RESUMO
PURPOSE: Dietary supplements sold for weight loss pose a risk to public health due to deceptive claims and unscrupulous manufacturing practices in the context of weak federal regulation. Efforts to strengthen U.S. federal oversight have not been successful, thus action at the state and local levels should be explored. This study investigates proposed action to impose excise taxes on weight-loss supplements. METHODS: We reviewed U.S. federal law on taxation at federal, state, and local levels and precedent for taxation of harmful consumer products to promote public health. We assessed the rationale, legal viability, and potential effectiveness of proposed excise taxes on weight loss supplements. RESULTS: Taxation of tobacco and sweetened beverages is effective in reducing consumer use. Imposition of excise taxes on weight-loss supplements is within the authority of federal, state, and local governments, though is least politically feasible at the federal level. State or local taxation of these products has clear rationale, legal viability, and likelihood of effectiveness in reducing the public health burden posed by these products. CONCLUSIONS: Excise taxation is an effective policy intervention to reduce consumer use, particularly among youth, and is a promising public health strategy to decrease consumer exposure to noxious weight-loss supplements.
