It's been more than a year since Florida voters overwhelmingly approved Amendment 2, legalizing medical marijuana. 

• Legalized medical marijuana in Florida still facing obstacles
• State health officials missed deadline to unveil rules 
• Lawsuits holding up process

However, it's still not available to tens of thousands of patients with chronic conditions. That's because state health officials have missed a key deadline to unveil some long-awaited medical marijuana rules. 

Governor Rick Scott's medical marijuana Czar, Christian Bax, faced a panel of frustrated state lawmakers Wednesday. He gave reasons why the administration hasn't rolled out all the rules to make legalization a reality. 

Bax pointed to lawsuits, brought by farmers who want to get their hands on medical marijuana licenses and even a printing company that wants to make patient ID cards, as the biggest obstacles. 

"For now, I can say that from the top to bottom, the department is 100 percent committed to making the process move efficiently for patients in Florida," he said. 

Bax also said his department gave approval to two new nurseries to begin growing full-potency medical marijuana. 

So far, 52,000 patients have enrolled in the state's medical marijuana registry.
