Demonstrators pretend to smoke fake marijuana cigarettes during a protest for the decriminalization of marijuana in La Alameda park, in this May 4, 2002 file photo in Mexico City. Police and business owners from Mexico's beaches to border cities worried Sunday, April 30, 2006 that a measure passed to decriminalize possession of cocaine, heroin and other drugs could attract droves of tourists solely looking to get high.
