New Jersey is moving ahead with its Monday deadline for prospective dealers to apply to legally grow and sell medical marijuana, but there may not be a rush of applicants.

Eligible patients and physicians are balking at the $20,000 application fee because of regulations about how the pot is distributed. They say the proposed rules are so restrictive that their operations might not be viable.

Groups are also hesitant because it’s unclear whether the current rules will remain in place in the future. The Legislature wants to force health officials to rewrite the proposed regulations and one group has gone to court to try and get the deadline pushed back.

With all the uncertainty, physicians and health centers that want to provide pot might miss the deadline entirely.
