Marihuana: advertising; use of billboards to advertise medical marihuana; prohibit. Amends secs. 102 & 206 of 2016 PA 281 (MCL 333.27102 & 333.27206) & adds sec. 506.

HB 5135 prohibits medical marijuana businesses from using billboards - including digital billboards - to advertise their products or services in Michigan. The bill amends the Medical Marihuana Facilities Licensing Act to add a specific ban on billboard advertising, directly affecting licensed dispensaries, growers, and processors that previously used this advertising method. This prohibition applies to all billboards as defined by state law (including digital displays under the Highway Advertising Act of 1972). The change does not restrict other advertising methods, such as online or print media, and aligns with existing rules limiting marijuana promotion near schools or parks.
