Test Kit Cannabix is developing third party is your concentration level, Breathalyzer only needs to fail if you smoked last couple Hrs, the test kit for the station will be expensive, $25,000 is a guess and I might be off $25,000 but you can bet it's the heart of the Package, doesn't mean 100 breathalyzer at $1,500 ea is peanuts, total system probably $200,000 plus per station or county sheriff office, breath sample has like 72 hr shelf life and longer if the temperature is right, Hand Held THC Breathalyzer when it fails is the ticket and a ride down town, sample will be tested there and if you have a Hand Held THC Metered Level Breathalyzer it would need to be calibrated and court certified, best to have just the 1 unit to test and certified for the court, it'll also give the violator the glimmer of hope that the Test Kit will pass him or her
