Amazon has endorsed a Republican-backed bill in Congress on Tuesday that would legalize marijuana on a federal level, leaving states to decide whether to prohibit or regulate it.

Rep. Nancy Mace's (R-SC) States Reform Act would remove cannabis as a federal Schedule I substance and introduce a new 3% federal tax on the substance.

Revenue from the tax would be routed help fund law enforcement and veterans' health programs — and cannabis would remain illegal nationwide for anyone under 21 except for medical marijuana patients.

"Every state is different and every state should be able to dictate their cannabis laws," Mace told The Post in an interview. "This bill would get the federal government out of the way."

In a tweet on Tuesday, Amazon's public policy arm said it was "pleased to endorse" Mace's proposal.

"Like so many in this country, we believe it's time to reform the nation's cannabis policy and Amazon is committed to helping lead the effort," the company said.

Mace, a freshman Congresswoman who previously worked for Donald Trump's 2016 presidential campaign, told The Post that she was approached by Amazon representatives after she introduced the bill.

She said the company was motivated to endorse her bill because legal issues around marijuana can make hiring difficult.  [Read More @The NY Post]
