New Mexico would have about 250,000 potential customers of cannabis should the state legalize adult recreational use of cannabis, an economist told the Senate Corporations and Transportation Committee yesterday. And those consumers would purchase roughly $412 million worth of the drug in the first year. The data was produced by Dr. Kelly O’Donnell, an economist who served as Director of State Tax Policy, Deputy Cabinet Secretary for Economic Development, and Superintendent of the New Mexico Regulation and Licensing Department during Gov. Bill Richardson’s administration. She now works as a consultant. Her report was commissioned by Ultra Health, a New Mexico provider of medical marijuana.
