More than sixty new medical marijuana businesses have incorporated in Florida in the last two months. Entrepreneurs are anticipating the passage of the medical marijuana amendment this November. It has been reported that supporters of amendment have pledged 20 million for TV ads in support of the ballot initiative and that 78% of Florida voters polled say they support the legalization of medical marijuana. So when should you expect the first medical marijuana dispensary to open? In other states it took at least a year from the passage medical marijuana to the first dispensary opening.
