U.S.A. IS GOING GREEN


Less than two decades ago, marijuana was illegal in all 50 U.S. states. With Utah and Missouri passing ballot initiatives in November 2018 to legalize medical marijuana, 33 U.S. states now have broad legislation in place that allows of the use of marijuana. Although the decriminalization of marijuana in the U.S. began in 1973, it wasn't until 1996 that the journey toward legalization began. Here are the most significant milestones for legalizing marijuana in the United States. (Data Sources: National Conference of State Legislatures, CNN)
