LANSING, Mich (WLMI)  Governor Snyder will sign legislation today toughening up the state's laws against synthetic drugs like K-2 and Spice.  The four bills sailed through the Legislature in the past few weeks after counties started enacting their own bans on the drugs.  State law had banned the substances, but the manufacturers were able to change a few parts of their chemical makeup to keep them legal. The new bills will close those loopholes.
