Beth Kassab: Medical marijuana in Florida is a done deal.

Widespread medical marijuana in Florida is already a done deal.

The question now is how badly we screw it up.

Yes, technically, it’s too early to predict these things.

Amendment 2, which would open the door for much-expanded use of pot to treat a variety of diseases, isn’t on the ballot until November.

And, admittedly, I called a win for Amendment 2 — even though I opposed it — the first time it was on the ballot in 2014.

The medical pot initiative lost by just 2 percentage points that year.

This time, though, there are some marked differences.

For one, the state’s new law that allows very limited access to medical marijuana will begin in earnest when the first pot dispensary opens today in Tallahassee not far from a nail salon, a hearing aid outlet and a frame shop.

Trulieve, the only company authorized by the state so far to begin selling, will offer only low THC pot at first (the kind that doesn’t cause a high), but will move into the full-strength stuff soon.

Chances are, by November, there could be another shop or two in the mix. A second state-sanctioned dispensary Alpha Foliage, which uses the name Surterra Therapeutics for its marijuana operation, is going through the final approval process to begin selling.

A lot of voters likely won’t consider Amendment 2 to be a leap into new territory (as it was in 2014), but more of a logical next step.

A Florida law that allows the low-THC variety was mired in lawsuits and regulatory challenges for two years, but the first patient finally received home delivery of the drug over the weekend and more will likely take advantage of the storefront opening in Tallahassee.

Soon, people who are dying will be able to buy full-strength marijuana. The Legislature made that change earlier this year.

Florida is also showing a growing appetite for decriminalizing pot.

Orlando became the latest city in May to give police officers the option of issuing a ticket rather than arresting people with small amounts of the drug. At least nine other cities and counties recently passed similar ordinances from Key West to Volusia County.

Another key change: Back in 2014, the Florida Sheriff ’s Association was heavily involved in an education campaign against the amendment called “Don’t Let Florida Go to Pot.”

This year that appears to be less of a priority and more individual sheriffs are expressing their personal views. Flagler County Sheriff Jim Manfre said he isn’t against medical use of the drug.

“I think you’re going to hear, perhaps, more sheriffs and maybe police chiefs or active law enforcement who have learned of the benefits of medical marijuana who will be supportive this time,” Manfre told Politico.

The latest poll released by United for Care, the pro-medical marijuana group largely funded by Orlando personal injury attorney John Morgan, puts approval among likely Florida voters at 77 percent. At least 60 percent must vote for the amendment for it to pass.

All of this adds up to odds in favor of passage this year. Fine. I’ll concede my reservations about normalizing drug use, especially around kids and specifically at a time when we have a heroin and fentanyl crisis in this state, put me in the minority.

That’s not to say there isn’t organized opposition against Amendment 2. There is.

The family trust tied to the founders of Publix Super Markets recently contributed $800,000 to the campaign against the amendment.

But a more productive discussion right now might be how to keep marijuana use limited to doctor-approved patients rather than defeat the measure entirely.

Orlando and other towns are smartly taking steps to withhold approval of pot dispensaries until they come up with rules about how close the shops can be to schools or churches and to each other. That makes sense. Also worth looking at are the public health impacts.

Colorado learned the hard way about edibles. That state ordered changes to the way candy and baked goods infused with marijuana are labeled and packaged — including more child-resistant containers.

Hospitalizations related to marijuana surged after the drug became widely legal in Colorado in 2014 from 803 per 100,000 to 2,413 per 100,000, a report from the Colorado Department of Public Safety noted earlier this year.

Florida needs to make sure its marijuana industry, which represents the potential for big money in this state, remains tightly regulated.

If Florida is going to do this, we need to do it right.
