The Michigan Senate has given the Legislature's final approval to bills that would ban so-called synthetic marijuana.
The substance, sold under trade names like Spice and K2, has been available in stores as a mix of dried herbs and spices sprayed with chemicals. It has been blamed for health problems and violent behavior, especially among young people.
Legislation approved Tuesday would crack down on synthetic cannabinoids and products sometimes referred to as bath salts. The bills also allow the Department of Community Health to declare health dangers when other synthetic drugs pop up.
The bills now go to Gov. Rick Snyder for his signature and immediate effect. Some counties and communities already have acted on their own to ban synthetic marijuana.
