As a full supporter of cannabis legalization, I'm also a big supporter of a technology that can instantly detect whether someone's reflexes are impaired by cannabis.
Notice that I'm focusing on whether or not they are impaired, as opposed to the amount in their bloodstream. The point being that people that use cannabis regularly for medical reasons don't seem to be impaired by it at all, while newer or more occasional users are certainly impaired.
It would be fascinating to see what kind of technologies could be used to achieve this that folks on HN are aware of.
