Effects of Tax Proposals and Cigarette Availability on Tobacco Purchasing

In a within/between subjects design, the investigators will use an Experimental Tobacco Marketplace (ETM) to systematically impose four innovative tobacco/nicotine tax proposals (Tobacco Parity, Nicotine-Content, Harm-Reduction, and Modified Risk Tobacco Product-related taxes) covering a broad range of tax magnitudes. Participants will complete two control trials and one tax proposal condition, with and without the conventional cigarettes available in the marketplace. Each condition (with and without conventional cigarettes) will include five price scenarios, with tax rates increasing across scenarios by a multiplicative factor. Tobacco products are placed into three tax tiers: high-, medium-, and no-tax, according to the goals of each proposal.
