Jason Nemes of Jefferson County said he plans to introduce a bill outlawing MCDs at the state level in the 2026 legislative session. “It mirrors federal law, which already says that these devices are unlawful, and it makes it unlawful in Kentucky as well,” Nemes said.

Savannah Maddox of Dry Ridge, voiced opposition to the proposed Kentucky ban.
