Several state lawmakers will soon submit three different proposals to legalize recreational marijuana and let the state reap tax benefits from the industry. Analysts say legalized pot is a potential billion-dollar industry for the state. Two co-sponsorship memos circulating in both the House and Senate propose selling marijuana in state-owned liquor stores and restricting its possession and use to adults who are at least 21. Another measure would provide social justice to those with low-level marijuana convictions.
