Thanks for your reply and engaging in this sort of discourse. I agree with all of your points, and also feel that technology in this area can help in conjunction with other indicators and tests to determine dangerously impaired driving. Any improvement over the existing testing methodology and legislation where some blood concentration possibly present from the week prior serves as enough for a felony conviction seems well warranted!

Cannabis has been medically prescribed in CO for nearly 20 years. As of this year, autism spectrum disorders are a disabling medical condition qualifying for medical use, joining PTSD, seizures, cancer, glaucoma, AIDS, severe pain, and others.

https://www.cell.com/pb-assets/journals/trends/molecular-med... draws similar conclusions scientifically rather than anecdotally -

"Currently, science does not support the development of cannabinoid limits in motor vehicles drivers per se because of the many factors influencing concentration–effect relation-ships."

"There is no one blood or oral fluid concentration that can differentiate impaired and not impaired."

I've been a daily cannabis user for over a decade. I have a prescription for this, like millions of others with prescriptions for psychoactive medications without driving limitations. Would you send someone to prison for driving because they took their Adderall that morning? Cannabis is not like alcohol in regard to impairment of motor function and decision-making under the influence. Surely the same concentrations of particulate correlate to different levels of impairment in different individuals. Of course it is possible for individuals to be impaired by cannabis to the extent that driving would be dangerous. There are many factors. I'm wary of a device that purports to determine actions as dangerous based on the the measure of some particulate in the breath.
