If the federal government legalizes cannabis, lawmakers should beware of monopolization by national corporations, says Shaleen Title, chief executive of the cannabis policy think tank Parabola Center. Title authored a paper on preventing monopolies in the marijuana market, outlining how domination by big business is a threat to the existing cannabis industry. She writes that “the recent wave of market consolidation and high barriers to entry for smaller actors foreshadow a future national market controlled by only a handful of companies.” Title cautions that tobacco and alcohol companies are quietly laying the groundwork with the hope of controlling the legal cannabis market.
