LAS VEGAS, NV - JULY 06: Marijuana plants are grown at Essence Vegas' 54,000-square-foot marijuana cultivation facility on July 6, 2017 in Las Vegas, Nevada. On July 1, Nevada joined seven other states allowing recreational marijuana use and became the first of four states that voted to legalize recreational sales in November's election to allow dispensaries to sell cannabis for recreational use to anyone over 21. Since July 1, sales of cannabis products in the state have generated more than USD 1 million in tax revenue. (Photo by Ethan Miller/Getty Images)
