MIAMI — The medical marijuana industrial-complex is in full swing in Florida.

With the question of legalizing medical marijuana apparently heading to voters on the Nov. 4 ballot, entrepreneurs are popping up in an effort to get in on the ground floor of the movement.

Eighteen medical marijuana companies have registered with the state this year. Medical Marijuana of Brevard LLC, Medical Marijuana Business Lawyers LLC and Medical Marijuana Centers of Florida Inc., are among the first positioning to take advantage of a boom, should Florida voters approve the referendum by a 60 percent margin.
