This is something still way, way off in the future and there is no news that there has been any success at all in doing this. This is the technology that they, Lifeloc, have a license to use. https://ip.sandia.gov/techpdfs/SpinDx%20market%20sheet_final_1_2_3_4.pdf I haven't seen that much else, other than the license agreement has happened.
I own this as a long hold, because they have been a successful company in the past and could, if they can figure it out, be a player in the MJ detection game.
