconnect?

If anything, your arguments only make me think that THC levels that we're seeing are safer than previously understood w.r.t operating a motor vehicle.

Keep in mind, I'm not suggesting relaxing them. I'm just pointing out that the "skyrocketing" THC DUIs aren't materializing.

Or at least I'm not seeing them in the data in front of me

Also, full disclosure, I am not a smart man

If I'm missing a link or misreading something somewhere, let me know. I'm not married to my evaluation. I'm just trying to come to the same conclusion about safety as you and can't seem to independently get there.
