BOISE, Idaho (AP) — As legal weed becomes a reality across the U.S., Idaho is putting up a fight. A proposed constitutional amendment that would prevent the legalization of pot in the state moved forward on Friday. The Senate State Affairs Committee voted to approve a joint resolution that bans all psychoactive drugs not already legal in the state. Backers say the state Constitution needs to be changed because neighboring states have approved marijuana use, and it could happen in Idaho. Those opposed say medical marijuana is needed for residents suffering from chronic or terminal illnesses. The measure would have to pass the Senate and House with a two-thirds majority before going to voters in Nov. 2022.
