The idea that the Federal government may crack down is certainly unsettling. Even without the detailed traceability public records data being available, the cat is already out of the bag.

For instance, by entering a highly regulated industry, these businesses have to submit a ton of paperwork - including federal income taxes, company formation documents, employment information, etc.. Furthermore, to operate successful, they have to advertise, and are already visible in print papers, billboards, trade shows, magazines, etc.

If anything, we hope that this data demonstrates that legal cannabis is an industry just like any other: prices go down as competition increases, variety and quality increase over time, jobs are created, there is significant tax revenue, etc.

One last thing: there is nothing identifying about the customers that is in this data, since everyone pays in cash.
