For all the progress that legal marijuana has made in the United States, the country remains a murky place for companies seeking to enter a nascent market with complicated and inconsistent laws, said the co-founder and chief executive of North America's largest cannabis company.

Bruce Linton, the CEO of Canopy Growth Corporation, said his company was able to lead the way and become the first publicly listed pot company because it scrupulously follows the rules.

"United States is getting more complicated," Linton said in an interview Thursday with Cheddar. "I'm not hearing as clear as a voice as I did on what to do three years ago. It's louder, but it's definitely not clearer."

Canopy was the first cannabis firm to be listed on the New York Stock Exchange when it began trading last week. Its stock is up more than 20 percent since its debut, and the company has a market cap of more than $6 billion. That makes it the largest pot stock out there. The Canadian marijuana company operates 10 production facilities in nine countries where pot is legal.

Linton said he wants Canopy to be a leader in the industry. "This is about public policy and how we push the agenda, and then follow it," he said, adding legalization should come from following existing rules.

"If you want to be on the New York Stock Exchange, you need to be following all the rules," said Linton. "What we try to do is lead, and that almost always results in having us do most things first."

Canopy Growth Corporation is used to doing this first. Before listing on the NYSE, it was the first cannabis company to go public when it listed on the TSX Venture Exchange, a junior exchange in Canada, in 2014. It moved to the Toronto Stock Exchange two years later.
