Idaho lawmakers voted Jan. 29 to advance a joint resolution that would implement a constitutional ban on cannabis, according to an AP News report.

The Senate State Affairs Committee voted 6-2 to approve the proposed constitutional amendment, which would ban all psychoactive drugs that are not already legal in Idaho, the news outlet reported. The list of banned substances could then be adjusted if drugs are approved by the U.S. Food and Drug Administration, according to AP News.

The amendment’s supporters argue that neighboring states have legalized cannabis through voter-approved initiatives, which could also happen in Idaho, while those opposed said medical cannabis should be available for residents suffering from chronic or terminal illnesses, the news outlet reported.

The joint resolution needs to pass the Idaho Senate and House with two-thirds majority in each chamber, according to AP News, and would then go before voters in the 2022 election.
