Nevada plans to be the first state to create its own banking system for the legal marijuana industry, which has generated at least $150 million in tax revenue since 2017, according to Nevada Treasurer Zach Conine. Since the drug is still illegal under federal law, legal pot is mainly a cash business. Under a three-year pilot program, Nevada will allow marijuana businesses and consumers to deal in electronic tokens. They say it’s similar to casinos, where players buy and bet with chips. Conine says you exchange cash for casino chips and those chips transfer around the casino. When your done you convert them back into cash.
