LANSING (WKZO) -- New measures outlawing the sale and possession of so-called "synthetic marijuana" took effect Sunday.  Individual communities began banning the substances, sold in convenience stores and gas stations under names like "K-2" and "spice."  It's now a seven-year felony to manufacture or distribute the substances, and a two-year felony for possession.  The new laws also authorizes health officials to designate any chemical variation of the drug as illegal, should manufacturers try to get around the law by reformulating the substance.
