Impairment is somewhat orthogonal to drug or alcohol intoxication. It's not safe to drive if you've been awake for 24+ hours, for example, or have some other medical condition (hypoglycemia, whatever) that impairs your ability to drive safely.

This has nothing to do with "intoxication" or sleep deprivation, or medical conditions. Some police will lie and charge people with "DUI" when there is zero justification, and they ruin lives because too many of them are sadistic assholes. It's in epidemic in Tennessee and other parts of the country, but it really could happen anywhere to anyone. Police unions are a problem, and taxpayers pay for the litigation when…

One useful point of comparison here would be the percent of the driving population overall who have some THC in their system in the same way as these researchers are measuring it. I wouldn’t guess that 40% of drivers would test positive for recent THC use, but I can’t understand the 40% number here without knowing the percent for the overall population.

The number of people who use any THC at all isn’t even close to 40% thought. The highest survey numbers I found had 20% of people reporting any use, even once, in the past year. There’s no way to normalize a result of 40% of a population sample having significant THC concentrations. That’s way higher than any conceivable sample of the general population.

But the truth is that habitual users are always impaired. Source: former habitual user.

Got any real sources? I've been a daily user for over 10 years and also have a spotless driving record.

Yeah I feel like the United States could dramatically improve its road safety if it kept maybe 1-3% of its drivers off the road permanently.

the problem is that our urban planning is so F@#$ed that taking away someone's ability to drive is tantamount to sentencing someone to poverty. In most of the country, you are completely dependent on a car to hold down a job, get groceries and pretty much anything else. In most other countries, not having a car is a mild to moderate inconvenience you can work around.

If the population of dead drivers with over the limit THC is 40%, and this dramatically exceeds the population average, that would strongly suggest the THC level IS an indicator of either: 1. Impairment from THC, or 2. Worse than average driving and risk management skills in those who use the drug

It's seat belts. People who die in wrecks are overwhelmingly not wearing seat belts. I would think marijuana users as a group probably have average seat belt usage, but people who don't wear seat belts probably have much higher than average marijuanna usage. Roughy 92% of people wear seat belts. But that 8% of people that don't wear setbelts makes up 50% or more of all fatalities. From my personal experience it seems…
