The letter about the special session notes Glenn, a Baltimore Democrat, had already achieved two of the goals she would have sought to accomplish in a special session. Hogan announced in late April he would launch a study of racial disparity in the medical marijuana industry, a step necessary if the state were to award new licenses that take into account an applicant's race. The letter also notes that last month Hogan replaced 10 of the 16 medical marijuana regulators, who were widely criticized by Glenn and other lawmakers.
