Eight pot companies praised President Trump's recent promise not to crackdown on states with laws that contradict federal marijuana policy and said the move has already lit up sales nationwide.

Player's Network, Inc., a collection of eight publicly traded marijuana companies, said Trump's move "makes American cannabis great again" by boosting confidence in U.S. producers and luring investors from foreign markets.

"Now marijuana entrepreneurs and investors who had been intimidated by [Attorney General Jeff] Sessions’ overreach can be assured that American cannabis companies are poised to become world leaders in the emerging global industry," Player's Network said in a statement.

Last Friday, Sen. Cory Gardner, R-Colo., said he would block all presidential appointments to the Justice Department unless the Trump administration conceded to allow states to have their own pot policies that go against federal laws despite Sessions' recommendation against it.

Gardner spoke with Trump on April 13 and said the president had assured him "he will support a federalism-based legislative to fix this state's rights issues once and for all."

"Not only is prohibition becoming quickly antiquated, but legal marijuana will be among the fastest growing industries over the next few decades. As Pres. Trump and Sen. Gardner work to craft a legislative fix, we believe smart money will start pouring into American marijuana businesses," Player's Network Director Brett Pojuni and CFO Geoffrey Lawrence wrote in the statement.

The pot coalition expects the U.S. industry to grow from $9.2 billion last year to $43 billion by 2027.

"All due respect to Canada, but we believe American firms can and should produce the best, safest marijuana products in the world," the group added. "The best marijuana in the world can be grown in the United States, and that’s ultimately good for America."
