I think it's generally accepted that cannabis intoxication can't be measured by a breathalyzer in the same way alcohol intoxication can. Rather than saying "x" amount of THC on the breath means you're high, a weed breathalyzer is going to detect recency of use (hours rather than days like with spit or urine). There isn't even an agreed upon THC-blood level for intoxication. Some jurisdictions say 5 ng/ml, but that number is arbitrary and meaningless.
As to Dr Hill - The Mas Spectrometer for Chemring which looks for Explosives which Our Dr Yost and Our Dr Boock and Dr Hill built for them, Chemring provided $250,000 to build their FAIMS THC Breathalyzer, the Washington University I mean, which 1st Links quotes - To much cost to go further on building - Never said it didn't work but the cost would be to High
Love it as there is no-other Competition now
We're 95% there already and posted in November 5th Report
All those things needed to be Court Certified are 95% done here and Dr Hill doesn't have the Funds to shrink all that and BLO/ZF is 95% there
Control Chamber offering a Controlled Temp and Controlled Moister content - Be it raining out or on the North Pole verse sitting in Florida Keys, then there's the creation of the Power Supply - We have here a Square Wave Generation that run off rechargeable batteries, (which I'll say is about the toughest part of the process, constantly getting the same charge between Units - All got to be the same to get true readings) - - Then you get into a Captured Sample for running threw a Mass Spectrometer which will be Jail House Model and probably Calibrate the Hand Held FAIMS Units which we have already built a In-house Bench Top Model (BETA 1.0), I know I'm missing something like the Mouth Piece and others stuff but Cannabix Claims 95% done and the only competitor was the Chemring Group (WSU) and now WSU claim's it would cost to much
Even if the Unit cost $5K which BLO/ZF claims $2K/$3K
Who cares because the Marijuana Industry will pay for it (At least the States that have Marijuana Legal)
Watch this push other States to Legalizing Marijuana
