Two petitions that would affect taxes on tobacco products in Missouri are going through the approval process for circulation.

One would give cities and counties the ability to set and control tobacco taxes. The state has preempted local tobacco taxes since 1993.

Petitions supporters say local communities should have the right to determine how tobacco tax dollars are used. But Misty Snodgrass with the American Cancer Society says the proposal is problematic.
