By signing the bills, Gov. Michelle Lujan Grisham would extend legal recreational pot sales in the American Southwest by April 2022, when the New Mexico legislation kicks in, and join 16 states that have legalized marijuana, mostly through direct ballot initiatives. California and Colorado were among the first in the U.S. to legalize marijuana, with Arizona becoming one of the latest in the region to follow suit earlier this year. New York Gov. Andrew Cuomo signed a legalization bill Wednesday, and a proposal in Virginia is awaiting the governor’s signature.
