Just a few short months ago, Connecticut legislators from both parties were expecting to legalize recreational marijuana before the end of the legislative session on June 5.

But that date is soon approaching and both sides now agree there will be no vote on legalization this session.

What happened?

Three committees—Judiciary, General Law and Finance, and Revenue and Bonding—approved bills related to legalizing recreational marijuana, but the efforts all died.

Proponents and critics agree the measure didn't have enough support in the full state Legislature.

"I really thought it would pass, but people got scared from the potential backlash from their constituents," said Democratic State Rep. Phil Young, who supports legalization with the criteria that there is proper education and enforcement. "There was just not enough support in the [Democratic] caucus. The Republicans would vote as a block against it, while Democrats are mixed on the issue. The votes are just not there."

Democratic State Sen. Dennis Bradley, who also supported legalization with educational caveats, said many of his colleagues appeared worried about the strong anti-legalization advocacy within the state.

"I think that rhetoric from the right and the demonization of marijuana as the big bad boogeyman got some momentum," Bradley told the Connecticut Law Tribune Thursday. "There were also some within the religious community that were opposed."

One of the strongest anti-legalization voices in the Connecticut Legislature is Republican Rep. Vincent Candelora.

Candelora, who told the Connecticut Law Tribune in November he thought Connecticut would pass a bill allowing for recreational marijuana, said Thursday that things had changed.

"I think the people that were neutral moved to a 'no,'" he said. "I think they moved to a 'no' because of the science. They recognized the negative impacts of marijuana."

But calling Connecticut's medical marijuana laws "the gold standard for the country," Young said he favors legalization for recreational use, if the same efforts that went into medical marijuana legalization were put into legalizing the drug for the rest of the population.

"We went into such fine detail with our medical marijuana laws," Young said. "With medical marijuana all the systems with regard to prescribing and law enforcement were researched and in place. I want to make sure the same thing is done with recreational marijuana. There needs to be things like education and age requirements, meaning at least 21 years old."

Candelora said any financial upsides to OK'ing legalization in Connecticut pale in comparison to the downsides. There are many, he said.

"Just look at Colorado, which has had legal recreational marijuana for several years," Candelora said. "The statistics there show a big negative impact. Car fatalities have increased and homelessness has increased."

Government estimates indicate recreational marijuana could generate upward of $30 million in tax revenue for Connecticut in the first year, according to the Connecticut General Assembly's nonpartisan Office of Fiscal Analysis.

Both sides agree the probable scenario will be a state referendum, most likely in 2021.

If that is the case, Candelora expects the public would vote for it, with help from the pro-marijuana lobbying efforts.

"Taking it to referendum would be a matter of trying to educate the public," Candelora said. "Unfortunately, billions of dollars in industry money will be dumped into advertising to promote legalization. I think a referendum would pass because of the lobbying."
