A Billings car-dealership owner has proposed a ballot measure that would completely ban the use and possession of marijuana in Montana, even for medical uses.

The proposal by Steve Zabawa would change state law to say any Schedule I drug in the federal Controlled Substances Act is illegal.

Zabawa says the proposal submitted to the Montana Secretary of State's Office on Thursday aims to eliminate the disparity between federal and state law in possessing and using marijuana, which is a Schedule I drug.

Montana and several other states allow the regulated use of marijuana for medical purposes, and about 8,300 medical marijuana users are registered in Montana. Two other states, Washington and Colorado, have approved recreational use of the drug, and federal authorities have not interfered.
