Interventions and Outcome Measures

Arms

experimental: Exclusive cigarette smokers

Exclusive cigarette smokers will be recruited and will be exposed to all of the conditions described in the intervention section.

experimental: Dual cigarette/ nicotine vaping product users

Dual cigarette and nicotine vaping product users will be recruited and will be exposed to all of the conditions described in the intervention section

Interventions

Nicotine Content

In the full nicotine conditions, participants' preferred cigarettes and NVP products will be available in the LETM and preferred cigarettes will be available in the iETM. In the low nicotine conditions, a ban will permit only VLNCs in the LETM and preferred cigarettes will be available in the iETM.

Illegal cigarette price

At each level of nicotine content, we will manipulate the price of illegal cigarettes (1xMP, 1.5x MP, 2x MP). MP is market price.

E-cigarette price

At each level of nicotine content and illegal cigarette price, we will manipulate the price of e-cigarettes (1xMP, 1.5x MP, 2x MP). MP is the market price.

Primary outcome measure

  • Percent of budget allocated to each product category (eg, legal cigarettes, e-cigarettes, illegal cigarettes, etc) in the marketplace [ Time Frame: 1 day ]
