Over 40% of deceased drivers in vehicle crashes test positive for THC: Study(www.facs.org)

My question is, what is the difference in vehicle death mortality since cannabis was legalized in those parts of the country. If it's about the same, it just tells me that cannabis is a very popular drug.

From what I understand, the effect of legalization (or decriminalization) on the amount of cannabis use is not straightforward at all. You'd have to factor that in somehow.

You wouldn't expect sober people to be more likely to die.

I remember reading that in an accident with one party intoxicated and the other not, the intoxicated party is more likely to survive because they are more relaxed and can take an impact better. But of course sober people are less likely to get into single car fatality causing accidents I'm sure.

The lack of change after legalization of recreational use is interesting. How many deaths related to medical use versus (previously illegal but decriminalized) recreational use?

I don't think the user population changes much whether it's illegal, "medical," or legal.

This feels like we’re missing a dimension or threeve, the one that comes to mind immediately would be whether or not the deceased driver was at fault for the incident.

Yeah, drug use is also influenced by social and economic status, which also influences driving risks. People of lower socioeconomic status drive less safe cars on less safe roads for longer commutes. This is something valid to evaluate with a drug like THC which is detectable long after use. It would be nice to see the distribution of levels detected and not just the average.

But can't you account for 'type of car', 'type of road', 'commute length' as direct variables pretty easily without dipping into social/economic backgrounds?

The socioeconomics of the situation is why I'm questioning it, not what I think would be best measured.

Although it certainly isn't "easy" to measure all of this directly; there are thousands of that constitute the type of driving scenario that someone might engage in. Even just "type of road" isn't a single thing, it's hundreds of things.

Don't be so judgemental, dying is traumatic! Who wouldn't want a little somethin' to take the edge off?

I’m not surprised so many deceased drivers were under the influence of THC. I see people smoking and vaping at stoplights all the time. I am however, surprised this study claims legalization didn’t change the rate. Anecdotally, on the west coast, I’ve seen far more of this, and also people casually smoking in public spaces (parks or train stations or whatever) since legalization.

Obviously the study is not claiming that rates of THC use in general remain the same.

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.

Are they necessarily smoking and vaping cannabis though? My vape is visually pretty similar to a tobacco vape, and vaping doesn't usually have much odor either way (unless it's scented vape juice, but I'm not terribly worried about cognitive impairment from bubble gum).
SilverElfin 3 days ago||
As far as my experience goes, yes. I can tell by the scent. And actually at stoplights I can smell it even with windows rolled up.

Just that you see it more doesn't necessarily mean it happens more

That could mean that THC is not causative, just coincidence.

I need to know the rates in the general driving population before I can assume driving high is dangerous.
