A federally funded study published in the journal Health Economics confirms a direct correlation between high state-level cannabis taxation and consumer migration to the illicit market. Researchers from Ohio State University analyzed purchasing data from 1,525 adults aged 21 and older to determine how price sensitivity influences procurement channels. The findings indicate that when legal retail prices—inflated by heavy tax burdens—exceed a specific threshold, consumers increasingly bypass regulated dispensaries in favor of unregulated sources.
This trend poses a significant threat to the viability of the legal supply chain. As states compete to maximize tax revenue, they often overlook the elasticity of demand for cannabis products. The study suggests that excessive taxation acts as a primary catalyst for the persistence of the black market, undermining public health goals and regulatory oversight.
For business operators, this research quantifies the competitive disadvantage created by state fiscal policy. When the price gap between legal and illicit products widens, customer retention becomes increasingly difficult, regardless of product quality or brand loyalty. The data serves as an empirical warning to policymakers that aggressive tax structures may ultimately reduce total tax collection by shrinking the legal market share.
Industry stakeholders should use these findings to advocate for more sustainable tax models that prioritize market capture over short-term revenue gains. By maintaining competitive pricing, businesses can better transition consumers away from the illicit sector and into the safety of the regulated ecosystem.
