BOISE, Idaho (AP) — A proposed constitutional amendment that would prevent the legalization of marijuana and other psychoactive drugs has cleared the Idaho Senate and is headed to the House.

If it is passed there, Idaho voters will decide in 2022 whether to approve the amendment to the state constitution,

Backers say Idaho is surrounded by states with legal marijuana and they don’t want it.

Opponents say the measure would permanently ban medical marijuana for patients with terminal illnesses or chronic pain.
