While there's broad agreement on the idea of legalization, there's no consensus on a long list of details that must be figured out first.
Taxes and regulations must be approved. Rules for licensing retailers must be written. A new government entity may have to be created. Local governments will have to be brought in. Even after a bill passes, it could take a year or more for any pot shops to open, based on what's happened in other states and New York's own experience with medical marijuana.
While reaching a compromise will prove difficult, lawmakers in New York say they have the advantages of seeing what's worked and what hasn't in other states that have eliminated the ban. That growing list includes Washington, Colorado, California and now neighboring Massachusetts.
"There does seem to be this air of inevitability," said Sen. James Skoufis, a Democrat from the Hudson Valley's Orange County. "But we need to make sure we do it right."
LEGALIZE WHAT, EXACTLY?
First off, lawmakers will have to set the broad parameters of the law. All legalization proposals so far would eliminate legal penalties for the adult use of marijuana in a private home. Almost all would permit retail shops where people could buy the product.
But what about Amsterdam-style pot cafes, where users could partake on site, while perhaps enjoying food, a cup of coffee or even an alcoholic beverage? Would people be allowed to consume marijuana outside? In their cars? At hotels? While children are present? Should local governments be able to prohibit pot shops in a certain town or county?
States have taken their own approach to each question. California allows pot cafes, while other states do not. Washington, the first state to legalize marijuana, requires users to smoke in their own homes or, if they rent, with their landlord's permission. Vermont's law legalizes possession and use of marijuana but makes no provisions for retail sales.
So far, the 10 states that have legalized weed have all put in place a minimum age of 21, mirroring the rules for alcohol. Some supporters, including the New York Public Interest Research Group, say the age should be set at 18 in New York, arguing that picking 21 would only push younger users to the black market.
The growing list of states is one reason why lawmakers say they want to legalize marijuana in New York this year. Officials in New Jersey and Connecticut are also weighing legalization, and Massachusetts and Vermont have already done it. Officials say they don't want to be left behind and see New Yorkers travel to other states to spend their money.
"I think we're going to pass it," Cuomo said this past week when asked about the prospects for passage this year.
HOW FAST AND HOW MANY?
Will the state create a new agency to oversee marijuana, put it under the control of an existing office, such as the Department of Health, which oversees medical marijuana, or leave much of the decision to local governments?
The answer could determine how many retail shops are ultimately allowed, and when they might open.
New York has a history of taking a slow, cautious approach when it comes to pot. Lawmakers approved medical marijuana in 2014, but in a limited fashion. Only a handful of dispensaries were authorized, and only non-smokable forms of cannabis were allowed. Even then, the first dispensaries didn't open for nearly 18 months.
In California, many of the decisions about licensing and approving local pot retailers are given to local authorities, with the thinking that they know what works best for their community, residents and businesses. But opponents say it can lead to a confusing mishmash of rules and a lack of oversight.
Massachusetts took a far different approach, giving a state task force control over approving retail shops. That's led to a slower, more conservative roll out. Voters approved legal pot in the Bay State in 2016, but the first retail shops didn't open until late last year. Six are now open, compared to hundreds in California.
"New York has the benefit of not being the first to do this," said Sen. Todd Kaminsky, a Long Island Democrat. "There's a lot to learn from the rest of the country."
Democrats now control New York's Assembly, Senate and the governor's office, giving marijuana supporters a clear path to legal marijuana this year. But opponents remain, and they'll do what they can to fight or limit legalization.
The group questions how the state will discourage pregnant or nursing women from consuming pot, and whether enough will be done to keep the drug out of the hands of minors.
Local prosecutors have pointed out that law enforcement will have to consider the best ways of testing marijuana impairment in drivers, a difficult goal since the active ingredients in marijuana can stay in the bloodstream for weeks — long after the effects have worn off. That's a challenge supporters acknowledge as well.
Police and prosecutors around the country are struggling with the same issue. Field sobriety tests have long been used to catch drunken or drugged drivers, and many departments are stepping up their training now that they expect to encounter more drivers who have consumed marijuana. Washington state has established a legal limit for THC in a drivers' system, similar to the well-known 0.08 blood alcohol level used to catch drunken drivers. Other states are considering following suit.
"To us, the hardest thing to figure out is what do you do about driving under the influence," said Blair Horner, director of the New York Public Interest Research Group.
Sen. Fred Akshar, a Republican from Broome County and a former undersheriff, said he and many of his colleagues remain concerned about the harmful effects of legalization.
"It's going to have a profound effect on public safety," Akshar said.
Among the toughest questions will be how much to charge in taxes and what to do with the revenue. And there's no shortage of ideas.
Some have suggested revenue could support repairs to New York City's aging subway system. Others want it spent on efforts to fight addiction and mental health. Many say it should just go into the state's general fund, like revenue from other taxes and fees.
Then there's the question of the appropriate tax rate, which creates a problem Goldilocks would understand: set the rate too high and consumers might buy from the black market or drive to nearby states where pot is cheaper. Set it too low and the program won't raise the money officials say the state needs.
"If you charge too much, you will drive the business back to the illegal sales because it is just less expensive," Cuomo told reporters Thursday.
REVISITING THE WAR ON DRUGS?
Marijuana legalization must be accompanied by the expungement of past criminal convictions for marijuana possession, according to Assembly Speaker Carl Heastie, a Bronx Democrat whose powerful position gives him significant influence over the debate.
Heastie and fellow pot supporter, Assembly Majority Leader Crystal Peoples-Stokes, a Buffalo Democrat, argue that thousands of black and Latino New Yorkers were unfairly targeted by police and prosecutors during decades of the war on drugs.
Proposals aimed at setting things right include giving minorities or residents of neighborhoods hard hit by the war on drugs precedence when it comes to licenses to grow or sell marijuana. Another would funnel some of the pot revenue toward efforts to help low-income neighborhoods.
