Very strict definition of the 70/30 rule.
First issue, already addressed, is the broad definition of inventory.
Second issue, is that you are only allowed to sell up to 30% of your yearly crop. Yearly, not daily.
This will hinder wholesale sales for no apparent reason. What is the big concern if you can track where the medical marijuana came from and where it went?
Note: Sales to IPMs does not count towards the 70/30 numbers.
