There are three state proposals St. Clair County residents will be deciding on today’s ballot one of which would allow individuals 21 and older to purchase, possess and use marijuana and marijuana-infused edibles, and grow up to 12 marijuana plants for personal consumption. The ruling would impose a 10-ounce limit for marijuana kept at residences and require amounts over 2.5 ounces be secured in locked containers. It would create a state licensing system for marijuana businesses and allow municipalities to ban or restrict them. It would also permit retail sales of marijuana and edibles subject to a 10% tax, which would be dedicated to implementation costs, clinical trials, schools, roads, and municipalities where marijuana businesses are located. It would also change several current violations from crimes to civil infractions. Polls are open until 8 p.m. this evening.
