Yep. An authorization is all thats required. You're not really doing anything by trying to call and verify. Its a felony to alter medical document for health purposes.
And ltes be realistic here too. No dispensary can ever be in compliance federally because its illegal federally and plus no dispensary can meet the legal requirements for filing income taxes. Are they going to keep receipts from there suppliers?lol I think not.
So just sell your product, there are people that need a safe way to get there meds and be prepared for the inevitable kick in the door. Be smart and hide the income and keep only a minimal amount of product and cash on site.
