Brief summary
This study will investigate the effects of a very-low-nicotine cigarette (VLNC) standard, e-cigarette price, and illegal cigarette price on illegal product purchasing and alternative product use in a virtual marketplace.
Detailed description
This experiment will examine the effects of a VLNC standard, electronic cigarette price, and illegal cigarette price on illegal cigarette purchasing. Exclusive cigarette smokers and dual cigarette/nicotine vaping product (NVP) users, stratified by age, will complete multiple scenarios in the legal Experimental Tobacco Marketplace. The investigators will examine the effects of a VLNC standard, predicted to promote illegal purchasing. In the NNC conditions, participants' preferred normal nicotine content (NNC) cigarettes, NVPs, and a variety of other products will be available in the ETM, and preferred NNC cigarettes will also be available in the illegal marketplace. In the VLNC standard conditions, a ban will permit only VLNCs legally in the ETM, but preferred NNC cigarettes will continue to be available illegal marketplace. In this experiment, which will be completed in the lab, we will test three levels of NVP prices and three levels of illegal cigarette prices in scenarios under a VLNC standard or NNC condition. This study will involve a total of three sessions, including an assessment session, an ETM session, and a follow-up phone call.
Interventions
BEHAVIORALNicotine 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.
BEHAVIORALIllegal 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.
BEHAVIORALE-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.

Intervention model description
Participants will complete one ETM session with a total of 18 purchasing trials, 9 trials in each of the two conditions - NNC and VLNC. The participant's preferred cigarette will be available in both the LETM and iETM in the NNC condition. In the VLNC condition, the preferred cigarette will be available only in the iETM and VLN cigarettes will be available in the LETM. E-cigarettes, nicotine replacement therapy, snus, and nicotine pouches will be available throughout all trials in the LETM. Within each condition, we will manipulate the price of illegal cigarettes (1xMP, 1.5x MP, 2x MP). At each level of illegal cigarette price, we will also manipulate the price of NVP (1/2x MP, 1x MP, 2x MP). This design will permit the investigation and comparison of the effects of a VLNC standard as well as changes in illegal and NVP price. The investigators will counterbalance the order of the conditions within the ETM session.
