Shares of Canadian pot producer Aurora Cannabis have been on a rollercoaster this year, surging after Reddit day traders took interest, only to tumble thanks to a less-than-stellar earnings report. But the company sees the light at the end of the tunnel when it comes to U.S. legalization, and Aurora Cannabis CEO Miguel Martin told Cheddar that he thinks the Canadian company is well positioned for when the U.S. makes the jump. Martin also says that he expects the U.S. to take a science-based approach to legalization, which would give Aurora 'significant advantages' in the U.S. market.
