Just click the belt in with no one occupying the seat and sit on top of it.

I never understood this though. It seems like more work and even more uncomfortable just to knowingly make things worse for yourself.

Either O B E Y or do what you named as "more work". Different person chooses different way of dealing with annoyances.

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…

How are people not wearing seatbelt? I've never seen a car that doesn't make a constant annoying noise if you're not wearing it while driving. Do they mod the car to disable this safety system? That seems too far stretched...

As a reminder of how little things change. I remember watching an old video from sometime when seatbelt laws were mandated in Texas.

People were rambling on about how they basically live in the Soviet Union.

This seems like an intentionally misleading title, since they don't mention that the study was for one county (Montgomery County) in Ohio, which is basically just Dayton, OH and surrounding rural area - I'm sure you can pick other counties in the US which have either very high representation of THC users or very low representations. Without knowing how other counties score in terms of driver fatalities and THC, this…

> I'm skeptical that the alcohol industry might be involved.

So you don't think that the alcohol industry is involved?

Some helpful context: The number of Americans age 12 and older who report using any marijuana product at least once in the past year is around 20% (Source https://apnews.com/article/marijuana-cannabis-alcohol-use-di... ) if I use one of the highest reported use numbers I can find. Even if you dismiss all of the questions brought up in these comments like the use of mean levels instead of median, not accounting for to…

The biggest problem with drawing conclusions from the 40% number is that THC use correlates with other well established crash death risks like being a young driver or the use of other impairing substances.

The fact that legalization did not impact the crash rates is also a strong signal that THC itself is not causing the crashes.

The presence of THC in the blood is not a reliable signal for intoxication, so further research is needed to draw any type of conclusion.

Finally, it's also been noted that there are some sample bias concerns because the data comes from fatal crashes where it was determined that a drug test should be administered after the crash.

The problem is how do you enforce that though. The modern world is so cat centric people would rather drive without a license than accept to live without a car. And until you can reliably catch and jail license-less drivers, the bet is worth it for them.

If they were to catch and jail just 1% of license-less drivers, in a visible way, it would be a deterrent to the other 99%. But the rate of being caught & punished is negligible (at least in the states I've lived in) so people know they'll get away with it. I previously lived in a country where the cops set up random roadblocks to check everyone's license & registration and look for signs of intoxication. When there'…

1% is actually negligible, and would not have a deterrent effect. In fact I wouldn't even be surprised if the effective prosecution rate was somewhat higher than this already.

> I previously lived in a country where the cops set up random roadblocks to check everyone's license & registration and look for signs of intoxication.

I live in a country (France) where this is still the case, and where driving crimes are the second source of jail time after drug trafficking, yet alcohol is still the #1 cause of death on the road, and an estimate 2% of people drive without a license after having lost it (and are responsible for ~5% of accidents).

To give some statistical context, as of 2023, about 16.11% of people in the US have used cannabis in the past year; per that same dataset, about 16.53% of Ohio residents. [1] Given that Ohio’s usage metrics align closely with the national mean, I think it's fair to use the state as a proxy for broader domestic trends. Per more Pew Research data, also from 2023, Ohio seems to have an average, if not a less than averag…

You cannot pick and choose one or two variables and then claim representativeness based on a numerical match. The first step is to identify the confounding variables that are likely to influence the outcome. Only after those are specified a comparison set can be defined and matching or adjustment criteria applied. Without that process, agreement on a small number of aggregate measures does not establish that the underlying populations or mechanisms are comparable.

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.

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

Sure, but the problem isn’t whether or not a driver is impaired, but the degree to which they are impaired.

Well, it would be good for the rest of us on the road if people driving two tons of murder box are 0% impaired. I'm no angel but I have gotten more diligent... I'm just reacting to "the degree". The goal has to be zero degrees of impairment when a moment of inattention can kill. Also, my son was just hit by a driver while he was on a bike and in the bike lane. They claimed not to see him. He's fine thankfully but it'…

0% impaired? We know tired drivers are impaired. Should we require drivers to demonstrate 8hrs of sleep before operating a vehicle? What about people who do ok on less sleep? I think there are obvious issues with such a proposal and those issues transfer to THC usage. I would bet, if we could measure it, a large portion of fatal accidents would involve people who are not fully rested and had missed the 8hr target multiple times in the preceding week or two
