It's not a problem, it's a business opportunity. Imagine being a sole manufacturer of a device every cop will be carrying... Many successful companies are making human lives miserable anyway, this is simply one more.

The science is actually pretty concrete regarding the impairing effects of THC. Because cannabis is a schedule 1 drug, it can be very difficult for researchers to get their hands on real world doses of THC. Instead, they use very low doses that are not relevant to what is actually sold at dispensaries. For a really good review of all things cannabis impairment, I would recommend looking through the following report by the Cannabis Control Commission in Massachusetts. A little long, but a lot of good information. https://mass-cannabis-control.com/wp-content/uploads/2019/01...

You claim that the science is concrete but cite no actual studies. I’m assuming that this kind of behavior is going to be a good indicator of the product’s actual effectiveness on driving safety overall.

I'm shocked that an organization called the Cannabis Control Commission published a report in favor of Cannabis Control!

I urge you to read the report. I think it relays a very balanced accounting of the facts. Its also a good place to find all the studies in one document, so I don't have to send you 100 links!

I spent several minutes looking and was not able to find those links within the 223 page report.

What do you think about the National Highway Traffic Safety Administration report to Congress? https://www.nhtsa.gov/sites/nhtsa.dot.gov/files/documents/81...

It seems pretty clear in terms of the art of the science and the impairment observed from actual national data.
