Missouri Amendment 3, Marijuana Legalization Initiative (2022), may require employers to revisit and redraft their policies. Amendment 3 includes a provision that prohibits employers from discriminating against employees who: (1) possess medical marijuana cards; (2) lawfully use marijuana during nonworking hours when not on the employer’s premises; or (3) test positive for marijuana (except for employees who use, possess, or are under the influence of marijuana while working).
