It's a new day for 52-year-old Lynn Allen.

"This will make a big difference in my life," Allen said.

After suffering from HIV and Hepatitis C, he says Prop One is two steps forward for his future.

"Having access to medical marijuana will allow one more medication that will make my life easier," Allen said.

But before Prop One proponents get excited about its passage, they might want to read the fine print. It's not effective until December 4, and after that the state has 120 days to implement various restrictions and regulations.

"Once we get applications we're going to have 15 days to respond, and if we respond in favor, meaning we approve, then we have five days to get that person an ID card," said James McCurtis of the Michigan Department of Community Health.

But that's only after the state receives a certified document from a patient's physician, but even then, the I.D. card won't last a lifetime.

"The date it was issued to that person, it will only last for one year, after that the identification card expires," McCurtis said.

But McCurtis says the law only covers the possession of marijuana, but purchasing it is a different story.

"Problems will occur, you have two laws here; to purchase marijuana is illegal but there's a state law that says, if you have this card and you posses it, then it is legal, so that's something that the police agencies will have to figure out," McCurtis said.
