I disagree wholeheartedly, but even if I agreed with you that doesn't mean that this breathalyzer is a good solution:

To the points about people passing out or cops calling 911 on themselves that speaks to the incredible variety of experience people have and what someone might experience their first time with edibles. It's not comparable to the effects smoking has on regular users, and not something anyone should be doing while driving, but how do you test for that with a Breathalyzer?

Fair points but I think this testing is only about smoking? That would seem to give even less reason to support this kind of testing since it misses the most egregious cases of edibles. I think anyone would agree that people in that kind of state are in no condition to drive, but again in my experience way outside of normal usage and not something I have ever seen. If the test took that into account alright, but it seems like these breathalyzer would be detecting a far lower threshold

Edit: "Theyre working on it" when it comes to edibles....

I don't see how the argument is much different than for someone having some beers? If they have a few beers daily and blow over is this fair as it likely is not impairing them due to a higher tolerance? How is this different than if a regular weed user were to blow over, but also may have a higher tolerance?

The problem is that you can't really test for these tolerances, especially not in the field. That's why it's usually better to air on the side of caution and set a limit.
