COLUMBUS, Ohio (Michigan News Source) — Michigan marijuana dispensaries may soon no longer serve Ohio customers if a state bill is approved by the Ohio legislature.

The Ohio state house representatives approved a bill which adds and refines restrictions on marijuana in the state, including making it illegal to use or possess marijuana that was acquired outside of Ohio.

An analysis from the Ohio legislature says the bill changes the current marijuana laws to only legalize medical, adult-use, and homegrown marijuana cultivated, processed and dispensed under Ohio’s new law, referred to as the Marijuana Control Law. Marijuana from all other locations will be treated as contraband.

This bill could take a bite out of Michigan’s marijuana economy. Ohioans voted to legalize marijuana in the state in 2023, but because prices are lower in Michigan than Ohio, many still purchase their weed across the border.

The bill, Senate Bill 56, also condenses many other Ohio marijuana regulations into one bill.

The Ohio Senate has yet to approve the bill. The Senate’s next session is scheduled for Dec. 10.
