Mexico’s Supreme Court has decriminalized the use of marijuana for adults. The court’s ruling comes after the Mexican Congress failed to enact legislation legalizing recreational use of marijuana by the end of April — a deadline set by the Supreme Court. While many celebrated the ruling, some critics warned there are still legal loopholes that could criminalize people for cultivating or distributing marijuana. Efforts to legalize marijuana in Mexico are also aimed at curbing drug violence in the country. Since the U.S.-backed war on drugs was launched in 2006, over 300,000 people have been killed.
