I've tried asking this question on a different forum with no REAL answer. Does ANYONE know if the HGR drug test kit is being used by some authority out in the real world and if it ACTUALLY IS, where this might be???
Here in Qld, they have just introduced, roadside drug testing. I have read in the paper that these saliva tests cost around $40 per unit. I have been told on another forum that the HGR unit is around a quarter of that. I am more then curious as to why an Australian authority would NOT be using a product that is Oz made and significantly cheaper and supposedly better then what they have selected to use. Is the HGR unit available in Oz and if it is why would it not be used in this instance? Is it being used ANYWHERE else in the world??
I have searched everywhere for an answer but seem to only get speculation. Am I missing something?

I think it is a great product on paper, I am just concerned as to the lack of disclosure.

Would appreciate comments.
