Owners of Berkeley’s biggest medical marijuana dispensary, Berkeley Patients Group, are hoping for a settlement behind closed doors on a $6.3 million tax bill. The three-year-old tax case drew fresh headlines recently when the California Board of Equalization issued a press release re-iterating the board’s stance on the dispensary’s tax problems. However, Berkeley Patients Group’s operations have not been affected by the tax dispute and the dispensary is not in danger of closing, said spokesman Brad Senesac. The dispensary, in fact, just opened up a new space for patient services.
