Maryland has firmly positioned itself as a state with some of the most comprehensive and stringent vaping regulations in the United States. Driven by a strong commitment to public health, particularly the prevention of youth access to nicotine and the desire to maintain clean air standards, the Old Line State has implemented a multi-layered system of laws that have significantly transformed the vaping landscape, especially following major legislative changes in 2024 and 2025. This framework combines strict age restrictions, a broad ban on flavored e-cigarettes, comprehensive public use prohibitions, aggressive taxation policies, and detailed retailer responsibilities.
