Indiana Governor Mike Braun has signed a new law prohibiting marijuana advertising within the state’s borders. The legislation, House Bill 1390, was passed by the Indiana General Assembly on April 29, the final day of the 2025 legislative session. While the bill primarily focuses on clarifying procedures for the Bureau of Motor Vehicles, it also includes a provision banning advertising for products containing marijuana or listed as a Schedule I controlled substance.
This move comes as recreational marijuana use is legal in neighboring states Michigan, Ohio, and Illinois, leading to many businesses from these states advertising in Indiana to encourage consumers to purchase and use the drug while crossing the border. Under the new law, any form of marijuana advertising within Indiana could result in fines of $5,000 for first-time offenders and $15,000 for repeat offenders.
The law will be enforced by the Indiana Attorney General’s Office, and any active agreements for marijuana advertising will not be canceled until 2035. The new law aims to curb the influence of neighboring states’ marijuana industries on Indiana’s residents and to promote a consistent approach to drug regulation within the state.
