Sacramento, CA – Senator Mike McGuire, who has been voicing concern over the last several months about the tight timelines associated with Proposition 64, will chair a Senate Governance and Finance Committee hearing next week focused on cannabis business taxes, implementing California’s Cannabis tax collection system and the “track and trace” system which verifies cannabis taxes and product safety – all critical elements of the structure for cannabis that is being developed, and that is slated to go live on January 1, 2018.
