Making good on his promise to file another constitutional amendment to legalize medical marijuana, Orlando attorney John Morgan on Thursday filed a revised version of his original proposal with the Florida Secretary of State's office.

Morgan, who spearheaded the constitutional amendment that won 58 percent of the vote in November, said the new amendment "is essentially the same amendment with clarifications." (Here's full story with side-by-side analysis.)

If he collects enough signatures, and wins court approval, it will be on the 2016 presidential ballot.

The original Amendment 2 failed to become law despite collecting a majority of votes because it fell short of the 60 percent threshold needed for constitutional initiatives in Florida.

Morgan told the Herald/Times he would prefer that the issue be addressed by the Legislature, so that it is not embedded into the state Constitution, but because lawmakers have not shown a desire to act he will make one more try.

"After this, I'll never do this again,'' Morgan told the Herald/Times. "The lesson in playing big is you set yourself up to lose big and losing big gives you humility and perspective that I didn't have when I was trying to find my way in the woods on this the first time."

Among the lessons learned, he said: "A lot of it was about me and it should be less about me and more about the patients." He said he also wrongly assumed the first time that if he got young voters out to the polls to vote for the amendment, it would pass. "But they didn't come out to vote,'' he said.

Meanwhile, Amendment 2 lost the greatest share of voters among those 65 and older and they are "the people most likely to benefit,'' he said.
