With a budget crisis confronting the New Mexico Legislature, some legislators plan to float a controversial idea gaining momentum across the nation: Legalize the adult use of recreational marijuana, or cannabis. Adult recreational use is now allowed in eight states plus the District of Columbia, and more than 25 already authorize it for medicinal purposes. And in 2016, after three years of being bogged down in Senate committees, an effort to legalize recreational use in New Mexico made it to the Senate floor for a vote. Last year’s Senate Joint Resolution 5, sponsored by Democratic Sen. Gerald Ortiz y Pino of Albuquerque, asked voters to amend the state’s constitution to allow possession and personal use of cannabis by people 21 years or older. It would also have regulated production and sale of cannabis, and allowed collection of a tax on the sale of the drug.
