No it wouldn't.
People make those excuses because it's weed, but you would have never posted that on an article about alcohol.
Well of course not, as the two drugs have completely different intoxication side effects.
Why did you automatically assume the point of bias?
A similar result about alcohol would be the (hypothetical) statement that the rate of drunk drivers in fatal accidents was constant before and after the enactment of Prohibition.
I do agree that the fact that fatal THC% stays constant before and after legalization is a surprise.
(Not that it really matters since I don't buy for a second that anywhere near 40% of people/people-driving are high at any given time. I also don't put much faith in numbers in the abstract of a a yet-to-be-published study...)
THC in the blood doesn’t mean actively high for habitual users, which would be most users if THC consumption is high. It means recent use, but not clear impairment.
If 40% of the whole population has THC in them, we'd need a control population (maybe from earlier when thc was less prominent) to see if per capita deaths has meaningfully increased. I'd do the same study, tangentially, for tech workers to see if productivity has changed when controlling for other variables.
If we are at 40% of the population being high at any given moment I think we are having extremely serious societal problems around mental health. Occasional use is not a big deal IMHO, but if a person is spending 40% of waking hours impaired that person has some serious unmet psychological needs.
I'm arguing that if the population data looks anything like the autopsy data, it would imply a massive epidemic of THC overuse.
That said, almost everyone I know that consumes THC has no qualms driving while doing it, and many of them also at work. It's a huge peeve of mine.
I wonder how many of these people were under the influence of alcohol and other substances.
That said, I don't do either. I also wouldn't take any amount of weed while working, but I'd feel comfortable having a beer during lunch if appropriate (work lunch/celebrate, e.g.).
Its not a sample, it is the whole universe of analysis. (If you treat it as a sample of, say, US drivers killed in accidents in the same period, then errors due to sample size are probably the least of its problems.)
> In a review of 246 deceased drivers, 41.9% tested positive for active THC in their blood, with an average level of 30.7 ng/mL — far exceeding most state impairment limits.
Since COVID in CA, it feels like driving has become far more dangerous with much more lawlessness regarding excessive speeding and running red lights, going into the left lane to turn right in front of stopped cars, all sorts of weird things. But I can't tell if my anecdotes are significant. It seems that Ohio's impaired drivers have been consistent through the past six years though.
NYC has had the same effect since COVID, and over the last year or two it's gotten to the point where every single light at every busy intersection in Manhattan you get 2-3 cars speeding through the red light right after it turns. I bike ride a lot so I'm looking around at drivers a lot, and for the most part the crazy drivers seem to be private citizens in personal cars, not Uber or commercial/industrial drivers.
To the OP, I'm not sure I buy into it being tied to THC which seems to be the implication. Canada isn't seeing this trend, afaik.
But the data here also show that it's a consistent level before and after legalization of cannabis in Ohio. So legalization of cannabis in Ohio did not cause a big increase in impairment-levels of THC in those who died in traffic.
They do not, though, give an owl's hoot about yielding to straight traffic when turning. I suspect NY drivers are on a big group chat encouraging each other to cut off cyclists and pedestrians, by turning into their lane whenever they see one, and promptly parking there for an hour.
And there's the "squeeze", and "crowding the box". Almost like no car here is truly allowed to ever really stop so they're always gently rolling, just a little, juuuuust a little, just, maybe, I know it's red but maybe just a lil squeeze into the intersection, maybe, squeeze, ...
I don't know how to explain it but if you've been here you'll recognize it I'm sure.
And not like running a late yellow, but a full on my-light-is-green-and-there's-a-guy-in-front-of-me-sideways
It has dropped a bit now though.
The trend I’ve noticed this year is turning right from the middle lane cutting off people in the turn lane.
Edit: no offense to Gen Z with my earlier comment btw. My reasoning was maybe we're failing younger generations with drivers ed so the blame would be on us anyway.
Also I've seen these strange patterns in many states in the last year+: Oregon, Washington, Wyoming, Idaho, California
I saw another one where the car tried to turn right into an off-ramp with a line of cars waiting at the light. Like wtf, do you not see the wall of cars and headlights in front of you? Where are you going?!

I remember the sad story of Michael Brown who was killed in 2014 while being arrested for selling loose cigarettes in Missouri. Today, at least in NYC, you see people parked out in front of the same corner every day selling weed and loose cigarettes. Same people, out in the open. I'm pretty sure that's not a sanctioned dispensary.
Just shows how much things can change in ten years. For whatever reason, police and prosecutors just gave up in enforcing any kind of laws. Seems like an overreaction to whatever problems we had with criminal justice

As far as driving goes, any amount of drugs or alchohol is going to reduce reactions times, in addition to any impaired judgement or ability to control the vehicle. Even a couple of 1/10ths of a second in increased reaction time is enough to make the difference between braking in time and hitting another car or pedestrian/etc.
We should not tolerate the ignorant and ineffectual response from lawmakers on this issue. Year after year, they refuse to do the right thing: make texting a DUI-level offense, with the same penalties. You could even argue that texting while driving is worse than DUI: Drunk people suffer from impaired judgment; sober people texting have decided to endanger and steal from everyone else while in full command of their faculties. It's despicable.

The other question I have - my prior is that a bad driver (tired, drunk, high) is something like 70:30 odds of killing themselves vs some innocent bystander dying because of their actions. I have anecdotally heard of several sad tales where some guy is on his Nth DUI and kills an entire family, while he walks away from the accident without a scratch. Meaning are the rates of fatalities involving THC actually higher, but the detectably inebriated person managed to walk away without dying.
The impairments of driving under the influence of alcohol have been extensively studied, but unless I have overlooked the literature it seems that the same investigations have not been carried out with THC.

For drunk drivers it’s rather easy to assess whether someone is impaired. With marijuana it’s not. So until we have a valid method of testing if someone is “too stoned to drive” we have to push back on any attempt to classify marijuana users as ineligible to drive.
You’re not really going to win anybody over to the legalization side when you basically say that people can consume as much THC as they want and drive without any penalties because of testing limitations.
> With marijuana it’s not. So until we have a valid method of testing if someone is “too stoned to drive” we have to push back on any attempt to classify marijuana users as ineligible to drive.
I agree. As someone who regularly consumes 250mg of edibles daily at a minimum, I’m sure my levels would be off the charts on a constant basis, even when sober. With the tolerance I currently have, it’d take a ridiculous amount to put me into a state where I felt driving wasn’t safe.
For example if we took random samples of the population and tested them for marijuana usage, what percentage would test positive?
Next, this study is only talking about marijuana testing, how many of the same group also tested positive for alcohol (or other impairing drugs). Lets make up fake numbers and say 60% of total fatalities had alcohol or other impairing drugs and the overlap between them and marijuana use was 80% then marijuana is rather insignificant.
We have to have all the details so we don't fall into a base rate fallacy.
50% of the people on this street get stoned before driving to work, every single day
dope isn't even legal here and even if it was DUI is wildly illegal
We can only cure this if we get serious about penalties because we can't undo murder and injuries
How about first time warning, second time weekend in jail, third time week in jail, fourth time month in jail, fifth time year in prison
Saying that in the country with world-leading mass incarceration mostly due to its decades long “war on drugs” which has very much not cured drug problems is a perfect example of putting ideological preconceptions ahead of reality.
I wish I could emphasize this even more.
There are some situations where certain types of punishments in certain situations will achieve societal behavior change.
There's a lot more where it doesn't and people absolutely to apply any kind of scientific thought to it.

One possible reason: the “new recruit” people who are now willing to use cannabis BECAUSE it is legal are also rule-following by being willing to stay off the road after using it. Perfectly plausible to me.
