LANSING (WKZO) --   Governor Rick Snyder has signed a package of bills that will outlaw K2, Spice and other synthetic drugs in Michigan.

One of the bills updates the list of chemicals used to make synthetic drugs and would make them illegal to possess and sell. Another would give the state the power to temporarily ban a substance if the director of the Michigan Department of Community Health deemed it an imminent danger to people's health.

The drugs have been selling from gas station and convenience store shelves, with no law in place to stop them, and the drug's designers reconfiguring them to stay one step ahead of the law. 

The ban will go into effect July 1st.
