The bill introduced in the U.S. Senate Thursday would allow  for written marijuana advertisements in states where cannabis is legal after the postal service sent out a memo  in December to all newspapers in legal states saying that they would not be able to distribute their papers if they carried paid adverts for marijuana (products) as US Post would be liable under federal law

They aim to amend the Controlled Substances Act so that any  restrictions on advertising would not apply to cannabis-related activities that are in compliance with laws at the state level.

Senator Wyden introduced the bill to protect “law-abiding Oregonians and small business owners” to and address concerns from local and federal officials from legal states.

“Our bill updates the federal approach to marijuana, ending the threat to news publications that choose to accept advertising from legal marijuana businesses in Oregon and other states where voters also have freely decided to legalize marijuana,” he said.

Merkley also spoke out against federal regulations that limit the capabilities of legitimate cannabis companies:

“Oregon voters have made it clear that they support marijuana legalization, but in area after area, federal regulation makes it difficult for legitimate marijuana businesses to operate. It’s time the federal government starts updating its rules and regulations in states where marijuana is now legal.”
