Effects of Tax Proposals and Cigarette Availability on Tobacco Purchasing

Официальное название

The Impact of Availability of Conventional Cigarettes and LNCs in the Context of Innovative Tax Proposals

Обзор

This study will investigate the effects of normal-nicotine versus low-nicotine cigarette availability in the context of four tax proposals (Tobacco Parity, Nicotine-Content, Harm-Reduction, and Modified Risk Tobacco Product-based taxes) on tobacco product purchasing patterns in a virtual marketplace.

Подробное описание

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.

• Поведенческое Harm Reduction Tax - Normal Nicotine Cigarettes Available
  In the Harm Reduction Tax Condition, tobacco products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. All combustible products with high abuse liability are placed in the high-tax tier. All non-combustible products or combustible products with low abuse liability are placed in the medium-tax tier. Nicotine Replacement Therapy products are placed in the no-tax tier. The participant's preferred normal-nicotine content cigarettes are available in

  In the Harm Reduction Tax Condition, tobacco products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. All combustible products with high abuse liability are placed in the high-tax tier. All non-combustible products or combustible products with low abuse liability are placed in the medium-tax tier.

• Поведенческое Modified Risk Tobacco Product Tax - Normal Nicotine Cigarettes Available
  In the Modified Risk Tobacco Products tax condition, tobacco products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. In this condition, all non-MRTP tobacco products are placed in the high-tax tier, MRTPs are placed in the medium-tax tier, and Nicotine Replacement Therapy products are placed in the no-tax tier.

• Поведенческое Modified Risk Tobacco Product Tax - Normal Nicotine Cigarettes Not Available
  In the Modified Risk Tobacco Products tax condition, tobacco products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. In this condition, all non-MRTP tobacco products are placed in the high-tax tier, MRTPs are placed in the medium-tax tier, and Nicotine Replacement Therapy products are placed in the no-tax tier. The participant's preferred normal-nicotine content cigarettes are NOT available in the marketplace. Participants complete two trials
• Поведенческое Nicotine Content Tax - Normal Nicotine Cigarettes Available
  In the Nicotine-Content Tax Condition, products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. In this condition, products with greater than 3 mg nicotine per single unit are placed in the high-tax tier, products with 0.6-3.0 mg/unit in the medium-tax tier, and those with 0.5 mg/unit or less in the no-tax tier. The participant's preferred normal-nicotine content cigarettes are available in the marketplace. Participants complete two trials wit

  In the Nicotine-Content Tax Condition, products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. In this condition, products with greater than 3 mg nicotine per single unit are placed in the high-tax tier, products with 0.6-3.0 mg/unit in the medium-tax tier, and those with 0.5 mg/unit or less in the no-tax tier.

• Поведенческое Tobacco Parity Tax - Normal Nicotine Cigarettes Available
  In the Tobacco Parity Tax condition, tobacco products in the Experimental Tobacco Marketplace are placed into three tax tiers: high-, medium-, and no-tax. In this condition, all tobacco products are placed in the high-tax tier while products that do not contain tobacco (e.g., herbal cigarettes and nicotine-free ENDS) are placed in the medium-tax tier. Nicotine Replacement Therapy products are placed in the no-tax tier. The participant's preferred normal-nicotine content cigarettes are available
