A Review of the Landscape of State Tobacco 21 Laws: Key Components, Research Challenges, and Future Directions

BackgroundTo understand the impact of laws raising minimum legal sales age for tobacco products to age 21, researchers and policymakers need to recognize how recommended policy components vary across states. This paper identified and reviewed policy components across 43 jurisdictions that have enacted Tobacco 21 (T21) laws since 2015.MethodsUsing NexisUni’s database of state laws and legislation, we evaluated T21 laws in effect as of January 2024 and assessed for the incorporation of six components recommended in proposed model legislation: 1) age verification; 2) tobacco retailer licensing; 3) provisions to suspend or revoke a license; 4) unannounced inspections; 5) retailer civil or criminal penalties; and 6) provisions that allow for more stringent local laws.ResultsOnly two states included all six components we reviewed, including limiting penalties to civil fines. All jurisdictions included a provision to change the legal sales age of purchase and 38 imposed requirements on retailers to verify identification. Thirty-eight jurisdictions had licensing programs, but only 32 included license suspension or revocation provisions for underage sales. Nineteen jurisdictions preempt localities from imposing more stringent requirements. Twenty-four jurisdictions use a mix of civil and criminal or solely criminal penalties and 21 jurisdictions have penalties for underage purchasers.ConclusionsOur database of recommended T21 components with effective dates can be merged with other datasets to facilitate policy evaluation. We discuss ways to enhance research and data collection in this area, and recommend that states update T21 laws to adopt all recommended policy components.
