Most of the volume is fromthe US. 1.4 million dump from american investors. Some body possibly hit the sell button from frustration or the fact that there are a ton of newcomers ipo'ing outside the States despite the Nixon era rules and regulations endorsed by the Feds who are still entrenched with the idea that marijuana should be lumped in with Heroin and other killer drugs. The point is that a THC breathalyzer isn't as easy as to do as a blood alcohol breathalyzer and I have this rated as a red or black bet, but I do believe who-ever comes up with a working breathalyzer is going to make a ton of money because necessity is the mother of invention. It doesn't bely the fact that there are a lot of newcomers and old established companies that are starting to roar with greenrush investments that aren't as cut and dry as a thc breathalyzer. Red or black but don't mortgage the house. Dixie, Tinley, Plus, Grin, Nu Energy and a dozen or two more have the potential to move before we see a thc breathalyzer, but when we do see a thc unit, we will also see $30-$40 for one that works as described. Swabalyzers are already on the ropes because they aren't fair and will easily be beat in court. THC breathalzyer with a recent window for use is the best option if somebody can do it. I do like Cannabix as most likely to succeed. glta and dyodd
