How long will the IRS be patient? $500M is a significant debt and it's an easy target. If you think about it, the IRS could request them to pay up sooner rather than later. I mean the FDA appointed a new cannabis-oriented individual. If the rest of the govt is also progressing slowly they might want to level the playing field and collect what they can/deserve before establishing or reviewing a new industry tax baseline. Heck, better yet the govt might just do it to prove a point...that regardless of how large you are, you are arent exempt from the govt.
