"I would imagine Ohio will probably mirror Michigan in a lot of ways," said Michigan-based attorney John Fraser.

The Wolverine State embraced full legalization in 2018, a move that was met with a mix of enthusiasm and anxiety.

"The reason the voters of Michigan decided to vote yes on our proposal was because prohibition was a failure," said Robin Schneider, executive director of the Michigan Cannabis Association.

"Initially, from a law enforcement standpoint, it was the unknown," said Ron Wiles, deputy director of the Michigan Association of Chiefs of Police.

WLWT investigator Todd Dykes asked Wiles how he views Michigan's legal weed marketplace.

"Is it good, bad, ugly? What do you make (of it)?" Dykes said.

"So I don't know if it's good, bad or ugly. It's a mix of all that, depending on how you look at the issue," Wiles said. "It wasn't as bad as what we originally anticipated."

For people like Wiles, the jury on adult cannabis use is still out.

"What impact will this have on our kids? We don't know that yet because we're only, what, five years into it in the state of Michigan," Wiles said.

He said a pressing concern is a rise in deadly traffic crashes.

"Fatalities are going through the roof right now," Wiles said. "Now, is that all because of marijuana? I am not saying that. But it happened. It's a fact. Those fatalities go up. Did marijuana play a role in that? Potentially. We see more drug driving cases now than we do alcohol-impaired driving cases now."

What frustrates police is the lack of easy-to-use, reliable tests that could prove if accidents are tied to marijuana use.

Advocates, meanwhile, are feeling a lot less frustrated. They argue legalization has been a boon, not a bust.

"All the misconceptions that, you know, that surrounds cannabis, you know, have for the most part been proven not to be true," said Sam Usman Jr., founder and CEO of Pure Options dispensary.

Usman has dispensaries on both sides of the state — in cities like Detroit and Muskegon. He's eager to learn the fate of Issue Two, knowing it could dent recreational and medical marijuana sales in Michigan.

"It's not new to Ohioans because they're coming up to Michigan by the droves," Usman said. "So, I mean, I'm pretty sure that Ohio's going to appreciate some of the tax revenue that Michigan is getting right now."

"We raised over $325 million in tax revenue for Michigan last year," Schneider said, referring to sales involving both recreational and medical marijuana in Michigan.

And the sales volume is staggering.

"This year in Michigan, we should do $3 billion-plus in sales — just this calendar year," Fraser said.

In his role as a lawyer, Fraser helps companies comply with Michigan's marijuana rules, which are designed to make sure the drug is properly tested and out of reach of kids.

He said if Ohioans approve recreational marijuana, the first batch of people waiting to make a purchase won't be strangers to the plant.

"Most of the people that are going to be, you know, customers in the Ohio-regulated marijuana market are already marijuana consumers, right? They've just been doing it illegally," Fraser said. "Now we're bringing that out of a state of prohibition, allowing people to have safe, regulated access to it."

But access to cannabis means different things to different people, especially someone like Wiles, who served for years as the police chief of Grand Blanc, Michigan.

"We hope it doesn't have any direct relation to an increase in crime or mental health issues, but we don't know that yet," Wiles said. "Those are all questions that we tried to find answers to. Some of those are a work in progress."

When it comes to traffic safety and marijuana, Wiles talked about training programs for police officers, including one offered by the Ohio State Highway Patrol. The program teaches police to be "drug recognition experts" and can involve more than 100 hours of training.

While safety issues are part of the debate surrounding cannabis, there's also the dollar sign aspect of legalizing marijuana. If Issue Two becomes law, researchers at Ohio State estimate tax revenue could total between $276 million and more than $400 million during the fifth year of legalization in the Buckeye State.
