TRENTON - Today marks the deadline for groups to apply to grow and sell medical marijuana legally in New Jersey, but there may not be a rush of applicants.

Prospective licensees and advocates say rules and regulations being set up are complicating the process. They say the state proposed rules are so restrictive that their operations might not be viable.

Even though the rules aren't finalized, the state is moving ahead with its application deadline. The Legislature is also considering forcing a rewrite of the proposed regulations.

With all the uncertainty, some groups that want to provide medical marijuana are reluctant to pay the $20,000 application fee.
