I totally agree with you because the pot train left the station decades ago and there is always that faction that think they are ok to drive when they are stoned out of their gourd. The holy grail might come from the BTH device to detect all things that you shouldn't be doing and driving. I know they are the same device with a different nozzle and I think the pot breathalyzer one trick pony is the fast track that can make some big bucks for like minded investors and the new improved model that detects coke and fentanyl and oxy or bath salts or whatever stoned drivers are taking will arrive shortly after the first pot breathalyzer. I can imagine the cop saying that you are ok to drive but go see your doc because you have cancer markers. We live in interesting times and this could have a huge pop in sp for the first to succeed. glta and dyodd
