dingo, good post. I have actually been following this company for some time now but never invested due to a few things. Their 1.4 million negative balance sheet, complex company structure (they are owned by another company), also their authorized shares amount. They threw in narcotics testing in their presentation but the truth is they have been solely focused on detecting cancer from the beginning. They are not building this device to stand up to field use (durability) and I have no idea if their way of testing provides a specific time window like the Cannabix tech does. Also they only have a 5-year agreement with NASA for their technology, after that it expires (and its already been a few years). They might renew the agreement who knows, but that's a gamble. I do not know how this tech compared with the Cannabix method of testing. It may well be a good investment, but I do not think this is a direct competitor with Cannabix as of now. Also something that can only be used through an ipad or other device will ultimately be MUCH more expensive. That means for every unit you not only have to buy the device but also buy an expensive interface - this is not practical for police or commercial use like a construction environment for instance.
