Michigan State Police will begin removing so-called synthetic marijuana from store shelves if businesses haven't acted.
Laws recently signed by Gov. Rick Snyder target synthetic cannabinoids and products sometimes referred to as bath salts. Michigan State Police has the authority to remove them from stores starting Sunday if they're still being sold.
Synthetic marijuana is often sold under the names Spice or K2 and has been marketed as a mix of dried herbs and spices sprayed with chemicals. The substances have been blamed for health problems and violent behavior, especially among young people.
Anyone caught making, distributing or selling the substances can be charged with a felony that carries a maximum punishment of seven years in prison. Possession can bring two years.
