More than 150 people are now believed to have been sickened by synthetic marijuana in Colorado, which legalized recreational use of real pot last November. Three people may have died.
State and federal investigators are scrambling to identify the exact source of the illnesses. The state health department has named about a dozen illicit products, often sold as "incense," that it believes are responsible for at least some of the illnesses. The stuff goes by names like "Spice," "Crazy Clown" and "Dead Man Walking."
