“But we do have problems with not being able to take tax deductions like a normal industry, or being able to have interstate commerce, which really creates a barrier to entry for a lot of folks.”But for now, at least, the industry appears to be growing in Arizona.Marijuana sales brought in $221.3 million in taxes in 2021, according to the Arizona Department of Revenue, and sales in 2022 were on pace to eclipse that number, with $196.4 million in taxes in the first nine months of the year.Alexis Villacis Aveiga, an assistant professor at the Morrison School of Agribusiness at Arizona State University, said that in order for cannabis to rival the rest of the 5 C’s, the state would need to see a much larger expansion of agricultural production.“For example, we have 35,000 square feet of indoors cannabis and hemp,” Aveiga said.Aveiga said current state regulations make hemp less attractive as a crop, since farmers can only sell their harvest if it is below the 0.3% limit for THC."
